Happiness Parents
Recently, we had our very last show choir concert of the 2009-1010 show choirs. It went really well considering we have only had one practice in the last month or two. While it was sad considering how many seniors are graduation and will not be apart of the choir program next year, it was also a really good concert. The parents put on a display of their own (as they do every year) mocking Happiness Inc.'s show this year. The above video is the from the concert, and is of the parents performance.
"The Hot Zone"

Most of the time, I really dread reading non-fiction books. I think it’s the stereotypical view that non-fiction are boring, that causes me to avoid realistic literature. But this book “The Hot Zone” was a fascinating story about several deadly viruses.
The “Hot Zone” discusses several different types of viruses, where major break outs have occurred, and the personal stories of several individuals who have encountered the viruses. One of the viruses that has been discussed is the Marburg Virus, and the author, Richard Preston, gives a vivid narration of a man named Charles Monet, who was infected and killed by this virus. Another Virus discussed in this book is the Ebola virus. Richard Preston discusses a little about the history of the virus, and also the story of a woman working with Ebola infected monkeys that almost contracted the disease herself.
The Marburg virus, and the two types of known Ebola viruses are in the same family and are all known as filoviruses. The two Ebola viruses are called Ebola Zaire, and Ebola Sudan. Of these three related viruses, Ebola Zaire is the worst, and Marburg is the best to contract. By no means however is Marburg a good virus to contract. When Charles Monet contracted the virus, his symptoms were painful headaches, red eyes, vomiting blood mixed with a black substance, and massive bleeding which finally resulted in his death.
One connection between the Marburg, Ebola Zaire, and Ebola Sudan virus is that they have largely affected both the physical, and mental well-being of many people who live in Africa. What then is the cause of each of these viruses, where can it most commonly be found, and what is it that should be avoided so as to not contract any of these viruses? Scientists still do not know from what, or where it was that Charles contracted the horrible Marburg virus that ended his life.
This information has a huge impact not only on our nation, or on Africa, but on the whole world. This is because these viruses don’t care what race or what ethnic group a person is from, all that matters to these viruses is finding a host. The information in this book is, in a sense, a warning of what a bad impact these viruses could have on everyone. In fact, there was one break out of the Ebola virus in Bumba that never spread much further than its origins. The reason for this is unknown, but breakouts like these have the potential to spread across the globe, infecting anyone, and everyone in its path.
We should care very much about this information because if a breakout of one of these viruses were to occur again, there could be countless casualties. We should care about finding a cure or prevention to these viruses, and gaining the knowledge of where they can be found.
I think that the information presented in “The Hot Zone” has both pros and cons. The pros are that we have been warned against a terrible virus, and have some time to do more research about it in preparation for a potential breakout. The cons of this information are the sheer terror it presents, and hopelessness of the truth that lies behind it. It makes a person realize just how fragile the people in our world are, how at any moment, something smaller than the period at the end of this sentence could easily destroy us, and at the moment, there is nothing we can do to stop it.
I think that even though this information isn’t pleasant, it is necessary to help the overall good of our world.
I like this book so far, I can relate all of the information about viruses back to my knowledge in biology. I like reading scientific literature like this because it is interesting, and it makes me feel smart because I am able to draw parallels between what I read and what I know.

College Tennis

Yesterday, after playing the defending state champion, I received an email from the coach of Coe College (a local area college) about considering attending Coe College after high school. The coach told me that he had come to my match that day and saw how I played, and he was impressed (even though I lost by such a convincing margin). I have considered attending Coe College before, but about the only thing that makes me not want to enroll there for college is the fact that it is so close to home.
Coe College is about eight minutes away from where I live right now, and as much as I want to consider going there, I’m just not sure if I would be happy going to school somewhere so close to home. When I picture myself at college, I picture myself starting out in a city that I am unfamiliar with, not in a place that I have spent my whole life.
I realize that there are a lot of perks of attending a local college, but right now, I really want to go to another, more distant city from where I am now.
All this considered, I have not ruled out the possibility of attending Coe College someday. While I have done very little research on any college, Coe seems to really be a great college, and the only thing deterring me from considering enrollment there is it’s location.

Marshalltown

Yesterday was the first tennis meet we played in that will help determine which teams qualify to play in the state tournament. We played Marshalltown and won the meet five one (Marshalltown is where the defending state champion attends school), and so we will be advancing to play one more school next Saturday, and if we win that meet, another school later that same day.
At the Marshalltown meet yesterday, I was most fortunate in that I was the one that got to play the defending state singles champion. It was an interesting experience.
While the score of our match wasn’t even relatively close (I lost zero and one), several games went to deuce, and I wouldn’t say that she completely blew me out of the water. I was able to return most of her serves (no small feat!) and we had several rallies that lasted for a respectable amount of time. Playing her was a neat experience for me because it helped me set goals for myself that I hope to achieve in the near future.

Ocean Reflux
I read an article about Ocean Reflux from "Discover" magazine, I wrote a response to it. Part of the article can be read online at http://bm.tribe.net/thread/1eeda22f-fecf-41bb-9d1d-ed1f45f72e94
This article was an informative piece that talked about the effects that green house gases, mainly CO2 were having on the ocean. Excess C02 is made as a waste product of several different things. Once CO2 is produced, the ocean absorbs the gas, and it lowers the Ph level of the ocean. This problem began with the start of the Industrial Revolution, and since the beginning of that time frame, the Ph of the ocean has dropped about 30%. Scientists were curious about the effect a more acidic environment would have on the marine life. Many experiments have been conducted, and most, if not all, have suggested that a more acidic environment is harmful to the underwater sea life. A more acidic environment causes many animals with shells to dissolve. Of course, with this known fact, it is now obvious that the ocean’s eco system will be greatly affected if the ocean’s water becomes too acidic. This would be a very bad thing because of the food chain. Certain animals that really on shelled-creatures as a source of food would die, and larger animals that rely on those animals would die, and so on and so forth. Another effect the rising acidity of the ocean will have, is on coral reefs. The Coral reefs do not thrive in very acidic environments, and if the Ph level is low, then reefs will start dying, and that wouldn’t be good because there are many animals that depend on the reefs for a habitat.
This information has an impact on the world, because if acid levels become too high in the oceans, than the “circle of life” will be thrown off balance, and some organisms would probably drastically decrease in population, or even become extinct. This article presents both good, and bad news. Its bad news because obviously we do not like to see the acid levels of oceans rise, but this information is also good news, because it helps others become more aware of things that need to be done to protect the environment. I think that this information is important because it is a warning of something devastating that could happen if more care isn’t taken with disposing of CO2.
I think don’t think that this article would benefit a lot of people. I think that it would benefit people who have direct authority of CO2 waste and how it is disposed of. I probably would recommend this article to some people, but not others, because it would probably get some people really stressed out, but it could help other people be more conservative in how much CO2 they produce.

Short People
We recently had our end of the year choir concert, where the top two choirs in the school performed sets of music, and all of the seniors were recognized. I am in both of the choirs that performed this past week, and while I just barely made it to the concert on time (I had an away tennis meet the same day which ended fifteen minutes before the scheduled start of the concert), both performances went pretty well.
Chamber choir is the top choir at my high school, there are just under thirty students in this choir, and the music we do in that class is often much harder than the music we do in the next highest choir (that choir has more than one hundred students).
Because of the increasingly large numbers of students allowed into the top two choirs this year, and because so many people tried out to be in a choir or in a show choir for next year, our directors have decided to make several changes to the choir program for next year.
The biggest changes being made for next year is the amount of people let into Chamber choir and into Concert choir (choir second to Chamber choir in terms of skill, and in terms of difficulty to make the group). There was a big problem faced by Concert Choir this year due to the imbalance of the group. There were probably at least twice as many sopranos than any other voice part in the choir, and there were about half as many guys than girls (altos and sopranos). In an effort to fix the blend and balance of the choir, our director is seriously thinking of cutting the number of each voice part down to twenty per section. This would mean a considerate cut in the number of students in the group this year, and a significant increase in the number of students in the intermediate choir. I feel confident that I would make Concert Choir again for next year, but I feel less certain about whether I’d make Chamber Choir again.
Our director recognizes Chamber Choir as the most select choir at our school. He feels though, that over the past few years, the choir has become less and less select. There are just under thirty students in Chamber Choir, and our director wants to redo the structure of Chamber Choir for next year so that there will only be sixteen people in the group. This means that several of the students who are members of Chamber Choir this year, will not be members next year. The soprano section will be especially competitive to be a part of ( I am a soprano).
In Chamber choir, there are currently eleven sopranos, but only four of them are seniors, which means there are seven current Chamber Choir sopranos auditioning for four openings. This concept becomes even more nerve-racking when you take into account that there are three current freshman sopranos that are apparently amazing. I feel confident about making concert choir, but after going over the numbers, I feel less confident in whether or not I will make Chamber Choir next year.
This video is of a small group singing one of the songs Chamber Choir performed at our last concert.

Tennis Team Seniors

As the school year and tennis season come to a close (we only have one regular season meet left before the state qualifying rounds begin) I have started thinking about, and in some ways dreading my final year on the tennis team.
The top six-eight players from each school are normally the players that make up the varsity lineup. This year I have been playing number one singles and doubles for my team, and the number two singles position has been played by a freshman. The rest of our varsity line-up is made entirely of seniors (with the exception of one junior, but she is graduating early…). With our last meet of the season being this Tuesday, I can’t help but feel disappointed that the girls I have been playing tennis with for the past two-three years will be graduating this year, and won’t be on the team with me next year.
Our team is currently ranked as the number three 2A team in the state (or at least I’m pretty sure we are…), and it’s the realization that we are losing four of our top six players that makes me think this is my last opportunity to make it to team state (we placed third last year, were in the top eight my freshman year-but really should have placed second at state).
It’s the realization that over half of the varsity team is graduating this year that will serve as motivation for me to work harder to make it to individual state. Because I know that this could very well be my last year competing at team state, and next year will be my last year to compete at individual state, I feel determined to work really hard over the next year in order to have an extremely successful year individually next year.

College Tennis

This week my high school tennis coach told me that a college had called him, and they were interested in recruiting me for their tennis team. I had never heard, or had hear very little about, the college that had called him, but it was still a neat feeling to know that a college coach is interested in having me on his team.
After talking to my coach (not my high school coach) about the situation, I have decided not to go to this particular college. My coach told me that the school wasn’t very good, and implied that the tennis program wouldn’t be a good fit for me either. He did tell me though, that he had talked to another coach of a different college about me, and while I haven’t decided whether or not I want to go to that particular college (it’s a local college) it was neat to hear that I was the subject of a portion of his conversation.
I know that I have wavered in my decision about whether or not I am going to play tennis in college, but after seeing how well this tennis season has been going, as of now, I plan on playing college tennis.

Senior Year

With next year being my senior year of high school, I’ve been thinking more and more lately about which classes I should take.
We signed up for classes this January, and my schedule includes: AP Literature, AP Spanish, AP Calculus, government/economics, Concert choir, AP Chemistry, Show choir, and Chamber choir (assuming I’m accepted into this group). As I look at this rigorous list of classes for next year, I can’t help but already feel overwhelmed with what lays ahead. I really don’t want to have a super busy year next year (homework-wise) because:
a.) It’s my senior year
b.) I really want to play a ton of tennis and win a state title next year
c.) I don’t like homework
I am an over-achiever. I don’t like settling for regular classes when there is an AP or advanced version I can take. But now I am seriously considering dropping a couple of my scheduled classes completely or at least taking a less rigorous course equivalent. But the question I am faced with making is which classes I should change.
I am very much tempted to take a non-AP language arts class, I feel like a big draw back to doing that is missing out on AP Literature, which is the class that graduates say helped them the most once they entered college. As much as I dislike reading and writing, it would be really nice to miss out on a couple of language arts classes in college if I were to get AP credits from taking the class in high school.
I really don’t like Spanish class, at all. The only reason I am currently taking Spanish is because I don’t want to have to take a foreign language in college (because I am told that many colleges require at least two years of a foreign language). I’m not bad at Spanish, I’ve always done pretty well in Spanish class, but it’s never really been something that I enjoy. One of my only other reasons for wanting to take AP Spanish next year is the teacher. The AP Spanish teacher is also the Spanish II teacher (I had him as a teacher last year) and he is definitely in my top three favorite teachers of all time. I really don’t like Spanish, but I really like the instructor, plus we have had conversations in which he has told me that he expects to see me in one of his AP classes my senior year.
Ever since the eighth grade I have been a part of the advanced math program, taking the advanced versions of math classes intended for the grade ahead of me. Being apart of this program for the past several years, I feel my only choice is between AP Calculus and AP Statistics. I am starting to think now that I might save myself the stress and take regular calculus instead.
Government/economics is non-negotiable; it’s a required class that I have to take before graduating.
Concert choir is also required for those that participate in show choir, so that class is also non-negotiable.
AP Chemistry is the class that I am most likely to drop completely from my schedule. After the end of this year I will have already taken four science classes (the requirement is three), I’ve already taken regular chemistry (didn’t like that at all…) and none of the other science classes are of much interest to me.
I have decided to audition for Chamber choir (I didn’t last year, but was later able to join because a member of the soprano section moved to Florida), and if I make that, then that class will meet every other day with the show choir class.
After thinking about all the choices I have in changing my schedule, I do feel more certain that I will end up changing my schedule for a less rigorous list of courses. I am still uncertain as to which classes I plan on dropping, but I feel more sure of the fact that I want to change my schedule.

Dual Meet

Yesterday was a really big match-up for tennis. We had another dual meet against both of the Iowa-City tennis teams, and it proved to be a very trying match.
After the six singles matches were over the score was three-three, so the outcome of the meet would come down to doubles. I personally lost my singles match, but was still pretty pleased with how I had played. The girl I was playing had placed third at state the previous year, and I forced our match into a tie-breaker, so the score was really close.
We ended up winning two out of the six doubles matches that day which secured an overall victory with a score of five-four. As of that day we were ranked third in the state, and that first team we played were also ranked in the top ten teams in the state.
The second team we played later that day was ranked number two in the state, so I speculated that the meet would have a very tight final score.
Like the morning match, the score after singles was three-three, so as with the morning match, the afternoon match came down to the results of the double’s matches. We ended up losing two of the three doubles matches, which made the final score of the meet four-five, our first loss of the season.
What was some-what exciting about this match-up was that even though we did lose, the probably could have won. In my doubles match we were winning four or five-one, but somehow lost our momentum and ended up losing our lead and the match seven-ten.
I’m not saying that we were the better doubles team and should have won the match, but I do think that the results of the match could have ended up differently. So if we end up playing each other again in the state-tournament, hopefully, things will turn out a little bit differently.

Audtition Week
This week has been a little more exciting than normal because it is show choir try-out week! There are two parts to a person’s show choir audition. The most important portion of the audition is vocal. Everyone auditioning for one of the three show choir groups at my high school must select a song to sing in their audition. The song doesn’t have to be long, chances are that the directors wont let you sing more than a fourth of it anyways, but even though it’s the shortest portion of the audition, it’s also the most important. My vocal audition is tonight and I have selected “Voi Che Sapete” (I may have butchered the spelling of that…) as my try out piece.
The second and third most important factors in determining who will make one of the groups is based upon teacher recommendations and grades.
The fourth factor in determining if someone is cast in a group or not is the dance audition. In this audition, the choreographer of our varsity show choir comes in and teaches a short, but difficult, dance. Everyone is divided into groups of five or six, and then the groups come in one by one and perform the dance twice for the choreographer, and the three directors of each of the show choirs. Each person is evaluated and then the next group comes in, thus continuing the cycle.
Even though it causes a lot of stress, I like audition week. I don’t like singing in front of people, but my audition is the time when I am able to show the choir directors how I really sound. And though the dance audition is always hard, it’s also a lot of fun, especially because the choreographer usually makes the dance to a popular song. The only bad thing about the audition process is waiting for the group lists to be posted. We tried out the week of April 26, but the lists won’t be posted until May 22.

Rain Check

Over the weekend we were scheduled to play in a dual meet against two of the local high schools (dual meet just means playing two schools in one day). Due to weather we had to postpone the start of our first meet but ended up winning the meet seven-two. Our second meet started later than normal because of the postponements earlier in the day, and after starting the meet we eventually had to stop and reschedule the rest of the match for a later day because it started raining again.
When we left off with our second match, the meet score was one-one (we had both lost one and won one singles match). I was up in my match nine-zero, our number three player was losing her match three-seven, our number four player was down five-six, and our number five player was winning seven-four or five. Needless to say, the team we are playing is about the same skill level as us. We are finishing the meet tonight (unless it rains… again) and though I hope we win this meet, at this point, it really could go either way.

The Pan Flute
Here is a brief explanation of how my pan flute works (or at least how i think it works). I'm still a little confused on the whole wavelength thing, but I feel like i did a pretty decent job of faking it in this explanation.
I constructed my musical instrument (a modified version of the Pan Flute) by cutting various lengths of PVC piping, duct taping them together and blocking off the bottom end of each piece of piping with a ball of clay.
I started out cutting five different lengths of .5” in diameter of PVC piping. The approximate lengths I used for each piece of piping respectively were 9.5”, 8.5”, 7.5”, 7”, and 6.5”. I then sanded the ends of each pipe, laid the pipes out so that the tops of each pipe is aligned with each other while the bottoms end staggered, and then taped the pipes together.
After constructing my pan flute thus far, I struggled with finding a material to block off the bottom end of each pipe. I was able to produce a pitch with each tube when I placed the palm of my hand on the end of each tube separately, but could not find a material that was capable of reversing the travel of the sound waves. I finally found the solution to this problem while looking online.
The answer was clay. All I had to do to block of the end of each pipe, thus enabling myself to create a pitch, was to place a wad of clay at the bottom opening of each tube. This solved my problem, and I was able to create five different pitches from the five pipes without placing my hand over the opening of each one.
The physics behind this instrument can be identified through the principles displayed by wavelengths traveling through a pipe with one closed end and one open end (the end with the clay being the closed end). Because one of the ends of the pipe is open and one is closed, the open end is an anti node and the closed end is a node. Because one end is a node, and the other end of the pipe is an antinode, only odd numbered harmonics are capable of being produced within the pan flute. As air is blown across the top of an individual pipe, the air particles travel down the column as a wavelength and as they meet the clay at the end of the pipe, are reflected back out the pipe, thus creating a sound.
The differences heard in the different pitches of each pipe can be understood through the definition of frequency. Frequency is defined as “the number of cycles or vibrations per unit of time; also the number of waves produced per unit of time” (Serway, Raymond A. and Jerry S. Faughn 954). As the frequency is increased the pitch becomes higher. In my pan flute, the shorter pipes have higher pitches than the longer pipes. Keeping in mind the definition of “frequency” we know that this is because a cycle of vibrations will complete itself faster in a shorter pipe than in a longer pipe. Thus, shorter pipes create higher pitched sound.

The differences heard in the different pitches of each pipe can be understood through the definition of frequency. Frequency is defined as “the number of cycles or vibrations per unit of time; also the number of waves produced per unit of time” (Serway, Raymond A. and Jerry S. Faughn 954). As the frequency is increased the pitch becomes higher. In my pan flute, the shorter pipes have higher pitches than the longer pipes. Keeping in mind the definition of “frequency” we know that this is because a cycle of vibrations will complete itself faster in a shorter pipe than in a longer pipe. Thus, shorter pipes create higher pitched sound.

Rain, Rain Go Away...

Yesterday our tennis team had another dual meet (play one team in the morning and another team in the afternoon). We had to postpone the start of our first meet due to the rain, but ended up winning the meet seven to two.
After we played the first meet, most of the team stopped at Panera for lunch. I ordered a soup and sandwich, but later regretted it. The table we sat at was a smaller-sized table and my plate wasn’t fully situated on the table, so that part of my plate was hanging over the edge of the table. I accidentally pushed down on the part of the plate hanging over the edge of the table and spilled soup all over my tennis dress! It was a huge mess! Fortunately the meet was in town and one of my teammates was able to bring the black tennis skirt we used as a uniform last year, and I just used that and this year’s t-shirt for our second meet.
Prior to the start of my match, I was very nervous. I always get more nervous than usual before playing this particular school, and I wasn’t really sure what to expect walking out onto the court. I had played this particular girl before and both of us had wins over the other. My coach and I had talked strategy over this particular player a couple nights prior to the meet, and so I wasn’t going into the meet totally unprepared. All the singles players started their matches and mine was going really well! Before we had to postpone the rest of the match until Monday, I was winning the match 9-0 (we play a ten game pro set). We are going to finish the meet tomorrow, and I pray that God will give me the focus I need to win the match!

Pan Flute
¬¬ I blogged awhile ago about a physics project where I was assigned to make a musical instrument that is capable of playing five different notes in a scale. We are also required to identify what makes our instrument capable of creating sound, and are also supposed to play a song in front of the class. Well, the project was assigned about three weeks ago, it’s due tomorrow, I about half way done with it.
I have the actual instrument made (I found instructions online for making a PVC pan flute) but have yet to pick out a “recital” piece for the class, or figure out all the physics properties involved that causes my instrument to create sound! This is such a frustrating project for me! It was assigned by our student teacher (I’m pretty sure our regular teacher doesn’t assign this project) and so I get really annoyed knowing that if we didn’t have a student teacher I wouldn’t be stuck doing this stupid project! Spring, with tennis season, is probably the most stressful season of the year, and having to do this project is has just made it more stressful.
Following directions I found online, I made my pan flute by cutting a ½” in diameter piece of PVC piping into various lengths (longer lengths create lower notes, and shorter lengths create higher pitched notes). Then I laid the pipes together, aligning the tops of each pipe with each other, and then duct taped them together. Then I realized that the pipes would only create sound if I blocked off the end of the tube with my hand. This made sense, since the air I blew into the top of the tube needed something to bounce off of (my hand).
The problem was, I couldn’t very well keep one end of each pipe covered with my hand and play it at the same time! It took a little while to find something that would block off the end of the tube and still produce noise when I blew into the top end of the pipe. I tried plastic wrap, a cotton ball, and even melting wax from a candle to cover up the end, but nothing worked. I eventually found the answer online: clay. So I blocked off the end of each pipe with a clump of clay, which allows me to blow air into the top which creates a pitch.
Now all I have to do is figure out why my instrument is capable of producing pitch, and figure out what song to perform for our physics class concert: “Physics Rocks!”

The Unhappy Hippo

I wrote this poem, and though it may seem a bit random, I felt the need to share it with the world.
The Unhappy Hippo
Once there was a hippo,
he loved to dance and play,
but in his heart, he was sad,
because he was all gray.
You see he desired uniqueness,
to be different from the rest,
so because he looked like all the others
he longed for some zest.
So he dyed his skin bright yellow,
and he loved it to no end,
but then the others followed suit,
because the others liked this trend.

Ursula

I think that for his job, my dad has to have a certain number of hours of conferences in order to maintain his medical license. So every now and then, my dad travels to other states to complete the required amount of conference hours. Usually my dad travels to warmer places like Florida or Texas, so that he can go golfing when he doesn’t have to go to a meeting. But I remember from when I was younger that my dad would go to colder places, like Colorado, so that he could go skiing. On at least one of these occasions, my dad took my older sister, Bethany with him, and she would sit and color during the meetings and then go skiing with my dad afterwards (she was about ten at the time).
This happened such a long time ago, that I don’t remember all of the details, but I do remember that when she left for Colorado, she left me to baby sit her stuffed animal, Ursula. I was probably, four, five, or six at the time, and I was pretty excited to be entrusted with the responsibility of taking care of this little green teddy bear wearing a sunflower dress. I’m not certain, but I think that when my job as Ursula’s care taker had just started, I stayed with Ursula, and would take her with me everywhere I went. But as the excitement of this new job started to wear off, I think I became less enthusiastic about watching Ursula. Don’t get me wrong, I still liked “baby sitting” her, but I think I became less devoted to taking her with me everywhere I went. That’s probably why I would occasionally misplace her.
I vaguely remember that one time, I forgot the last place I had put Ursula, and I became panicked because I had lost her. Eventually though, I did find her, but I think that the prospect of losing probably my sister’s favorite stuffed animal scared me into being more responsible (at least for a while) with Ursula.
I think that the reason I was so excited about having this “baby sitting” job, was because since I was so young, I never really got the chance to be the “adult” and take care of someone else. So having the opportunity to actually be the one to take care of someone (or in this case, something) else made me feel important and more grown up, and I think that that was probably one of the reasons why I enjoyed the job of baby sitting Ursula, the green teddy bear.
I can see similar qualities in regards towards my older brother Ben, and our new puppy Cooper. Ben is twenty-three years old, but has lived with Down’s Syndrome ever since he was born. We have had Cooper for almost two weeks now, and like me and my experience with baby sitting Ursula, I can see Ben enjoying taking care of our new little puppy. I think he likes to feel like he’s in charge of as many situations as possible, because he’s so used to being looked after, I imagine that its really refreshing for him to be the one responsible for someone else.

Yesterday was our second tennis tournament of the year, and overall I am very happy with the results. The Tournament is comprised of four high schools, John, F. Kennedy, Decorah, Ottumwa, and Columbus high school. This is another tournament that we go to every year, and is usually a pretty competitive day of tennis.
With the three singles matches, and the three doubles matches I played yesterday, I played a total of seventy-two games of tennis, and needless to say, my body can sure feel the after effects of such a strenuous day today.
The way school-sponsored tournaments work is all the number one seeds from one school play all the other one seeds from every other school in attendance, same with the two seed, the three seed, and so on. I was playing as the number one player from Kennedy, and had, prior to that day, played each number one seed from all the other schools at the tournament.
I was nervous for this tournament, because though I had played all three of the other girls before, I had only beaten one of them. I had played the girls from Decorah and Ottumwa at the tournament my school had hosted before, and the girl from Columbus the previous year at the same tournament.
My first round match was against the girl from Ottumwa. She was one out of the three that I had already beaten that same year, and the final score of that match was eleven to one (we played a total of twelve games). My second match was against the Columbus girl, and was the match I had been worried the most about.
I was really anxious walking out onto the court. I had lost to this same girl last year, I think the score was somewhere around four seven, and I really didn’t know what to expect from her. The match got off to a good start, and I ended up beating her eleven to one. Winning this match really made me realize that I have improved since last year. My coach has told me that I have improved greatly over the last six months, but I’m not sure I really believed him until I beat the Columbus girl.
My last singles match of the day was to the left-handed Decorah girl whom I lost to in a tiebreaker the previous week. I felt confident going into that match since I had just played really well against the Columbus girl, and because I was going into this match up with a different strategy than I had the previous week. Well, with the help of God, and the fact that I was playing a smarter game than I had the previous week, I was able to win my final match seven to five.
So this weekend has been a pretty good weekend for me in terms of tennis. I feel more confident in myself as a competitor and feel myself leaning more and more towards playing college tennis.

Cooper

We have had our new puppy, whom we decided to name Cooper, for about a week, and have all gotten somewhat used to having a little dog roaming the house.
Cooper now is about eight years old, and is still just as little as could be. Im trying to enjoy having such a little dog around, because I know it won’t last forever, in a couple months he’ll probably be too big to hold!
While he has had several accidents in the house, we think he may have finally be house-broken. We trained him to ring a bell hanging from a door knob when he needs to go outside, and he has successfully used this system on a couple different occasions.
I never realized how unbalanced and weak little puppies could be! Cooper is always sliding all over our tile and wood floors. He is not big enough to make it up or down the stairs, but it’s really funny to watch him try!
Cooper likes to chase our seven-year old toy poodle-bichon mix, Sammy, but Sammy will have nothing to do with Cooper. I find it funny that Sammy is being grouchy and anti-social to a dog that will grow to be several times larger than him!
At this point, our only concern about Cooper is the fact that he keeps gnawing on us. We are not sure if he is biting because he is still teething, or if he is going to grow into an aggressive dog. I really hope that he won’t develop a habit of biting people. While Sammy is incredibly anti-social outside of our family, I absolutely without a doubt trust him around younger kids, because even when he is being bullied by toddlers, I’ve never seen him bite one.
Overall I am really excited about having a puppy around the house! he is really cute, and a lot of fun to watch, I just hope he is an even better dog once he gets bigger!

Physics Rocks!
Recently in my physics class, we were assigned to design our own musical instruments that can play at least five notes in a scale. The assignment was cleverly titles "Physics Rocks!" and we are to build a creative instrument that we should be able to play in front of the class, and write a paper about the physics principles that allow it to create sound. After getting over the initial hilarity of this concept, I realized just how hard this project is going to be. Our instruments are going to be graded on how creative they are, and while this project sounds fun, there’s only so much a high school student can do that hasn’t been done before.
I have tried thinking of unique ways to make sounds, but I keep coming up with simple solutions: drum-like instruments along with xylophones and bells. According to my student teacher, Spock (his name isn’t Spock, but he has a strong resemblance to the leading Vulcan in “Star Trek” the movie), instruments like these most likely won’t receive “A’s” because they are not creative enough.
Here are some pictures of “homemade” instruments I found online.

I think that this "instrument" is supposed to be a guitar-like instrument. I think my instrument may need to be a bit more elaborate.

This "Boxbass" instrument seems to be a bit more elaborate than the previous instrument. I think that the "Boxbass" looks really intresting, and really makes me rethinkg whether I should try making a percussion instrument, or try doing an elaborate stringed instrument like this one.

I was also thinking of trying an instrument like this, where there are mallot-like extensions that when raise, they drop and hit a surface to make a sound.
Looking online has given me some more ideas for this wacky project, and so now I have a little less than two weeks to come up with something brilliant!
