__﻿Who Poisoned Buzz Lightyear!?: The Investigation Begins Now.__ BY: Justin Harrison
====Introduction: One day on a cooking show Woody and Buzz started, they were having their viewers grill their own hot dogs on wraps, make their own desserts, and powders and give them to Buzz for tasting. On the day of taste test, Buzz was poisoned by one of the foods! We as the investigators must and will solve this crime and find out, who did it. The information we were able to gather so far was the following 20 suspects, along with the drink, wrap, powder, and hot dog they used shown in the following chart:==== The purpose of the information gathered here is to find out the different physical and chemical proporties of the items that may have contributed to the poisoning. But even with the information we've gathered, it will take us a while until we find out: who poisoned Buzz Lightyear!

Hypothesis: Darth Vader was probably the culprit because when looking at the crime scene, the powder was in the drink with no reaction to the drink, so the drink may be either water or salt water that just being an inference. The hot dog was a pretty light color, so it may be fat free or possibly light pork. Also when looking at the wrap, it's possible that it was aluminum since it looks like it could be bent easily.

Materials: The materials needed for these test are the following: hand lenses, a triple beam balance, a well plate, beakers, eye droppers, sodium bircarbonate, a graduated cylinder, HCI( hydrochloric acid), goggles, forceps, spoons, stirring rods, matches, paper cups, hot plates, iodine, lemonade, water, saltwater, vinegar, grape drink, alcohol, plastic, aluminum, zinc, copper, iron, sulfur, ascorbic acid, surcrose, baking soda, sodium chloride, sodium polyacrylate, pork, light pork, and fat free hot dogs.

Drinks:
1. To test conductivity in the drinks, students must stick the rods of a conductivity meter in the drink and record the readings of the light patterns (repeat with each drink). 2. To test density in the drinks, students must pour the drink into a graduated cylinder with water and see if the floats or sinks in the water (repeat with each drink). 3. To find the color of each drink, students really just have to observe the each drink's color appearance. 4. To test the optical properties of the drinks, students must observe each drink and see if it's transparent, translucent, or opaque. 5. To test flammability, students must light a small fire(preferably a match) then skim the match across the surface of the drinks to if the surfaces on the drink. 6. To test reactivity of the drinks, with Sodium Bicarbonate, students must pour a teaspoon of Sodium Bicarbonate on each drink and observe the reactions.

Wraps:
1. To test the texture of each drink, students must describe what they feel when they touch each wrap. 2. To test conductivity, students have to touch a each wrap with the rods of a conductivity meter and read the light patterns and record the readings (make sure the rods aren't touching). 3. To test malleability, students must take each metal and see if it is bendable. 4. To test the luster, students must observe each wrap and see if it's either shiny or dull. 5. To test reactivity in the wraps, students have to take an eye dropper with hydrochloric acid and drop about 1 to 3 drops of each wrap see the reactions.

Powders:
1. To test solubility, students must take an eye dropper with water and drop about 2 to 3 drops of water and observe if the powder dissolved or not. 2. To test conductivity, students must first have the powder in it's solution form. Then stick the rods of a conductivity meter in the solution and observe the readings (make sure the rods aren't touching each other). 3. To test melting, students must put the powder on a heated steel plate and have each one at the same temperature. Observe if the powder's melt, burn, is unaffected, etc. 4. To test reactivity, in a well plate, put each of the powders. Then, in an eye dropper fill it with vinegar. Then drop about 2 to 3 drops of vinegar on each powder and observe the reactions. 5. To test flammability, students must light a match with a small fire and skim the surface of the powder and see if it lights on fire, is burned, etc.

Hot Dogs:
1. To test the pre-squeeze mass, students must without squeezing the hot dogs place each hot dog seperatly on a triple beam balance, measure until equally balanced, then record the mass. 2. To test the conductivity, students must without squeezing the hot dogs place the a conductivity meter's rods into the meat part of the hot dog(not through the skin) and record the readings (repeat with each hot dog; make sure the rods aren't touching). 3. To test density, without squeezing the hot dog at all during this test, students must first find the mass of each hot dog which should have been done already from step one and find the volume of each hot dog by putting each hot dog in a graduated cylinder with water and record how much the water rises. Then do mass divided by volume. 4. To test reactivity, students must without squeezing the hot dogs take an eye dropper with iodine and drop 2 drops of iodine on the meat part of each hot dog, then record the reactions. 5. To test post- squeeze mass, students must first squeeze each hot dogs until they're in small pieces. Then seperatly place each piece of the one type of hot dog on a triple beam balance,and then record the mass.

Conclusion: From the information gathered in these labs, it seems that this scientist's hypothesis was disproved. The theory that Darth Vader was the one who poisoned Buzz Lightyeat was wrong. The thing is, this hypothesis was way off because for one, Darth Vader's drink was salt water and when looking at the lab, the powder in the drink wasn't dissolved when salt water has dissolved salt in it. And second of all, the hot dog at the scene was a dark color where fat free has a light color to it. There were no patterns regarding this hypothesis. Because most of reactive materials were dangerous, there was a certain amount of each one that the scientists could use in the experiment such as one to three drops of certain liquids. Some flaws that will be corrected in the future is that when taking the mass of something in pieces, make sure to get all the pieces (even the fairly small ones). The experiments that may develop from this one is to see what the scientists learn in this experiment. The students have elimanated any chance of the culprit being Daffy Duck, Harry Potter, Goofy, Donkey, or Ursala however, from the information gathered here, it seems that the person that poisoned Buzz Lightyear is Ariel.

Essay: Do you know how easy it is to create your own instrument and your very own dream concert hall, easy as pie is how easy it was because I was able to do both. The name of my original instrument is the bumblebee since it sounds almost exactly like a bumblebee. I got the idea since I thought about how bees had pretty good pitches when they buzz. The closest family the bumblebee would fall under would be the wind family. The bumblebee is very light, and the pitch would probably be low, so on a piece of music, it would have a bass clef. The resonance and the acoustics go perfectly with the instrument. Tone is a bit rusty, but is still good with the way the bumblebee was built. For the next two paragraphs, I will explain the materials and proceduces put into this project. The materials used for this was six cardboard paper towel rolls and one cardboard toilet paper roll. Where I found the needed materials were right here in my very own home. The materials were mainly cardboard tubes that came from paper rolls. The material and shape was what made the instrument so phenomenal. When I made my instrument, I had to make sure that all of the air was being channeled frm one end to the other. So what I did first was tape a diagonal short tube that wa acting as the mouthpiece to one of the longer tubes pointing down. Then I cut four holes in another long, horizontal tube in order to attach the mouth part and the three opening tubes which is also the main tube. I also had to tape two of the already open holes at the ends of the main tube so air wouldn't escape through there. My father helped me with an idea of the shape and the cutting and openings. All of the parts however were technically factory-made. Problems I had was making sure air didn't escape from where it wasn't suppose to, so I had to tape those areas. Now I'll explain how to play the bumblebee. Playing the bumblebee is like playing a brass instrument, you just need to vibrate your lips, and you also need to have good air control. To change the pitch, you must alternate how much air you blow and you mouth's arrangement. You can also change the position of the bumblebee so you can even play it upside-down (to the right, to the left, etc.), however, the sound doesn't change. You can tune this instrument by simply using a tuner or by making the matching the pitch of another instrument. The waves traveled by diagonally bouncing off of the curved edges at the perfect time that creates a constructive interference, amplifying the sound greatly. At the end of the project, I was so proud of myself that I didn't just create an instrument, but a sign of infinite possibilities. While my father and I was making the bumblebee, he said that making a musicial sound come out of it was impossible, but after making a sound come out of something as simple as this, I was filled with joy with a lesson learned that anything was possible with enough effort. What I really liked about this project was that I could express myself in an artistic and musicial way. I wouldn't change a thing about the bumblebee, it is perfect the way it is.
