Who Poisoned Buzz Lightyear?
By: Michaela EllisSlide2
Introduction
A
couple of days ago we found out that Buzz
Lightyear
was poisoned. But we don’t know who it was. It could have been anyone. We have a list of suspects that were at the dinner party and they are the Wicked Witch, Snow White, Daffy Duck, Shrek, Dorothy, Princess
Leia
, Harry Potter, Jimmy Neutron, Icky Vicky, Darth Vader, Lord
Voldemort
, Goofy, Ariel,
Ursala
, Donkey, Prince Charming, Nancy Drew,
SpongBob
, Dora, and Luke Skywalker. As of now a group of highly developed students have been working on this problem.Slide3
Hypothesis
These
students believe if Buzz
Lightyear
was poisoned by these things in the crime scene, then it should have been Jimmy Neutron because the things he brought matched the things found at the crime scene matched.Slide4

Drink Procedures
Test the drinks density by putting the drink inside a graduated cylinder with water and seeing if the water rises. If it does then the drink is more dense than water, and if it sinks then the drink is less dense.
Look at the drink and determine what color it is.
Find if the drink is conductive or not with the conductivity meter and write down how conductive the drink is.
Waft the drink and observe how it smells and write it down.
Take a match and drop it into each drink and see if the drink can with stand a flame or hold one.
Test the reactivity by dropping baking soda in the drink and seeing if the drink fizzes or bubbles or reacts and write it down.
Write all the information found on tables to help keep track of the data. Slide7
Wrap procedures
Determine
malleabillity
by trying to bend the wrap. If it bends then it is malleable.
Determine if the wrap is conductive or not with the conductivity meter.
Look at the wrap and determine what color it is.
Find the density by finding the volume with the graduated cylinder and the weight in grams and divide grams by milliliters.
Next test the reactivity with hydrochloric acid. But
Be Careful
this acid will eat your skin and irritate the eyes and nose.Slide8
Powder procedures
Test the solubility by taking the dropper and dropping the water inside the powder. If the powder dissolves then it is soluble.
Test the conductivity after you test solubility so you can get better results by sticking conductivity meter inside the watery powder.
Test if the powder can melt by putting the powder on a hot plate heater.
Test the reactivity by putting vinegar inside the powders. You have to do this with new powder not watery powder from the solubility test.
Test the flammability by dropping a match into the powder and see if it can with stand or hold a flame.Slide9
Hot dog procedures
Test the conductivity by sticking the conductivity meter ends inside the meaty part of the hot dog.
Find the density by finding the volume with the graduated cylinder and the weight in grams and divide grams by milliliters.
Before squeezing the hot dog find the mass by weighing it on a balance beam to find the mass pre-squeezed.
After squeezing the hot dog get the mass by weighing the hot dog on the balance beam to find the mass post-squeezed.
Test the reactivity by dropping ascorbic acid on the hot dogs with the eye dropper.
Do any of these procedures even in the drinks, wraps, powder, and hot dogs in the
forcets

Conclusion
In
conclusion, the students hypothesis was wrong. They came close to the answer but were off by a couple of suspects. The actual persecutor was SpongeBob. The data showed this conclusion and proved them wrong. After testing all of the crime scene products found they found out it was indeed SpongeBob. If even one of the crime scene products would have changed the persecutor could have been someone else.
There
were however some limitations in the students equipment. They didn’t always have what equipment they needed or could have used. This means the data could be slightly different if you use something else to prove this idea. Also the hot dogs we used were cut up into different lengths slightly so the data could possibly be off slightly.
