Who killed buzz light year?

● Woody and Buzz have a party and invite a bunch of people and while they’re partying, Buzz is poisoned and he collapsed to the ground then the area is roped off and there is many clues to who is the culprit so Woody decides to find the culprit and bring him/her to justice while Buzz is in the hospital!!!

Lab Report

Drink LabOne of the clues found at the crime scene was a mysterious clear liquid and the detective narrows it down to 6 liquids water,salt water, vinegar, alcohol, grape drink, lemonade and pulp.

DRINK LAB: Procedures & Material

● First you must put your googles

● For color you need to stare at the beaker

● To measure density you must compare to water a graduated cylinder

● Conductivity is measure by a electric meter

● Do not directly inhale the fumes of the sample only wift it

● To test flammability you must let the teacher do the experiment

● To test reactivity you must use sodium bicarbonate to test if there is a reaction

● Well plate● Beakers, eye

droppers● Sodium bicarbonate,

conductivity meter● Balance, graduated

Wrap lab

Another of the clues was a wrap for the food that that was similar to 6

others ; plastic, aluminum, zinc, copper, iron, and sulfur

Wrap Lab: Procedures & Materials ● Put on goggles

● See if its possible to bend metal samples

● Check electric composition by using conductivity meter

● Drop metal into graduated cylinder

● Look at the appearance

● Put metal in the well plate and drop the acid without touching

● Graduated cylinder,conductivity meter

● Goggles,acid,well plate,eyedroppers

Wrap Conductivity Malleable Density Appearance Reactivity

Plastic low yes <1.00 Clear or different color s

Zinc high yes >1.00 Shiny grey no

Aluminum high yes >1.00 Shiny grey no

Copper high yes >1.00 Dark brown orange

Slight discoloration

Iron high yes >1.00 Shiny grey Little bubbles possibly erodind

Sulfur low no >1.00 yellow no

Crime scene liquid

high yes >1.00 silver ?

Powder Lab

The next clue was also at the scene of the crime it was a strange white powder 6 different powders could possibly be the same as the crime scene liquid.

Powder Lab: Procedures & Materials

● Must put goggles on

● Put powder in beaker then put water to see the solubility

● Check electric composition by using conductivity meter

● Allow teacher to do the flammability experiment

● Put the powder in the well plate then add the vinegar to the powder

● The last experiment will be up to the teacher; the heat plate is at a constant temperature letting it melt or burn DO NOT TOUCH!!!

● Well plate,heating plate,vinegar

● beaker,eye droppers,matches, conductivity meter, stirring rod

Hot Dog

● The final, last clue at the scene was a half eaten hot-dog laying on the ground there is only 3 possible samples

Hot Dog: Procedures & Materials ● Put goggles on

● Put pre-squeeze hot dog on the balance to measure mass

● Put post-squeeze hot dog on the balance to measure mass

● Check electric composition by using conductivity meter

● Put hot dog on balance to get mass

● Put hot dog on well plate and put iodine for reaction

● Goggles, well plate, balance

● eye droppers, fist, iodine, acid

Crime scene liquid

Very high 10 grams 10 grams Turned Dark

Hypothesis & Conclusion● The hypothesis was : If the culprit was Ariel then

she is responsible for the crime because she has most evidence on her.

● In conclusion the hypothesis was mostly likely correct, Ariel is the most likely suspect
