Who poisoned Buzz Light Year? **Intro:** One the very first day that the detectives went to the crime scene they observed the scene and jot down notes and their observations. Their objective was to find out who poisoned Buzz Light Year? The detectors created a suspect list and will conduct different experiments to determine who poisoned Buzz Light Year. On the scene there was powder, a piece of meat, a piece of wrap, and a drink. The scientists will conduct an experiment for each of the categories with the possible outcomes. In the end they will see how the outcomes match with the suspects and the one that does is the one that poisoned Buzz Light Year. **Miss Smarty's Hypothesis:** If Dora was the one that poisoned Buzz Light Year then baking soda,zinc,light pork hot dog,or salt water poisoned Buzz Light Year. ** Materials Miss Smarty Used: ** Some of the materials that the scientist used were… Well plate Beaker Eye dropper Conductivity meter Graduated cylinder Goggles Tweezers Magnifying glass Paper towels Sodium by Carbohydrate matches pure water alcohol salt water vinegar grape drink lemonade with pulp pork hot dog light pork hot dog 98% hot dog sucrose sodium poly. sodium chloride asorbic acid baking soda plastic wrap aluminum zinc copper iron sulfur

**Procedures:** There were different procedures that each scientist had to go through for each of the labs… Drinks: For the drinks the scientists preformed a density test, color test, optical property test, conductivity test, flammability test and reactivity test. For density they calculated mass divided by the volume. For color they determined the color of it (ex: was it dark, light, shaded, exc.) Next for optical properties we had to determine if it was oblige or transparent. For conductivity they used the conductivity meter, put the two wires on the object and saw if the red and green lights went on. For the flammability test the teacher fired the objects to determine if they are flammable or not. Finally for the reactivity test the students mixed the different powders to see if they dissolved. Wraps: For the wrap tests we determined the luster, malleability, conductivity, density and reactivity. First the scientists preformed the luster test, they determined if the object was shiny or dull. Next the scientists preformed the malleability test, they determined if the wraps were able to bend or not. Then they did the conductivity test, like the drinks lab they used the conductivity meter. Finally they preformed the density and reactivity labs. For the density, they found the mass and volume and divided them to find out the density. For the reactivity test they put different liquids on them to see if they reacted with one another. did the powder labs... Powders: For the powders the scientists preformed the solubility, conductivity, melting, reactivity, and flammability labs. For the solubility lab they put water in each of the powders to see if they dissolved. Next they preformed the conductivity test with the conductivity meter. After that they preformed the melting test, they observed each of the powders while they were heating on heaters. Then they did the reactivity test, for this test they mixed each powder with vinegar to see if it reacted with the vinegar. Finally, the flammability lab- each of the powders was put in a cup and fire was added that’s how we determined if it was flammable of not. Hot Dogs: For each hot dog the scientists determined the color, dencity, mass presqueeze, mass post squeeze and it’s reactivity. For the color test the scientists determined the color of the hot dog. Each group of scientists were given a small piece of hot dog (about ¼) and also had to determine the dencity, which is mass devided by volume. After that they worked on the mass pre-squeeze and then did the mass post-squeeze. The mass preesqize is the hot dogs weight before the post-squeeze. The post squizee is when one scientist from the group squeezed out everything from inside the hot dog, and then found its mass. Finally the reactivity test was perfomed when a drop of liquid was put on the hot dog and then they had to observe the change in color, temperature, exc.

My hypothesis was If Dora was the one that poisoned Buzz Light Year then baking soda,zinc,light pork hot dog,or salt water poisoned Buzz Light Year. After all the experiments and labs preformed ,my hypthesis was proved to be wrong. All the data collected my the scientists prove my hypothesis wrong. The scentist had to make charts and perform different experiment to find out who poisoned buzz lighyear. The scientist came to a conclusion that Sponge Bob poisoned buzz lightyear.
 * Conclusion:**

Some things that proved my hypothesis wrong was the wrap lab. The crime scene lab is malleable which eliminates sulfur. It is also shiny which also eliminates plastic. The density is .1g/ml and when it reacts there is some bubbling, so the crime scene wrap must be the iron. This is what the scientist has done for each of the labs to narrow it down to the crime scene drink,wrap,hot dog, and powder. After all of the crime scenes were found then there was a suspect list and the scientist had to narrow it down to the right suspect based on the tests performed.
