IKIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Buzz Light year Poisoning Case The Buzz Light year mystery is a poisoning of Buzz and four clues were left behind. A Strange white powder, a clear liquid in a beaker, a piece of a hot dog, and a metal like wrap. You will have to make several experiments to try to figure out what the materials are and match them with what the victims were carrying. __Hypothesis: __ If the materials/evidence left behind was water, iron, sucrose, and fat free pork, then Shrek poisoned Buzz Light year because Shrek was the only known suspect to bring those material. __Materials: __ **The Testing Materials-** **The Materials Tested-**

Procedure: (Copy down the following charts)

** Procedures for Liquids **
 * 1) **Conductivity**
 * 2) Place the two tips of the conductivity meter into the liquid.
 * 3) Record the conductivity.
 * 4) Repeat with the rest of the liquids.
 * 5) **Density**
 * 6) Fill a graduated cylinder about half way with pure water.
 * 7) Using the eye dropper, drip one other liquid into the graduated cylinder and write down if it sinks or floats.
 * 8) Empty out the graduated cylinder.
 * 9) Repeat until all the liquids have been used.
 * 10) **Reactivity**
 * 11) Using the eye dropper, drip one liquid into the well plate.
 * 12) Using a different or cleaned eyedropper, drip Na HCO3 into the liquid.
 * 13) Observe and record the reaction of the two liquids.
 * 14) Repeat with the rest of the liquids.
 * 15) **Odor**
 * 16) Hold liquid about one foot from your nose.
 * 17) With your hand, waif the odor towards your nose
 * 18) Record the smell as best as you can.
 * 19) Repeat with the rest of the liquids.
 * 20) **Color**
 * 21) Look at liquid
 * 22) Record the color.
 * 23) Repeat with the rest of the liquids.
 * 24) **Flammability**
 * 25) Place liquid into a glass beaker
 * 26) Light match on fire and drop in liquid
 * 27) Observe and record what occurs.
 * 28) Repeat with the rest of the liquids.

** Procedure for Wraps **
 * 1) **Color/Luster**
 * 2) Look at the wrap and record color.
 * 3) Look at the wrap and record if it's shiny or dull
 * 4) **Conductivity**
 * 5) Place the two tips of the conductivity meter onto the wrap.
 * 6) Record the conductivity.
 * 7) Repeat with the rest of the wraps.
 * 8) **Malleable**
 * 9) Pick up a wrap and try to bend it, if it bends without breaking, than it's malleable.
 * 10) Record your findings.
 * 11) Repeat with the rest of the wraps.
 * 12) **Reactivity**
 * 13) Place the wrap into the well plate.
 * 14) Using an eyedropper, drip three drips of HCI onto the wrap.
 * 15) Observe and record the reaction of the HCI and the wrap.
 * 16) Repeat with the rest of the wraps.
 * 17) **Density**
 * 18) Using the triple beam balance, measure the mass of the wrap.
 * 19) Now fill a graduated cylinder about half way with water and record how many ml are there.
 * 20) Drop the same wrap you found the mass with into the graduated cylinder and record the amount of water displaced.
 * 21) Repeat with the rest of the wraps.

** Procedures for Hot Dogs **
 * 1) **Pre-Squeezed Mass**
 * 2) Using the Triple beam balance, weigh and record the weight of the hot dog.
 * 3) Repeat with the rest of the hot dogs.
 * 4) **Post-squeezed Mass**
 * 5) Using the exact hot dog you used for the pre-squeeze, place it in between two paper towels
 * 6) Using a fair amount of strength, squeeze the hot dog until no more oils are coming out
 * 7) Scrape off whats left of the hot dog from the paper towel onto the triple beam balance and record the data.
 * 8) Repeat with the rest of the hot dogs.
 * 9) **Reactivity**
 * 10) Place the hot dog into the well plate.
 * 11) Using an eyedropper, drip Iodine onto the hot dog.
 * 12) Observe and record the reaction of the Iodine and the hot dog.
 * 13) Repeat with the rest of the hot dogs.
 * 14) **Density**
 * 15) Using the triple beam balance, measure the mass of the hot dog.
 * 16) Now fill a graduated cylinder about half way with water and record how many ml are there.
 * 17) Drop the same hot dog you found the mass with into the graduated cylinder and record the amount of water displaced.
 * 18) Repeat with the rest of the hot dogs.
 * 19) **Conductivity**
 * 20) Place the two tips of the conductivity meter into the hot dog.
 * 21) Record the conductivity.
 * 22) Repeat with the rest of the hot dogs.

** Procedures for Powders ** Data:
 * 1) **Melting**
 * 2) Place powder on heating tray.
 * 3) Record if it melts or not.
 * 4) Repeat with the rest of the powders.
 * 5) **Solubility**
 * 6) Fill a beaker with pure water.
 * 7) Using the spoon, pour powder into the beaker full with water.
 * 8) Mix with the stirring rod for at least one minute.
 * 9) Record if it dissolves.
 * 10) Repeat with the rest of the powders.
 * 11) **Reactivity**
 * 12) Place the powder into a well plate.
 * 13) Using the eye dropper, drip vinegar onto the powder.
 * 14) Observe what occurs.
 * 15) Repeat with the rest of the powders.
 * 16) **Flammability**
 * 17) Place powder into a glass beaker.
 * 18) Light match on fire and drop on powder.
 * 19) Observe and record what occurs.
 * 20) Repeat with the rest of the powders.
 * 21) **Conductivity**
 * 22) Place the two tips of the conductivity meter into the powder.
 * 23) Record the conductivity.
 * 24) Repeat with the rest of the powders.

Conclusion: Once again, the hypothesis was that if the materials/evidence left behind was water, iron, sucrose, and fat free pork, then Shrek poisoned Buzz Light year because Shrek was the only known suspect to bring those material. It was incorrect. The Crime Scene objects ended up being water, zinc, sucrose, and regular pork. Which is not what Shrek had( water, iron, sucrose, and fat free pork). After consulting the victims list, there is only one person who it could be, Sponge bob. There were some limitations in the above experiments, for example; the mass post-squeeze was rather limited because you had no way of equally squeezing the hot dogs. That could also be an example as a major flaw. Another example of a flaw are the density tests. The water displacement is so small in some cases, it's hard to get an accurate result. Your not alone though, I've read an article that can be found on this link- http://science.howstuffworks.com/csi5.htm - and it talks about how real life crime scene investigations work. It was basically the exact same concept for the procedures and experiments as the experiments above, just more complex. If you watch crime investigations on T.V. you may notice that they always seem to find "buts" and need more information or they have to modify and redo their experiments.
