Who Poisoned Buzz Lightyear ?

1. Who Poisoned Buzz Lightyear? By: Kristijonas Bileisis

2. Introduction • The purpose of this experiment was to better understand Chemistry and how to work in a lab. I already know that certain substances react with other substances. I also know how to find the density of an object and that if a substance floats in water; its density has to be above 1.00. I also know what malleability, conductivity, density, luster, reactivity, flammability, heterogeneous, homogeneous, element, compound, pure substance, mixture, color, odor, solubility, mass, and what melting is.

3. Hypothesis • If somebody poisoned Buzz Lightyear, then Ariel did it, because the powder at the crime scene was white. The liquid at the crime scene was clear. The hot dog was an actual hot dog. The wrap was a metallic color. All of the items Ariel brought match the description of these observations.

4. Materials • hand lenses, spoons, triple beam balance, stirring rods, matches, paper cups, hot plates, iodine, well plate, beakers, eye droppers, sodium bicarbonate, conductivity meter, balance, graduated cylinder, HCI (hydrochloric acid), goggles, forceps, pork hot dog, light pork hot dog, fat free hot dog, sucrose, baking soda, sodium polyacrylate, sodium chloride, ascorbic acid, plastic, aluminum, zinc, copper, iron, sulfur, pure water, rubbing alcohol, salt water, vinegar, grape drink, paper towels, aluminum foil and lemonade with pulp

5. Procedures

6. Safety • Make sure while doing all of the procedures, you follow all safety rules such as wearing safety goggles, pulling your hair behind your head and etc.

7. Finding the Density of the Liquids • First, find a graduated cylinder. • Then, get all the liquids. • Pour in the Pure Water first into the graduated cylinder. • Next, pour in a liquid and record if the liquid stays above or below the Pure Water. • If the liquid stays above the Pure Water, it is less dense than Pure Water. If the liquid stays below Pure Water it is denser than Pure Water. • Record if it’s denser or less dense than Pure Water. • Repeat steps 3-7 for all the liquids you have.

8. Finding the Color of the Liquids • First, get all the liquids. • Look at a liquid and determine what color it is. • Record what color it is. • Repeat steps 2-3 for all the liquids you have.

9. Finding if the Liquids are Conductible • First, get all the liquids. • Then, get a conductivity meter. • Second, make sure the conductivity meter is on by moving the switch on to the “on” position. • Third, stick the metal rods on the end of the meter into a liquid. • Record how conductible the liquid is. • If the light bulb on the meter is very bright, its conductibility is very high. If the light bulb on the meter is bright, its conductibility is high. If the light bulb on the meter is dim, its conductibility is medium. If the light bulb on the meter is not lighting up, it is not conductible. • When finished with one liquid, wipe the liquid off the metal rods on the end of the meter with a paper towel. • Repeat steps 3-7 for all the liquids that are used.

10. Finding the odor of the liquids • First, get all the liquids. • Second, don’t stick your nose into the liquid but waft the smell to your nose. • Finally, record what the odor smells like. • Repeat steps 2-3 for all the liquids.

11. Finding if the liquids are Flammable • First, get all your liquids. • Second, carefully light a match and safely put it in the liquid. Make sure to move your hand away quickly. • Quickly put out the fire if there is one. • Record if the liquids are flammable. • Repeat steps 2-4 for all the liquids used.

12. Finding if the liquids are Reactive • First, get all your liquids. • Second, get some baking soda and one spoon. • Carefully, put a small amount of baking soda onto the spoon. • Fourth, put the small amount of baking soda into the liquid you are testing. • Record what happens to the liquid when you put the baking soda in it. • Repeat steps 3-5 for all the liquids used.

13. Finding if the wraps are Malleable • First, get all the wraps. • Second, get a pair of forceps. • With the pair of forceps, try to bend the wrap. • Record if the wraps bend. • Repeat steps 3-4 with all the wraps you have. • If the wrap bends, it is malleable. If it doesn’t bend or it shatters into pieces, it isn’t malleable.

14. Finding if the wraps are Conductive • First, get all the wraps. • Second, you get a conductivity meter. • Make sure the conductivity meter is on by moving the switch onto the “on” position. • Third, you place the metal rods on the end of the conductivity meter onto the wrap. • Record how conductible the wraps are. • If the light bulb on the meter is very bright, its conductibility is very high. If the light bulb on the meter is bright, its conductibility is high. If the light bulb on the meter is dim, its conductibility is medium. If the light bulb on the meter is not lighting up, it is not conductible. • Repeat steps 3-6 for all the wraps you have.

15. Finding the wraps Density • First, you get all the wraps. • Second, you retrieve a triple beam balance and a graduated cylinder. • Third, place the wrap onto the triple beam balance. • Move the mass blocks to the right spot so the scale is even with the white line on the end of it. • Record the wrap’s mass. • Fourth, fill up the graduated cylinder to 50 milliliters. • Fifth, using the same wrap used earlier, place the wrap in the graduated cylinder. • Record how many milliliters the water inside rises (how many milliliters it rises is the volume of the object). • Sixth, divide the mass of the wrap by the wrap’s volume and the answer you receive is the density of an object. • If the density of the wrap is above 1.00, then it should sink below the water (use that to make sure you did the math right). • Record the density of the object. • Repeat steps 2-11 for all the wraps you have.

16. Finding the Luster of the wrap • First, get all the wraps. • Second, look at the wrap and decide whether it is shiny or dull. • Record whether it is shiny or dull. • The shininess or dullness of the wrap is the luster of the wrap. • Repeat steps 2-3 for all the wraps you have.

17. Finding if the wraps React • First, get all the wraps. • Second, get some hydrochloric acid. • Third, use the eye dropper to obtain a tiny amount of hydrochloric acid. • Squeeze the eye dropper to make the hydrochloric acid to come out on top of the wrap. • Record what happens when you put the hydrochloric acid on top of the wrap. • Repeat steps 3-5 for all the wraps in the experiment.

18. Finding if the powders are Soluble • First, get all the powders. • Second, get some water, a stirring rod, and a spoon. • Scoop up a small of amount of powder with the spoon. • Put the powder that is on the spoon in the water. • Stir the water with the stirring rod. • Look and see if the powder if dissolving. • If the powder is dissolving, then it’s soluble. • Record whether it’s soluble or not. • Repeat steps 3-8 for all the powders in the experiment.

39. Results • In the end, my hypothesis was incorrect because the data seemed to show that SpongeBob was the person who poisoned Buzz Lightyear, not Ariel. The facts also state that SpongeBob did it. For example, the color of the hot dog was tan, so it had to be Pork. The powder had to be sucrose, because it was the only one that stayed in a liquid and had bubbles on the top when it melted. Also, the liquid had to be pure water, because the density of the pure water was 1g/ml and so was the crime scene liquid. Although the experiment did not tell which wrap she used, it had to be between zinc and aluminum and no other person had brought pure water, zinc or aluminum, sucrose and a pork hot dog.

40. Results • Although the experiment went well, there were some limitations. It was very difficult to see each individual liquid when put into the graduated cylinder. It would have been better if there was food coloring to use. Although we had most of the data, we still could have finished everything if we had managed our time wisely. Also, we could have squeezed out more liquid on the first two hot dogs. An experiment that could have come from this one was, “ What would happen if I mixed together some of the powders used with some of the liquids? How would they react?” The data I achieved shows how you can test chemical changes in a substance to determine what it is. In an article that I read, a police man tested a chemical change of a substance to see if it was cocaine. He used chemical changes to determine if the bad guy actually had cocaine and solved a crime.
