1. Who poisoned Buzz Light-year? By: Julie Forero

2. Introduction Buzz Light-year and Woody were holding auditions for a T.V. show when something terrible happened. Buzz was found poisoned and the only thing left was a few evidence. There was a bitten hotdog, bended metal, 6 spots of white powder around the table, 175 mL of liquid, outline of Buzz, and 1 spot of yellow powder. The only thing is poor Buzz is in the hospital out cold and h can’t tell us who did it. We’ve hired the best detectives to help us solve this case and they are Mystery Incorporated.

3. Hypothesis The first thing the Mystery Gang did was develop a hypothesis. “We think Snow White poisoned Buzz Because of the materials she bought.” exclaimed Velma.

56. Conclusion We’ve finally solved this mystery. “We thought Snow White poisoned Buzz because of the materials she bought, but we were incorrect.” According to all the information Mystery Inc. collected Arial poisoned Buzz Light-year. “The data we collected shows that Arial did this crime. As you can see from the data we collected the suspect had to have brought water, iron, sucrose, and a pork hotdog. The only person who bought that was Arial.” From what you can see not every experiment is perfect. There a a few bumps on the road. While Mystery Inc. were trying to find the clues to help them solve this case there were a few flaws. For example, Scooby was trying to figure out how to work the conductivity meter because he always got the same answer. Then Velma told him what he needed to improve on, but what was interesting was how Mystery Inc.’s case related to a case a scientist read before. www.public.asu.edu/~langland/forensics.html
