1. Do You Cry?

2. Problem Does chilling an onion make it so that you don’t cry?

3. Hypothesis I think that it will, because the vapors in the onion are cooled down.

4. Materials 2 onions (one chilled, one unchilled) Stopwatch Paper/Pencil My Family

5. Procedure Gather all materials Buy two onions from the store Put one in the fridge, and leave one out Test the Unchilled onion Test the Chilled onion Record results

6. Variables Variable: Same onions Same refrigerator Dependant Variable: Whether or not they cry Independent Variable: Chilled or Unchilled

7. Results Unchilled: Dad- Chopped for 35 seconds and eyes were burning Mom- Chopped for 35 seconds and eyes were burning, at 52 seconds she was crying Kash- Chopped for 3 minutes and had no burning or crying Myself- Instantly burned, cried at 45 seconds

8. Results (continued) Chilled: Dad- Chopped for 42 seconds and eyes were burning, at 1 minute 17 seconds started crying Mom- Chopped for 53 seconds and eyes were burning, at 1 minute 17 seconds started crying Kash- Chopped for 2 minutes and had no irritation Myself- Chopped for 30 seconds and at 45 seconds started crying

9. Conclusion In conclusion my hypothesis was correct! Chilling the onion did help, by a bit. I think that it is because of the vapors and how they get cooled down. Then they don’t irratate the eyes as much.
