1st Quarter Extra Credit

1) Design and conduct a new science experiment. Make a poster.

2) Describe what went wrong in the fire/water bottle experiment. The first bottle had 25mL of alcohol, that we let evaporate and added a match. Boom! Then we added 75mL of alcohol to the same bottle, let it evaporate, and added a match. Small fire.

Why?!? Why did the second try end so weak?

Engrade me a 4-5 sentence answer with supporting evidence.
