Science Fair Project :Science Fair Project Popping Popcorn
Investigative Statement :Investigative Statement Are all brands of popcorn created equal?
Main Question:
Do different brands of popcorn leave different amounts of unpopped kernels?
Hypothesis :Hypothesis The popcorn brands will leave around the same amount of unpopped kernels.
