Popcorn Project Investigation and Experimentation CA standard 6.7 Scientific progress is made by asking meaningful questions and conducting careful investigations.

Question/Problem (What do I want to find out?) Which popcorn kernels pop more volume, yellow or white?

Research 1) Moisture in popcorn should be about 13.5 to 14 percent 2) Most popcorn pops when the kernels reach 347degrees. 3) Kernels have a water moisture inside of them and the moisture turns to steam when it pops 4) Popcorn needs a hull to pop 5) Each kernel contains a tiny drop of water that when it is heated expands, causing the kernel to pop. 6) When popcorn pops, the seed turns inside out.

Hypothesis (What do you think?) I think that _______ kernels will pop more volume, because…

Materials (What do I need to conduct the experiment?) Popcorn kernels (50 white/50 yellow) Popcorn popper Data sheet/writing utensils Measuring cups bowls

Procedures (How will I find out?) 1) Count out kernels. You will need 50 kernels of yellow and 50 kernels of white. 2) Pop the popcorn. Each group will perform one trial each, popping the yellow & the white kernels. 3) Measure the volume of the popped popcorn. Record results after each trial. Report group results to instructor

Results (What actually happened?) Class data collection/Analysis

Conclusion What did we learn? Was my hypothesis correct?  Answer the following questions  What was the purpose of this experiment?  What were the results?  Was your hypothesis correct?  What do you think may have affected the outcome?  What would you do differently next time to achieve more accurate results?
