Thinking Like a Scientist:
Why Don’t Some Popcorn Kernels Pop?

Ask Questions

Observations often lead to questions. You may

wonder why you like popcorn or why certain kernels

don’t pop. “Why do I like popcorn?” is not a scientific

question. You cannot test this question. However,

“Why don’t all of the kernels pop?” is a scientific

question. You can test this question.
