What is Science?

Today I asked students what they felt science was.  We eventually figured out that it was asking a question and then trying to figure out the answer to this question.  The question I asked them today was the following:  What will happen if you put an antacid tablet inside a film canister, filled halfway with water, and seal it shut completely?    The answer is shown in the video below.  Don't be afraid to ask you child why this happened.
