Measuring Mass: Popcorn Lab

Here is a fun, simple, and yummy lab to help your students practice measuring mass.

Problem: Does the mass of a bag full of popcorn change after it is popped?

Hypothesis: Have students make a prediction. Example: “I think the bag of popcorn will have more mass after it is popped because the popcorn gets bigger when it pops.”

Complete the experiment.

Don’t forget to record the data and results!

Write a conclusion for the lab.

My bag of popcorn started at 101.5 grams, and went down to 98.6 grams after it was popped!

You could also tweak this experiment to observe the change in volume when popcorn is popped.
