Expanding and Contracting Gases: Weekly Science Activity

Explore how gases contract and expland  / Hand-on STEM experiment

In this week's spotlight: a chemistry family science experiment that guides students and families in an exploration of how gases behave, especially when they are cooled or heated. Many gases are invisible, but they are everywhere around us. By trapping gas in a balloon, you can investigate how the kinetic energy of a gas changes in response to temperature and how the change in the motion of the gas molecules makes the balloon shrink or expand. With some hands-on measurements, a bit of air spent filling up some balloons, and some chill time for a few of the filled balloons, students can "see" what happens!
