EPISODE DESCRIPTION

Physics is the study of nature. So, physics classes typically include demonstrations of how those laws of nature play out, often in surprising ways. But do students see what we intend them to see? In this episode, we find out what the research says about classroom demos, and how to help students get the most out of them.
