Air Pressure: An Introduction

To introduce air pressure, students watched two videos: one of a 55 gallon barrel being crushed and a train car being crushed.  These are crushed just by the air! In groups, students are tasked with picking a video, drawing a picture of the video and explaining to the class what they think the physical mechanisms are.  We will note any key words and terms they use.  Check back for their posters and a list of words!
