In this game, students use their bodies to illustrate how temperature, density, and volume affect air pressure. Temperature affects how particles move. As air warms up, the particles start to vibrate and bump into each other, increasing the space around each particle. Because each particle uses more space for motion, the air expands and becomes less dense (lighter). […]
