Amaze your students with this cloud demonstration!

Ever wonder why meteorologists make such a big deal out of pressure. Help your students understand by showing them this cloud demonstration. Also, be sure to check out the other videos (see links below).

Here are the basics
Anything in nature that makes air rise will help clouds form. Fronts, mountains, convection, and storms all move air upward. As air rises it cools by expansion, and if it cools below its dew point clouds will form. Clouds are made of tiny droplets (or ice crystals) that form as vapor condenses on particles (pollution, dust, smoke, etc.).
