This 56 slide PowerPoint teaches the different types of clouds. It begins by describing what causes clouds to form. Then it defines prefixes and suffixes used in cloud types: Cirro, alto, nimbo, nimbus, cumulo, and strato. As each cloud type is described there are photographs to illustrate. Students will then make guesses when a table of review reveals one box at a time with a click. At the end, more photographs are given and students guess the cloud type. Also available for purchase is a note-taking guide that students can fill out while viewing the PowerPoint.
