This is a 35 slide PowerPoint over Echinoderms. The first 8 slides discuss similar traits of all echinoderms. The rest of the PowerPoint looks at 7 common echinoderms: starfish, brittle stars, sea urchins, sand dollars, sea cucumbers, sea lilies, and feather stars. There are facts and photos of each kind. The formatting is with fill-in-the-blanks. I like to have students try to guess what word may fit in the blank before revealing with a click.
