This 36 slide PowerPoint presents the worm family. First, characteristics of all worms are given with photographs of 12 different types of worms. The PowerPoint then speaks about the three most commonly studied worms: flatworms, roundworms, and segmented worms. There are descriptions of each group along with photographs. You may also be interested in purchasing separately the note taking guide students may fill out while viewing the PowerPoint. I find that this helps to keep them engaged throughout the lesson. I follow up this PowerPoint with an earthworm dissection.
