This 43 slide PowerPoint overviews arachnids and then discusses separately spiders, scorpions, ticks, and mites. It begins by describing characteristics that all arachnids share. Slides 5 -28 discuss characteristics of spiders, how spiders can catch their prey, and labels the different parts of a spider. Slides 29 – 34 discuss scorpions. Slides 35 – 41 are about mites and ticks. Included are several youtube video suggestions that I like to use. You may also be interested in purchasing separately a note taking guide that students may fill out while viewing the PowerPoint.
