Investigation: How Do Insects Move?
Have you ever thought about how insects with 6 legs actually crawl? Human movement on two legs is pretty simple: left-right-left-right, but all insects have 6 legs attached to a thorax. In this activity, I ask students to observe an insect closely, usually a dubia roach.
