In my 8th grade class, I teach a unit over entomology. This is the first lesson in that unit, which covers insect classification. There is a PowerPoint and a set of guided notes. This is a fairly simple lesson, so I utilize it in my lower level classes. It includes a website resource to classify insects, as well as a closer e-moment.
Classify insects according to classification system
Identify various insect orders
PowerPoint: 14 Slides
