Lesson Plan - Get It!


I may not have a backbone, but I’m not scared.

The animal kingdom is divided into two groups: vertebrates and invertebrates.

Invertebrates are animals without a backbone. Scientists classify or group invertebrates into different categories:

  • worms
  • jellyfish
  • mollusks
  • arthropods
  • corals
  • echinoderms
  • sponges

In this lesson, you will learn the characteristics and classification of invertebrates using video, various online resources, graphic organizers, and an innovative project.

Let’s get started!

Watch Invertebrate Animals from Happy Learning TV, and learn how scientists classify invertebrates.

Pause the video to take notes using the Classifying Invertebrates – Notes found in the Downloadable Resources in the right-hand sidebar. Take notes on the characteristics of invertebrates as well as add examples of the types of animals found in each category.
