    • 1.1: Invertebrates Diversity Protocol
      Vertebrates are animals that have a backbone. For example, you are a vertebrate. Invertebrates are animals that do not have a backbone. For example, an earthworm is an invertebrate. Today, you will observe four types of invertebrates: earthworms, mealworms, crickets, and crayfish. In the end, you will compare these invertebrates with some familiar vertebrates. This chart shows the classification of these animals. (Some information has been omitted to keep things simple.)
    • 1.2: Invertebrates Diversity Teacher's Preparation Notes
      This activity will introduce students to some of the variety of animal form and function, including varied methods of locomotion, relate form to function, including the advantages of bilateral symmetry and cephalization, and identify the distinction between similarities due to shared evolutionary history (animals in the same phylum) and similarities related to having a similar lifestyle (burrowing animals).
