SCIENCE WORD OF THE WEEK!
Welcome to class this week! We’re going to learn about the covering that invertebrates have. Do you remember what an invertebrate is? It’s animals with no skeleton!
An exoskeleton is the hard outer covering or external skeleton of an animal. Animals such as arthropods, insects and crustaceans have exoskeletons. Exoskeletons help protect the soft bodies of these animals. Shells are considered exoskeletons.
