Wendy Pavlecik, from the Science Center, brought in some animals to help students understand vertebrates (animals with backbones), and invertebrates (no backbone, but have an exoskeleton). Our visitors are gerbils, Mongolian Hissing Cockroaches, and a crayfish. What types of animals are these? Vertebrates? Invertebrates? Ask your child, and in the meantime here are some photos to enjoy.
