Vertebrates

Geologists are gneiss, tuff, and a little bit wacke. The fifth chapter of seven includes ten activities at four different levels. The hands-on activities cover fossils including how they are formed, vertebrates, invertebrates,...

Eighth graders classify vertebrate animals according to their characteristics. For this life science lesson, 8th graders distinguish among the seven classes of vertebrates. They examine similar characteristics among those that belong to...

The 13th part in a series of 20 introduces pupils to vertebrates and how animals are further classified. They use a biological key to classify different types of vertebrates and then sort 30 images of organisms into their correct...

What features do scientists use to classify animals into groups? Class groups examine a series of paired images of vertebrates (a bass and a trout, a toad and a newt, a crocodile and a tortoise, an owl and a robin, a tiger and a bear)...

Spine or no spine? Vertebrate or invertebrate? Learners sort and classify a list of animals as vertebrates or invertebrates into a graphic organizer.

Jump into an exploration of marine ecosystems with the first lesson in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

What a terrific lesson! Learners discuss the animal kingdom, and classify them as vertebrates and invertebrates. They also identify them as fish, amphibians, reptiles, birds, and mammals. There is even a taxonomic breakdown of popular...

Comparative anatomy prevails in the lesson exploring diversity among invertebrates. Biologists examine physical characteristics of an earthworm from phylum annelida and a meal worm from phylum insecta. They also inspect a cricket and a...

All mammals have warm blood, are vertebrates, breathe with their lungs, have hair or fur on their bodies, and produce milk for their young. But not all mammals give birth to their young in the same manner. Watch a video that explains how...

Not all animals respond to pain the same way. Thanks to the structure of the nervous systems of different living organisms, vertebrates and invertebrates experience nociception—the sensory nervous system's response to pain.
