Today very few animals exist with both an endoskeleton and exoskeleton. Yet, in the Devonian period, a large number of fish species lived with both. Scientists debate if they were for protection or mineral storage, because none of them...

What is the differences between exo and endoskeletons? Viewers have an opportunity to see the structure inside our bones and explore bone remodeling with a video about cartilage and bone formation in the human body. 

Help young biologists find their place in the animal kingdom with a life science presentation on the phylum chordata. Over the course of 54 slides, your class will dive deeper and deeper into the hierarchy of biological classification,...

What better way to study the structures of organisms than by creating a new being? After considering different types of skeletal supports (exoskeleton and endoskeleton), budding biogeneticists work together to create their own animals -...

Don't be chicken to try a lesson plan that compares the anatomy of birds to humans. Read the background information so you don't have to wing it when it comes to the anatomy of a chicken. Prepare cooked chicken bones by soaking them in a...

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...

Students analyze the similarities in different species. This lesson is part of a multi-segmented unit on the diversity of life. In this segment, students classify shoes to mimic the scientific categories of the classification system.

Guide your young scientists in reviewing basic animal processes including digestion and reproduction. Students review the stages of metamorphosis and the different types of body symmetry. This worksheet has 8 matching, 6 true or false, 4...

In this animal worksheet, high schoolers review various characteristics that are associated with animals including body plan and skeletal structure. This worksheet has 11 fill in the blank questions.

In this body plans and adaptations worksheet, students will review the different types of symmetry found in organisms. Kids will identify body parts as found on either the ventral or dorsal part of an animal. Then students will look at...

In this biology worksheet, students identify and locate various vocabulary terms relating to the classification of living things. There are 28 biology terms located in the word search.

Students are introduced to the unit on the importance of diversity of life and the role that interdependence plays in our worlds. this is part of a multi-lesson unit on the diversity of life.

Students are introduced to the variety of organisms in our world. this lesson is a part of a multi-segmented unit on specie diversity. this segment explores distribution of life on land and sea.

Students are introduced to the basic characteristics of the animal kingdom. this lesson is part of a multi-segmented unit on the diversity of life. In this segment, students explore the the members of a few phyla of the animal kingdom.

Students study physical characteristics of separate phyla and place them into similar groups. This lesson is part of a multi-segmented unit on the diversity of life. students develop a classification system by grouping animals into...

Students create an animal by using physical characteristics to classify that animal in the Linnaean Classification System. This lesson is part of a multi-segmented unit on the diversity of life.

Learners change one animal group into another animal group by changing only a few body characteristics. This lesson is part of a multi-segmented unit on the diversity of life. In this session, students the basis of classification.

Students investigate the importance of dependency and diversity in a rain forest ecosystem. This lesson is part of a multi-segmented unit on the diversity of life.
