What's the Difference?

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 -...

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...

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. 

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...

Out of all animals, elephants alone lack the ability to jump. Scholars learn all about animals using a presentation full of fun examples. It describes different types of animals, the biological similarities and differences between...

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

Learners 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 create an animal by using physical characteristics to classify that animal in the Linnaean Classification System. This lesson plan is part of a multi-segmented 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.
