Reflection: Coherence Nature's Suction Cups? - Section 4: Webquest: Echinoderm Diversity


In this teaching reflection, I explain the importance of observing live animal behavior.  Many students have a very limited knowledge of the aquatic animals that we dissect.  If we only dissect those animals without having students observe how the animal acts, eats, breathe, and otherwise responds to stimuli, then we may feed future misconceptions.

Nature's Suction Cups?

Unit 11: Invertebrates
Lesson 8 of 12

Objective: By observing echinoderm behavior and comparing and contrasting echinoderm anatomy, students will evaluate how the water-vascular system and tube feet are adaptations that enable them to be successful.

Big Idea: Even though certain living organisms can have similar specialized organs, there can still be a great deal of diversity within the phylum.
