Sea Star Dissection

As part of the 7th grade biology unit on animals, the class looked at different phylum found within a particular kingdom. The students talked with Ms. O about the different characteristics and important adaptations each animal has for survival.

As part of the lesson, students take part in multiple dissections in order to learn and compare the anatomies of common organisms. So far in their study of invertebrates, the class has dissected a squid (part of the mollusk phylum), a worm (the annelid phylum) and, this week, a sea start (a member of the echinoderm phylum).

Each organism has a different circulatory system, number of hearts, different sequence of body parts, and some have no brain at all! These dissections are a hands-on way students have been able to see the diversity of all life!
