Day Fifteen

As part of our preparation for our tide pool adventure coming up on Thursday, we examined different mollusk shells today. Some of the things we learned are that there are 2 different types of mollusks, bivalves (2 shells) and univalves (1 shell). Using detailed descriptions of each type of shell, students were able to match each shell with its name. We also labeled sample bivalves and univalves. Some of the new words we learned are: siphon tubes (used to get food and get rid of waste), operculum (how univalves hide themselves in their shell, like a door), hinge (where the 2 shells in a bivalve are connected together to open and shut), and foot (how the mollusk moves).
