Today students learned about bivalves. Bivalves are molluscs that have two shells and two siphons. Bivalves include some of the more well know shellfish liek scallops, clams, oysters, and scallops as well as a few like jingles, ark shells, and cockles.
Students built a model of a bivalve and had to put in the mantle (the soft squishy part), the gills, siphons if it had them, adductor muscles (used to keep the shell shut), and maybe one other thing unique to the type.
Mussels make byssal threads for attaching and scallops have eyespots to see predators. Sam and LaQuin are making scallops.
On Monday students will compare and contrast the different models to get a true understanding of the similarities and adaptations of bivalves.
