Bivalves

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.

Computer Lab Etiquette

You are in the computer lab to do work for this class. If you are not doing work, then we will have problems.

Do not pack up early. Work until the bell or until MsJ says.

SAVE OFTEN. And if you save to a key, also save it to your number. If you lose it, you will have to do it again.

If MsJ asks for your attention, stop what you are doing and listen to what she has to say.

You may watch videos about your organism through reliable websites.

You may listen to music through the computer if you have your own headphones. Rule1 MsJ cannot hear it. You get one warning. Rule2 Turn it on and listen – no million clicks and constant changing. Take both ear phones out when MsJ is talking.
