Laboratory 4: The Molluscs

A green van stops. A temperature is rising. Six guys, steel in eyes and hands full of cardboard boxes. What do they want? They come for your children.

Today is Monday and it means new laboratory full of Molluscsc and its main three classes: Cephalopoda, Gastropoda, Bivalvia. We open today´s lesson with competition between three teams, we summarize the knowledge of the previous three families: Porifera, Cnidari, Echinodermi.

Immediately after it is time for the first game. The four teams and fourty octopuses around square. Find the octopus which is a master at hiding. Do you know that the octopus passes through each hole that is at least as great as of her eye or that no octopus can live in fresh water?

The second game is focused on Bivalvia because most of them bury themselves in sediment. So do not hesitate child and explore what is inside sand. The last game is hunting. Bivalvia have laterally compressed bodies enclosed by a shell consisting of two hinged parts and snails from Gastropoda family have just one external shell big enough that the soft parts can withdraw completely into it. Of course that Gostropoda family is not represented by snails but also by slugs and other different organisms. And what the hunting game is about? Every child chooses who is and takes one cardboard box or two of them. These children try to move. Do not let octopuses eat you, child! Be careful and hide yourself everytime when a shadow flies above you.

At the end of the evening you could listen to the tales about Echinodermata written by children.
