It's Windy Up There - Assessment

WHY?

The air in the warm end of the aquarium will expand and rise. Next, the cool air at the other end of the aquarium will contract and sink. The cool air will flow in to replace the sinking cool air. A circulating wind will develop in the aquarium. The smoke enables you to see the movement of the air. This is a convection current.

ASSESSMENT: Can the student communicate what they observed?
