Laboratory Instruction

Seeing Is Not Believing

“It sort of started to look kind of like a very pale blue.” A friend who teaches at the middle school level told me about a science experiment he’d done with his students. The procedure suggested to students that a particular solution would turn blue, but also asked them to write down what they saw happen. The thing was, it wasn’t actually designed to turn blue.

Putting It All Together: Lab Reports and Legos

In this Activity, students study a structure made from Lego blocks and then attempt to build the structure from memory. During a second examination of the structure, students write building instructions. The instructions are then given to another student who attempts to recreate the structure without looking at the original.
