observations

The White Powder Activity

 I always feel a need to start the year off with an activity that ties in observations and conclusions but I also know that most students have had that in science classes since the early grades. Is there a way to revisit an old topic with a new or more challenging bent?

 

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.
