Class Experience

I have many years experience teaching nearly every grade level science class in elementary, middle, secondary in the public and private schools. I have taught middle school physical science science as well as science education classes in a teacher education department.

15 sheets of computer paper, scissors, a couple large paper clips, binder clip

40 minutes per week in class, and maybe some time outside of class.
There are no safety issues associated with the activities or demonstrations.
