Henry Brouwer
I am a retired Professor of Chemistry and Environmental Science (Redeemer University College). I have also taught Env. Chem. for 15 summers at the Au Sable Institute of Environmental Studies, located in Mancelona, MI. I have made a set of 4 DVDs, entitled Science Made Easy, which demonstrates and explains about 300 demos in the physical sciences using simple equipment for use by teachers, primarily in the elementary school. But many of the demos can be done at almost any grade level and with many different audiences.
