As if scientists don’t do enough awesomeness in their day-to-day jobs, the American Chemical Society took the time to write an entire, free, multimedia Middle School Chemistry curriculum. Over forty lessons divided into six chapters, complete with lesson plans, hand outs, related reading and cool videos – all to download for free. This is an in-depth, inquiry-based curriculum with lots of hands-on experiments. For grades 6-8 and completely free.
