Can you figure out how this experiment works?
Flinn Scientific has a great elearning video series. Many of the videos have master teachers demonstrating some great labs and techniques that they do in the classroom.
I am fascinated by the chemistry of pennies. I have tried several experiments found in the Journal of Chemical Education.
This is a series of experiments, PhET Interactive Simulation activities, and clicker questions to relate macroscopic and molecular representations of homogenenous solutions. Graphing skills are also used.
