A Catalyst and the Rate of Reaction

"Students watch a video and do a quick activity to see that a catalyst can increase the rate of the breakdown (decomposition) of hydrogen peroxide." Includes multimedia and all handouts. After using the demonstrations in class, have your students complete the activity under the "explore" section to explore both catalysts and a decomposition reaction. This activity is inexpensive and creates the "excitement" that students often look for. Uses the "5E" learning cycle.
