Timing is everything in this engaging demonstration of the classic iodine clock reaction! Students observe how temperature, concentration, and the addition of a catalyst affect the rate at which a colorless solution changes to a deep blue color. They then model the reaction on a particulate level and calculate the rate of each reaction. This demonstration requires approximately 15 min of prep time and 30 min of classroom time, and materials are sufficient for 5 demonstrations.
