Reinforcement Activities
Varying Rates of Decay in Decomposition Chambers
Have students experiment with different conditions to vary the rates of decay in different decomposition chambers. They can systematically change one variable between different chambers (keeping everything else the same) to see how that one variable affects the rate of decay.
