concentrations on the rate of chemical reactions can be applied to figuring out the correct dosage of medications and running the risk of an overdose. Allow for up to 5 minutes to have students read the background and answer questions, then 5 more minutes for the lab and analysis. You may use a 5 minute timer to keep students on track, and so that all students move at the same time. Learning Target By the end of class students will be able to observe and predict the changes in reaction rates with changes in surface area temperature molecular motion concentrations, applications of catalysts and enzymes. Time Estimated Time Actual Time (please make note below) Station 1: Surface Area 10-15 minutes – Station 2: Temperature 10-15 minutes – Station 3: Stirring & Mixing - 10-15 minutes Station 4: Catalysts - 10-15 minutes Station 5: Enzymes - 10-15 minutes Station 6: Concentration - 10-15 minutes * allow 5 minutes to read and answer questions, then 5 minutes to do the lab and respond. You can easily cut out stations if you are limited on time, or do the lab over more than one class period.
