Reaction rates Lesson Plans

Students study reaction rates, what determines how fast a reaction happens and how the chemical changes occur.  In this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create a graph with their data.

Students investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction. Students use retest methods to determine how using various amounts of initial reactants changes the reaction rate.

Students study the collision theory and explain how the rate of a chemical reaction is influenced by the reaction conditions.  In this reactions lesson students divide into groups, discuss the factors that influence reaction rate and define a catalyst.

Tenth graders identify the parts and functions of the cell. In this series of science lessons, 10th graders investigate crystal formation in covalent compounds. They investigate the factors affecting reaction rates.

Learners identify the factors that affect reaction rates. In this chemistry lesson plan, students design a lab to test each factors identified. They create a Power Point presentation and share their findings in class.

Students identify the factors that affect reaction rates. In this chemistry lesson, students explain how concentration, catalyst and surface area speed up reactions. They create a presentation about the result of their experiment.

Students explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and analyze the data relating to the reaction they created during the experiment.

Students discuss the role of temperature in a person's reaction time and learn what a reaction rate is. They participate in an experiment in which reaction rates are recorded and discussed.

Students observe demonstrations to show factors that affect rates of chemical reactions. For this rates of chemical reactions lesson, students investigate how catalysts, reactant concentrations, temperature and surface area affect the rate of chemical reactions.

Students pretend to be an enzyme "thoothpickase" which breaks toothpicks in timed intervals. They complete calculations to determine how many toothpicks are broken per second to determine the rate of reaction of the enzyme.
