Collaborating chemistry pupils observe that temperatrue increases the movement of dye throughout water, stirring increases the dissolving rate of sugar cubes, and concentration of solutions increases the chemical reaction rates. These...

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

If your pupils think a catalyst is a list of their cats, then this might be the lesson plan for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...

Students complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

Students investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...

More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Students participate in a hands-on activity in which they observe the effect of temperature on the rate of chemical reactions. Using Alka Seltzer tablets in different temperatures of water, they record the amount of time it takes each...

High schoolers devise an experiment to test the rate of decomposition of hydrogen peroxide. In this rate of reactions lesson plan, students use the given information in the lab to write a procedure that will allow them to find the rate...

High schoolers recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical...

Middle schoolers research the type of chemical reaction that occurs when metal rusts. They conduct an experiment looking at the rate of corrosion in steel wool. This is lesson three in a three lesson unit on the transfer of energy.

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

Students create predictions on what they believe happen to reaction rates when temperature is raised. They use hot, cold, and room temperature water for this experiment and observe the differences. They graph their observations and...

Pupils explore linear functions in this lesson when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of slope...

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 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...

Students investigate the rate of a chemical reaction. In this rate of reactions lesson plan, students use an electronic balance to measure the change in mass of a chemical reaction between hydrochloric acid and calcium carbonate. They...

In this chemical reactions worksheet, students explain why certain reactions take place slowly or quickly. Students calculate the rate of consumption for given reactions. This worksheet has 14 problems to solve.

Learners examine different types of chemical reactions. They explore how alcohol molecules affect the reaction rates. They answer discussion questions to end the lesson plan.

Young scholars listen to a lecture on the collision theory. They discuss the reactant and product changes during a chemical reaction. Students are taught the factors affecting reaction rates. They complete a lab on entropy, heat and...

Surface area certainly surfaces as a variable for chemical reaction rates. Scholars perform an experiment to discover how the size of catalysts affect the rate of a chemical reaction. They record their results in tables and graphs to...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...
