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...

Learners 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...

Students 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 of...

How far have California's Channel islands moved? What was the rate of this movement? Class members first examine data that shows the age of the Hawaiian island chain and the average speed of the Pacific Plate. They then watch West...

Pump up your class while studying the cardiovascular system with this pair of activities. In one, learners record heart rates during different actions. In the second, they read kid-friendly heart health articles online and then write a...

With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...

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...

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...

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Students explore critical thinking by conducting a reaction time experiment. In this human brain lesson, students utilize a timed Internet worksheet activity to research how fast their brain works when answering questions. Students share...

A hands-on lesson plan using the TI-CBR Motion Detector to provide information to graph and analyze. The class uses this information to calculate the slope of motion graphs and differentiate scalar and vector quantities. There is a...

Students explore how muscles work. In this health lesson, students identify how the blood supplies muscles with oxygen. Students participate in an online activity to reinforce the concepts.

Though UV radiation can damage skin, it isn't all bad. The third installment in a six-part series allows the class to study the structure and function of skin. They learn about the different types of skin cancer and the SPF rating...

Which activity gets your heart pumping more: using the computer, climbing the stairs, jumping rope, running, or walking? Youngsters take a heart rate reading after 30 seconds, one minute, and three minutes of each activity. The handout...

Is your stoichiometry lesson plan just not adding up? Incorporate an exciting interactive to balance things out! Chemistry scholars manipulate the number of molecules added to the reaction vessel, then observe as bonds form and break as...

More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...

Learning to craft quality questions is a skill that can be taught. Class members use the Question Formulation Technique to learn how to create and refine both closed-ended and open-ended questions. They then view West of the West's...

Learners study urban runoff. They identify the urban runoff in a simulated area and determine peak flows using charted data. Finally, they discuss possible causes of the differences in flow rates.

Students are introduced to the concepts of a watershed, stream flow and water quality. This five-day plan is an excellent way to introduce students to the concepts involved. They create their own watershed using a paper bag, water and...

The goal of this fine geology lesson is to have learners create a map that shows how the rock layers are arranged far underground where they can't be seen. The ambitious lesson plan requires high schoolers to learn the law of...

Students listen to their heart beats. In this biology lesson plan, students explore pulse rates and factors that cause them to change. Students also construct both a graph to show variation in pulse rates and a simple stethoscope.

Here is an engaging and hands-on lesson plan that allows high school chemists to demonstrate the effects of a catalyst on various chemicals. They garner knowledge of how reactants and products differ from one another, while...
