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 investigate a combustion reaction. In this combustion lesson plan, students mix dry yeast with hydrogen peroxide in a test tube. They place a glowing splint in the test tube and observe the combustion reaction as the splint...

Students conduct an experiment to determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.

Students observe and record what occurs when yeast is added to hydrogen peroxide. They indicate why a chemical reaction (decompostion) must have occurred during the experiement. Pupils explain why yeast was used. Students comprehend the...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Young scholars determine the meanings of concentration, surface area, and catalysis through an experiment. In this lesson about chemical reactions, students participate in an experiment. Young scholars complete three different parts of...

Students explore gases. In this chemical energy lesson, students will observer chemical reactions and infer a conclusion about reaction producing gasses.

Middle schoolers investigate gases and their properties by completing 4 activities. In this gases lesson plan, students perform activities to show that gases take up space, they diffuse, and that odors and vibrations pass through gases....

Students are introduced to gases. In this science lesson plan, students demonstrate that gases are a state of matter, generate a number of gases, discover some properties of gases, compare some of the properties of different gases, and...

High schoolers engage in a lab project to study chemical reactions. They use guided questions to help facilitate the lab experience and come to the correct outcomes. The lesson does not contain a true understandable objective. The lesson...

Sixth graders explore chemical and physical changes. For this lesson about chemical changes, 6th graders observe various items and changes that occur at certain times. Students determine what change took place and observe the change....
