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

Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...

Using an inquiry approach to studying biochemical reactions, cooperative teams of pupils investigate hypotheses about living materials that contain enzymes which break down in hydrogen peroxide. They perform experiments, practice...

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson plan of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

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

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.

High schoolers investigate the effects of a catalyst on an oxidation reaction. In this catalyst lesson plan, students use a catalyst, cobalt chloride for the oxidation reaction of potassium sodium tartrate with hydrogen peroxide. High...

Use demonstrations to enlighten learners on oxygen's role in combustion. Use potatoes and hydrogen peroxide to increase oxygen concentration in a jar, then stick a glowing splint and a burning wad of steel wool into the newly formed...

Students explore the role of enzymes in chemical reactions. In this enzymes lesson plan, students use hydrogen peroxide and manganese dioxide to observe a chemical reaction. Students observe the rates of reactions of chalk, hamburger,...

High schoolers observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other...

Students investigate the rate determining step in a chemical reaction and how catalysts effect reactions. In this rate determining step and catalyst lesson, students work in groups to perform 5 tasks. They rotate each task and time how...

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...

Sixth graders discover how disease spreads. In this disease control lesson, 6th graders brainstorm a list of diseases and simulate how a disease spreads by using cups of hydrogen peroxide and water. Students create the "Fizzies Virus"...

Here are photos and general instructions for demonstrating two oxidation reactions with your physical science beginners. They use salt and hydrogen peroxide to cause iron filings to rust, and they combine hydrogen peroxide with a piece...

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

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...

Students explore biochemical reactions mediated by enzymes in an inquiry approach. They are given two questions about the types of living materials that contain the enzymes that break down hydrogen peroxide, and under what conditions the...

Students investigate alternative catalysts for the degradation of hydrogen peroxide.  In this fermentation lesson students complete an activity that breaks down cellulose into sugar. 

Fifth graders perform experiments to determine the identity of an unknown gas sample. In this chemistry lesson, 5th graders fill balloons with air, oxygen, hydrogen, and carbon dioxide. They use mass and reactivity to identify the gases.

Students recognize the presence of organic matter in soils from their immediate area and recognize which soil sample contains the highest concentration of organic matter.
