When was the last time your class saw a catalyst in action? Chemistry scholars observe an activated complex during an engaging experiment. Through both color change and evolution of a gas, individuals gain insight into the...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

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...

Get a surprised reaction from trying out the chemical reaction. Scholars conduct a chemical experiment by adding yeast to hydrogen peroxide and dish soap in a plastic bottle. They learn that yeast contains a catalase enzyme that releases...

Learning names and formulas can be a daunting task for young chemists, so support their study with interactive puzzles! First, users match each formula with its correct name. Then, individuals use them to complete three logic games.

Many families use hydrogen peroxide to clean wounds, but should they? The presenter explains the science behind antiseptics. His conclusion, based on the science, is that we should use water and maybe a little soap to clean any wound.

Hydrogen peroxide bubbles might look painful on a cut, but they are actually doing an important job. The video explores enzymes by allowing learners to see active sites on enzymes and how substrates, like a key fitting a lock, fit within...

Make a Halloween pumpkin foam at the mouth! Using hydrogen peroxide, toothpaste, and yeast, you can recreate this chemical reaction in your classroom. It can lead to a discussion of the way ingredients mix together to make a new...

An exothermic reaction is demonstrated by showing what happens when hydrogen peroxide reacts with manganese dioxide. It creates the effect used by film makers to have a genie coming out of a bottle in a burst of cloudy gas. Spangler is...

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 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...

In honor of the 4th of July, Steve Spangler shows how to make an explosive concoction in red, white, and blue. Using hydrogen peroxide, dishwashing liquid, and yeast, he creates a colorful chemical reaction. Consider this combination...

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

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