Catalysis

Adsorption, not absorption, is when atoms stick to the surface of an object, like water sticking to a grain of sand. An informative lesson delves into adsorption, teaching physical and chemisorption and the factors that affect them....

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

Show your classes the science behind rates of reactions with a presentation that explains factors that affect the rate, activation energies, exothermic and endothermic processes, and the proportionality of the product and reactant rates. 

A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...

Jump-start your understanding of catalysis in chemical reactions. An educational video explains the basic concept of catalysis and its relation to energy. It also introduces platinum plates as a catalyst for the reaction between hydrogen...

Young scholars explore enzyme catalysis through a series of experiments. In this chemistry lesson plan, students determine the factors affecting catalysis. They explain the different uses of this process.

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

Students pretend to be enzyme that breaks toothpicks in timed intervals. They complete calculations to determine how many toothpicks are broken per second to determine the rate of reaction of the enzyme.

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...

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the challenge...
