Demonstrate Your Chemistry
Learners research and evaluate chemical reaction demonstrations that are found on the web. they work in small groups to choose a demonstration that fits a particular category of reaction and then perform the demonstration for the class.
Curated OER
H2O2 Decomposition Lab II
Students conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.

REDOX Lab
Students produce copper metal by electrolysis. In this REDOX lesson plan, students use a copper (II) chloride solution and a 9 volt battery to produce copper metal through an electrolysis reaction. Students make observations and take...
Curated OER
Uranium On a Diet
Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.
Curated OER
Down the Drain
Pupils examine the following concepts: If water supplies contain materials which rot or decompose, oxygen is used. Decay and decomposition require vast supplies of oxygen. The use of oxygen for decay of wastes may be a life or death...
Curated OER
Activity #13 Changing The Look of Sugar
Learners observe what happens when sugar is dissolved in water and when it is heated. They weigh the products after each of the two experiments on a balance scale. Pupils distinguish between physical and chemical changes. Students are...
Curated OER
Lab: Percent of Composition of KClO3
Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...
Curated OER
Lead and Mercury Ion Catalase Inhibition
Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.
Curated OER
Solid Waste and Recycling
Students demonstrate effects of waste on environment and ways of reducing it, observe how much packaging goes into bag lunches each day, and survey their families to assess awareness levels and household recycling practices. Lessons all...

Water Purification
Young scholars develop an understanding and appreciation of water purification techniques and their implications for health maintenance.
Curated OER
Catalase and Catalysis
Students explore enzyme catalysis through a series of experiments. In this chemistry lesson, students determine the factors affecting catalysis. They explain the different uses of this process.
Curated OER
Mulch
High schoolers conduct a series of experiments on mulching. In this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.
Curated OER
Chemical Equilibrium
Learners explore Le Chatelier's Principle. In this instructional activity about chemical equilibrium, students do an experiment with several different activities . Learners observe as they do the experiments and understand the outcome....
