Why is it so difficult to make two solid compounds react? Investigate the concepts of particle collisions and rate of reaction using a quick demonstration. The colorful experiment features two plain, white solids combining to form a...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Examine the concept of stoichiometry using common household products. Scholars perform chemical reactions and measure the reactants and products. They compare their measurements to predictions made from the chemical equations.

Students examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth as it...

Students work for a company that produces acetylaslicylic acid, aspirin. They have been assigned the task of determining if different packaging materials and/or environmental storage procedures can increase the shelf-life of the product.

Students conduct an experiment to compare the total mass of products to the mass of reactants. In this conservation of mass lesson plan, students devise an experiment to show that matter is neither created or destroyed in a chemical...

Students investigate mass-mass relationships using potassium carbonate and hydrochloric acid. In this mass-mass relationship lesson plan, students measure a certain amount of potassium carbonate and determine how much hydrochloric acid...

High schoolers investigate mass-mass relationships in the lab. In this mass-mass relationship lesson plan, students mix sodium carbonate with hydrochloric acid to produce sodium chloride, water and carbon dioxide. High schoolers use the...

Fifth graders, in groups, complete two activities in which various substances are combined, resulting in a very different substances. They discuss reactants and products and chemical reactions.

Students measure the temperature change involved in the production of carbon dioxide by yeast. They also identify products and reactants in a chemical and balance the equation.

Sixth graders combine chemicals to create a chemical change. In this chemicals lesson plan, 6th graders will investigate characteristics of chemical change by combining chemicals. They will learn that color change is an indicator of...

Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Students recognize epoxy glue formation as two part polymerization (usually the curing agents act as co-monomers). They monitor the reaction by the changes in viscosity of the reacting mass, the temperature rise and fall, and the...

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Students investigate the effects of adding or removing a reactant or a product on chemical equilibrium. In this equilibrium lesson plan, students add or remove ions to solutions to determine the effects on equilibrium. They make...

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Students conduct labs to gain an overview of chemical reactions. They observe examples of synthesis, decomposition, single displacement and double displacement reactions. They identify certain products by the use of litmus and splint tests.

Eighth graders explore chemical reactions and their products. They define a chemical reaction and describe the characteristics of a chemical reaction. Students classify chemical reactions.

Seventh graders distinguish between physical and chemical changes in both natural and technological settings. They identify the reactants and products for a given chemical reaction. they then write simple chemical equations given the...

Students define and identify endothermic/exothermic reactions. Using a series of experiments, they construct and interpret potential energy diagrams for their reactions.
