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 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, 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.

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....

Students are introduced to stoichiometric relationships in chemical equations with a Trail Mix activity before performing a lab to reinforce stoichiometry. Students complete the unit with a lab about limiting reactants in chemical...

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...

All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...

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...

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.

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 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...

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...

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...

Students investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio of...

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.

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...

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 reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction...

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Students experiment to determine the effect of the frequency of collisions between atoms or ions of the reactants. They investigate the rate at which aluminum replaces hydrogen from a solution of hydrochloric acid.

Students work in groups to define chemistry vocabulary including the terms reactants, products, exothermic and endothermic. They then combine the group definitions to arrive at a consensus definition for the class. Students also listen...

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...
