Conserving Chemical Resources

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

In this moles learning exercise, students are given 9 problems where they find the number of grams, molecules, moles, or ions given one of these measurements and the chemical compound. Students calculate the number of atoms in a gallon...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...

Give your class a wealth of knowledge in mole money! Young chemists learn the fundamental concept of mole ratios through a video from JFR Science. The narrator covers conversion factors, creating mole ratios from balanced chemical...

Sal introduces chemistry students to the concept of "moles." He points out that a mole is a unit of measurement that helps a student to convert between grams and atomic mass units of any substance. Sal uses the element Aluminum to...

In this moles worksheet, students define a mole and convert grams to moles or moles to molecules. Students convert specific mass of compounds to moles. This worksheet has 1 true or false, 6 short answer, 3 fill in the blank, and 15...

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

One mole of a substance is equal to the molecular mass of the same substance. A video explains how to solve for the ratio of atoms to particles in a compound. It walks through a couple of example problems using moles to ensure viewers...

High schoolers 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...
