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...

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...

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...

Pupils work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together and...

Young scholars 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.

Learners discover stoichiometric relationships in chemical equations. They review mole to mole conversions. They understand mass/particle conversions. They perform a lab to reinforce stoichiometry.

Young scholars examine stoichiometry. In this chemical reaction and mole lesson, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

Students examine gas production in "soil" samples through hands on activities and class discussions, to determine if the soil samples have contain living or non-living systems.

Students explore chemiluminescence through various experiments. In this chemistry activity, students explain the chemical reaction that drives the process. They give real life applications of chemiluminescence.
