Students explain the mole concept and use this concept to prepare chemical solutions of particular molarities.

Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Learners quantify the relationship between temperature, energy and heat and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.

Young scholars explain how to make solutions with specific concentration. In this chemistry lesson, students differentiate acids and bases. They calculate molarity of solutions.

Students review balancing chemical equations. In this chemistry lesson, students calculate moles of an unknown substance based on stoichiometric relationships in the balanced equation. They cite applications of stoichiometry in the...

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

Students investigate the concept of a thermodynamic system. The difference between a state and phase is defined as part of the experimental explanations given in writing. Students conduct experiments to demonstrate laws of science like...

Students observe what occurs as baking soda is heated. They explain why a chemical rather than a physical change occurred during the procedure. Pupils identify the tpe of reaction (decomposition). Students conduct a glowing splint...

Young scholars conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain...

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

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...

Eleventh graders use titration methods to study properties of antacids. They look at the strength, effectiveness, PH, and effect of supplements taken at the same time. They make observations after the different mixtures are combined and...
