High schoolers conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

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

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