I have long felt that teaching directly to the test is not the best way to approach education. Therefore I often include topics in my AP Chemistry classes that are not directly tested on the exam. More complex topics often help my students with building their grasp of fundamental ideas and leads to a better ability to understand simple and complex theories.

In this activity, students learn about solubility and concentration. They watch videos that explain the dissolving process, how to calculate the molarity, supersaturation and how to make rock candy. They also use a PhET simulation to explore factors that affect the concentration of a solution.

In this activity, students learn about the mole. In section 1, students learn what a mole looks like for different substances. In section 2, students learn how the number of protons and neutrons in the nucleus determines the molar mass of an element by comparing individual isotopes in a PhET simulation..

In this lab students are given a film canister, a quantity of Alka Seltzer of their own choosing and any materials available in the room to investigate factors that affect the rate of reaction. They work with their groups to create CER boards and then the class engages in a Glow and Grow session. Tips for using this activity in a virtual setting are offered as well.
