The Types of Chemical Reactions Lab is a favorite for many teachers and students. Chemistry comes to life as students record observations. This virtual version by no means replaces the students physically conducting the reactions themselves but during these times this activity can be used to supplement the teaching of chemical reactions.

Writing formulas is one of those concepts in chemistry that requires much practice and repetition for students to gain confidence. This remote learning activity is a fun way for students to practice name and formula writing that will not be as boring as a worksheet full of practice questions.

Michael Morgan shares a lesson that he has used for many years that not only requires students to explain a topic that they have not been directly taught but also to develop explanations based on previous knowledge. He has used this lesson as a multiday “in-class” assignment and also as an “at-home” independent study. It works well in both scenarios with only minor revision. The lesson is based on Alfred Werner’s work on deducing the structures of coordination compounds.

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..
