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..

This activity allows students to see many different types of scales in order to become proficient at measuring and determining how many digits to record in any measurement, whether it be volumes, masses, lengths, etc.

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.

Using the online simulation tool (Atomsmith Classroom Online) and the ADI framework students investigate the properties of gases, along with two gas laws. An ADI "whiteboard discussion" helps in getting students to really process what the results of experiments mean to us as chemists - and how this leads to expanding our understanding of matter. This activity lends itself to an online classroom.

The use of anthocyanins in red cabbage extracts as pH indicators has long been a popular classroom activity. Flowers, fruits and vegetables contain a diverse range of anthocyanins. This investigation explores further applications of plant-derived dyes including reversible reactions based on oxidation/reduction chemistry and other reactions to illustrate colour changes that are not solely dependent on pH change. By using household materials and plant dyes, this investigation may potentially be completed at home if necessary.

Many teachers have students draw models and diagrams to help them illustrate how matter behaves. Teachers can uncover and address possible misconceptions quickly using this strategy. The author describes how to create interactive particle diagram activities that are easy for students to use online. This strategy is applicable to almost any particle diagram and should be useful for teachers during virtual lessons.

In "Comparing household chemicals" students discover the effects of using different types of household chemicals and determine if they are really all so different. This formative assessment targets the question “What are the effects of using and producing different matter types?” This is important because students should understand the types of products they are using. If they are buying something that says it is a cleaner for the bathroom, why does it sometimes have the same compounds in it as a cleaner for the kitchen. If students can recognize this, then they can be better consumers and not have to buy two different products knowing that the chemicals are the same.
