The world we live in is covered with air, called the atmosphere. To explain to students about the different properties of air, a virtual activity was conducted in Grade 4. This activity focussed on the physical properties of air. In this activity, students conducted investigations that helped them to develop and refine their ideas about air. This activity addressed some of the physical properties of air on the substance level to help students build a future understanding of how air particles behave on a molecular level. By performing several simple experiments, students developed an understanding of the properties of air, such as it has mass, takes up space, exerts pressure, or it expands on heating.
