Students experiment to observe air and its mass.  For this air lesson, students use the scientific method to complete experiments that demonstrate the properties of air. Students view a video as follow-up.

Young scholars read a book and have a class discussion about the air around them. In this air lesson plan, students learn about properties of air, and discuss other gases they have observed.

Fourth graders conduct an experiment to get them thinking about the invisibility of air, and to prove that air has weight.
