Investigating Gases & Airs, Class Kit

An Investigation of Air and Its make-Up (Grades 5-8) Learn about air, its nature and how air interacts with various objects in our environment. The first lab will allow students to establish that air is real, even if it can not be seen. Further experiments measure the oxygen content of air while students learn the use of scientific controls. The other ESS units “Balloons and Gases” (KT-1018) and “Kitchen Physics” (KT-1037) expand upon these concepts.
