This is the beginning of my Kinetic Molecular Theory unit. I start by providing the students with their study guide and copies of the powerpoint slides for the unit. At the title slide, I ask students if they know what kinetic means. We discuss that it means movement and therefore this theory is about the movement of molecules. I then attempt to engage their interest by showing a short video that starts with dirigibles, demonstrates hydrogen as lighter than air but flammable, carbon dioxide as heavier then air and nonflammable and then helium as lighter than air and nonflammable. For the explore portion, we discuss the five assumptions that describe an ideal gas. For assumption one that gases consist of large numbers of tiny particles relative to their size, I give every students a ball pit ball. I tell the students that each ball is a particle of gas; then I tell them to hold their particles in the air. I ask the students to look around and decide if the particles are close together or far apart and to decide if there are a few or many. When they conclude there are many and they are far apart, we move on.
