Students draw diagrams to show the particle arrangement in a solid, liquid, and a gas. Students then describe the differences in arrangement and movement of the particles for each of these states.
Students are provided with drawings of three methods to collect gases and the characteristics of four gases. Students match the gases with the method of collection that would need to be used.
