Students classify six common substances as either a solid, liquid, or a gas. Students then group these substances into elements, mixtures, or compounds.
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 five diagrams of different arrangements of atoms. They select which diagram represents water, graphite, oxygen, and carbon monoxide.
