Students demonstrate their knowledge of solid, liquid, and gas particles by drawing the particle arrangement for wax vapour, molten wax, and candle wax.
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.
Using provided data students decide which of three liquids would freeze if placed in a freezer. Students explain what happens to particles when they freeze and how the level changes due to freezing.
