Complete lesson PPT with learning outcomes, new knowledge and activities detailed on the slides. The resource is designed to be used with the Activate C1 1.2 Practical sheet - Properties of solids, liquids and gases. The lesson is ready to go and is designed to support pupils aiming for developing and secure outcomes. All pupils should be able to identify a substance in its 3 states; most pupils should also be able to match properties of the 3 states of matter to the state; whilst some pupils should, in addition, be able to describe the properties of a substance in its 3 states. Challenge work involves using ideas about particles to explain the properties of a substance in its three states. Keywords include 'solid, liquid, gas, and states of matter'.
