Are you sick of looking at your students' books and seeing incomplete notes and incorrect diagrams for expansion and contraction? If so these expansion and contraction worksheets are perfect for you! Scaffolded notes for students to fill in key words and diagrams for expansion and contraction of matter in relation to particle theory.

Students will gain an understanding of the importance of heat energy in terms of expansion and contraction with application to everyday examples.

This resource zooms into solids, liquids and gases at a particle level to understand why they expand and contract with the addition or removal of heat.

Suitable for middle school science.
