This lesson introduces pupils to elastic materials, spring extension, and the foundations of Hooke’s Law. Students explore which materials return to their original shape, investigate how extension changes with applied force, and learn how to plot and interpret force–extension graphs. The lesson builds strong scientific thinking skills through prediction, measurement, graphing, and identifying the limit of proportionality.

Clear modelling, structured practical guidance, and visual graph interpretation make this lesson accessible and engaging for Year 7 learners.
