Forces, Stretching and Hooke’s Law — Interactive Lesson (Ages 11–14)

Springs, elastic bands and bungee ropes all follow the same simple rule. This 18-slide interactive lesson on Hooke's law takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Forces, Stretching and Hooke's Law in KS3 Science

Pupils describe how pairs of forces stretch, squash, bend and twist objects, then calculate extension from original and stretched lengths. They use force = spring constant × extension, predict extensions for new forces, read force–extension graphs and explain the limit of proportionality and the elastic limit, before planning a fair spring experiment.

What Pupils Will Learn

• Describe how forces can stretch, squash, bend or twist objects.
• Measure extension correctly.
• Use Hooke's law: force = spring constant × extension.
• Read a force–extension graph.
• Explain what the elastic limit is.
