CP13a Bending and stretching

Complete GCSE Physics lesson on bending and stretching, with PowerPoint, scaffolded worksheet and assertive monitoring resources.

A ready-to-teach Dr B Science CP13a: Bending and Stretching lesson, designed for Pearson Edexcel GCSE Combined Science and easily adaptable for other GCSE specifications.

The lesson develops understanding of how forces deform objects, elastic and inelastic deformation, extension, and force–extension relationships for springs and rubber bands.

The lesson follows a structured I Do → We Do → You Do approach with explicit modelling, Show Me Boards, Cold Call, guided practice, independent application and assertive monitoring.

Covers:

• Stretching, bending and compression
• Forces causing deformation
• Elastic and inelastic deformation
• Particle model of deformation
• Original length, stretched length and extension
• Force–extension graphs
• Linear and non-linear relationships
• Direct proportionality
• Springs vs rubber bands
• Interpreting unfamiliar graphs

Included:

• Complete PowerPoint with detailed presenter notes
• 4-page scaffolded You Do worksheet with vocabulary, sentence starters and structured support
• Assertive monitoring teacher sheets for each key independent task
• Pupil-facing monitoring codes, WAGOLLs and feedback prompts
• Retrieval Do Now and explicit vocabulary teaching
• I Do modelling and We Do guided practice
• Show Me Board, Turn & Talk and Cold Call activities
• Independent graph interpretation and challenge questions
• Exit ticket linked to the key knowledge

The assertive monitoring resources target common misconceptions around deformation, elastic/inelastic behaviour, extension, graph shape and direct proportionality, supporting rapid feedback and responsive reteaching.

Ideal for Year 10/11 GCSE Combined Science, mixed-attainment classes, adaptive teaching, GCSE revision and lesson observations.
