Scheme of work — at a glance

Nine lessons take pupils from “what is friction?” to levers, pulleys and gears — with a full plan → investigate → evaluate parachute enquiry and a water-resistance investigation building working-scientifically skills along the way. Each lesson runs the same structure — Arrival → Starter → I do → We do → Independent → Exit — in about 44 minutes, differentiated across three primary tiers.

National Curriculum coverage

  • Explain that unsupported objects fall towards the Earth because of the force of gravity acting between the Earth and the falling object.
  • Identify the effects of air resistance, water resistance and friction, that act between moving surfaces.
  • Recognise that some mechanisms, including levers, pulleys and gears, allow a smaller force to have a greater effect.

Working scientifically

  • Planning enquiries and recognising and controlling variables where necessary (L3, L6).
  • Taking measurements with increasing accuracy and precision, and repeat readings (L4, L7).
  • Recording data, reporting findings, and using results to draw conclusions and suggest improvements (L5, L7).

Prior learning & next steps

Builds on (Y3): forces and magnets — pushes and pulls, and how things move on surfaces. This block introduces pupils’ first formal fair and comparative tests and the language of variables.

Leads to (KS3): forces, gravity and weight, speed, and simple machines.

How each lesson is built

Every lesson is a single interactive web page: six-phase structure with on-screen timings; three tiers on the four pupil-facing tasks; a short teaching video; a self-contained animation targeting the lesson’s key misconception; TA Focus and Cold Call prompts; and a one-click print pack.

Differentiation tiers map to attainment bands: 🌱 Seedling = working towards · 🌿 Sapling = expected · 🌳 Oak = greater depth.
