What you will learn
- Identify pushes, pulls, friction, gravity and air resistance
- Plan a fair test changing one variable
- Record results in a table and draw a bar chart
- Explain results using force ideas
Helpful to know first: Measure length in cm; Read a simple table

Practise — check a common mix-up
Heavier objects always fall faster.
In a fair test you change…
Apply / Create — Fastest Surface Investigation
Test how far a toy car travels on three surfaces. Record, chart and explain using friction.
Evidence type: experiment record · accessible alternative always allowed (speak it, draw it, or show an adult).
How it is judged (rubric)
- Beginning: Tried surfaces
- Developing: Table completed
- Secure: Fair test, table, chart and friction explanation
- Extending: Repeat readings, evaluation of accuracy
Explain — say what you did
