Lesson Planning
Teaching
- Investigate the effect ground friction has on movement.
- Identify an appropriate amount of friction for the safe onward journey of a bike.
- Use results to make further predictions and suggest further investigation.
Activities
- Investigate the effect of ground friction on the force needed to move a toy car.
- Recommend a ground covering that creates the right level of friction for the safe onward journey of a bike.
- Predict the likely speed of a bike on different surfaces, based on findings from friction investigation.
Investigation - problem solving/fair testing
Investigate friction.
Vocabulary
