Forces and space: Unbalanced forces
Unit outcomes
Pupils who are secure will be able to:
- Describe gravity and its effects.
- Describe the relationship between mass and gravity.
- Describe air resistance and its effects.
- Describe friction and its effects.
- Describe water resistance and its effects.
- Describe the relationship between surface area and air and water resistance.
- Explain how to make an object aerodynamic or streamlined.
- Describe the effects of levers, pulleys and simple machines on movement.
When working scientifically, pupils who are secure will be able to:
- Analyse predictions, data and anomalies to write a conclusion.
- Plan a fair test to investigate air resistance.
- Write a method.
- Evaluate a method and judge the degree of trust.
- Design a results table.
- Calculate the mean average from repeat data.
- Draw and annotate a diagram.
- To draw an accurate line graph.
Please note that Kapow Primary Science lessons are designed to be 1 hour and 30 minutes long to reflect the requirements of a core subject.
