Energy, electricity and forces
Find out how this strand develops pupils' use of quantitative evidence in the analysis and interpretation of data, through two substrands: 'Energy transfer and electricity' and 'Forces'.
Energy transfer and electricity
This substrand is based on the transfer model, as opposed to the transformation model. This is because the transfer model provides a stronger foundation when moving from Key Stage 3 to Key Stage 4. However, pupils can consider the strengths and weaknesses of both models, so that they are aware how textbooks and exam questions have confused the two. While pupils are studying this substrand, they consider energy transfer related to the following:
- biological systems.
Pupils will already have had a wide experience of forces, having learnt about types of force, their effects and how to measure them during primary education. Because of this foundation, the 'Forces' substrand begins with abstract ideas, in which models are used to develop understanding about forces in action.
