Energy stores and systems lesson

Energy stores and systems GCSE Physics lesson including worked examples of energy transfers with answers, energy change diagrams, system definition, and what happens to the energy when the system changes. The lesson objectives are as follows: Define, with examples, what a system is, explain how a system can be changed and recall the main energy stores and explain what happens to the energy when a system changes. The slides are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides is as follows:

Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see above)
Slide 3 - System definition with examples
Slide 4 - Mini plenary. Random name animation used to test pupils’ recall of system definition
Slide 5 - Introduction to the three ways a system can be changed with an example of a man kicking a ball (Heating, work done by a force and work done when current flows).
Slide 6 - Mini plenary question: “This filament light bulb has just been switched on. How does this demonstrate a system being changed?” Answer animates directly onto screen
Slide 7 - Introduction to what happens to the energy when a system changes (When a system changes, energy is transferred from one energy store to another)
Slide 8 - KS3 recap of the main energy stores with photos to make the lesson more visual
Slide 9 - Example of energy transfer when an object is projected upwards. Answer animates as flow diagram with photo to make the lesson more visual
Slide 10 - Example of energy transfer when a moving object hits an obstacle. Answer animates as flow diagram with photo to make the lesson more visual
Slide 11 - Example of energy transfer when bringing water to boil in an electric kettle. Answer animates as flow diagram with photo to make the lesson more visual
Slide 12 - Mini plenary. Write down the energy transfers that take place when the following systems change:
A ball being dropped from a height and hitting the ground
A rubber band being stretched by a person and held
A handheld torch being used
A vehicle slowing down
Answers animate onto the screen as always
Slide 13 - ALT (Applied learning time). 3 mark exam question: Explain the energy changes in a book as it is resting on a shelf compared to when it is falling and hits the ground. Answer animates by paragraph onto the screen
This stage of the lesson is an opportunity for pupils to apply what they have learnt in the lesson
Slides 14-16 - Plenary. Short 1 and 2 mark exam questions with animated answers to wrap up an outstanding lesson and address any lingering misconceptions
