Elastic potential energy lesson

Elastic potential energy lesson with questions and answers. Lesson objectives are: State what the limit of proportionality is, describe what elastic potential energy is and explain what extension is and apply the equation for elastic potential energy. 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 - Introduction to elasticity and its meaning
Slide 4 - Definition of limit of proportionality
Slide 5 - Mini plenary. Random name animation used to test pupils’ recall of limit of proportionality definition
Slide 6 - Definition of elastic potential energy
Slide 7 - Mini plenary. Pupils are asked to describe scientifically what an image is showing (a sling shot being pulled back and launching a stone). Answer animates onto screen - elastic potential energy being transferred to kinetic energy
Slide 8 - Introduction to elastic potential energy equation with units
Slide 9 - Explanation of what extension is and how to calculate it (some questions do not state the extension in an obvious way)
Slide 10 - Elastic potential energy worked example 1 (answer animates onto screen in stages)
Slide 11 - Elastic potential energy worked example 2 (answer animates onto screen in stages)
Slide 12 - ALT (Applied learning time). Differentiated elastic potential energy calculation questions (9 in total). Gold, silver and bronze levels of difficulty (Silver and gold require pupils to rearrange the equation)
Slide 13 - ALT review - all answers animate onto screen
Slide 14 - Plenary. Elastic potential energy GCSE exam calculation. Answer animates onto the screen in stages
