New GCSE AQA Physics lesson on ’ Pressure and Surfaces’ written in line with new AQA Physics specification. All questions provided with answers within power point.
Starter looks at a balloon being pressed down onto a bed of nails - details of how to set this up simply with thumbtacks (obvious as it is) can be found in the notes box.
Following this a problem of dog trapped on thin ice is presented for pupils to come up with potential rescue attempts to avoid breaking the ice. The concept of pressure is consolidated with the example of thumb tack being pressed into a wall - the equation for pressure is then detailed.
To make use of the pressure equation an elephant and person in stiletto heels are compared mathematically to find which exerts the greatest pressure. Pupils are then guided to calculate the amount of pressure they exert onto the floor whilst standing.
The lesson is concluded with a set of review question.
Lesson Objectives:
- State what pressure is and be able to calculate it.
- Identify the units for pressure.
- Explain the relationship between pressure, force and area.
- Apply knowledge of pressure to different problems.
