NEW AQA Physics (2016) - Pressure and surfaces

This lesson is designed for the NEW AQA Physics GCSE, particularly the ‘Force and pressure’ SoW.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience

The lesson starts with an introduction to pressure, and identifies the factors which affect pressure - how much force is applied and the size of the area on which the force is applied, this is demonstrated by the example of caterpillar tracks on vehicles such as tractors/bulldozers. The next slide shows some pictures of objects such as ice skates, skis, tractor and stiletto heels, students will need to describe the pressure exerted on the ground by these objects. The following slide provides a description of how these objects exert pressure on the ground as a summary. Students can assess their knowledge of this with the quick check questions on the next slide, the answers are included so students can assess their work.

The calculation for pressure is now introduced to students, including a worked example. Students will then be presented with a range of questions for them to practice using the calculation, the answers to these questions are on the next slide so students can self-assess their work.

The next activity is an investigation, students will draw the outline of their feet onto 1 cm squared paper and they will use the area and their weight to calculate the pressure they exert on the ground. The last task is to complete a worksheet on pressure, the mark scheme is included for students to self-assess their work at the end of the lesson.

The plenary task is for students to discuss what they have learned this lesson with the person next to them.

All resources are included. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated.
