Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about pressure (GCSE and Key Stage 3)
Spend time making sure students have an understanding of the concepts of surface area and force before introducing the equation p=f/a.
This short clip from Dragons’ Den can serve as a good starting point to help students conceptualise pressure, force and area. It is a nice example of how science can be used to improve the design of everyday products. Further information on this product can be found here: http://cleanheels.co.uk/
Calculating pressure using force and area
GCSE and Key Stage 3 worksheet on pressure, force and area. Students provide evidence to show why Heel Stoppers reduce the pressure exerted by both shoes. They use squared paper to calculate the area of a high-heeled shoe and the new area when the Heel Stoppers are connected. Students can quantify the effect of the Heel Stoppers by performing a series of calculations. Putting p=f/a in context ensures students are engaged and better able to see the relevance of their calculations. (PDF)
