###### Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about pressure (GCSE and Key Stage 3)

*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/ *

#### Atmospheric pressure

Key Stage 3 practical demonstration and written task on air pressure using the egg in a bottle. Students describe and explain what happens to the air particles during the egg in the bottle demonstration. Introduce students to sequencing in time (initially, subsequently, penultimately, finally) to help structure the sequence of events. You can focus thinking and scaffold writing by showing the stages of the demonstration that need to be explained using the image above. (PDF)

#### Pressure in fluids at depth and altitude

GCSE and Key Stage 3 worksheet on pressure in liquids and gases. Students use the particle model to explain pressure in fluids and consider what happens to air pressure at different altitudes and water pressure at different depths. This resource was contribute by Terry Baylis. (PDF)

#### Pressure in gases

Go to the particles page for a worksheet to explain motion and pressure in gases using the particle model.

#### 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)
