Secondary Magazine

How fast can I go?

Click here to download the sheet to accompany
this activity (in PDF format).

Pupils work in pairs and have the image sheet as a visual stimulus. Pupils first need to define the problem that they are going to work on – allow them some time to look at the images and work out what the problem is. (The speedometer on the car – an Alfa Romeo Spider – reads km/h and British road signs are given in mph, so how fast can they drive in a 20mph zone etc.)

Working on large sheets of paper with felt pens, pupils can be encouraged to recall a miles-km conversion fact, and from this draw a spider diagram showing lots of useful related facts (if I know this then I also know...) similar to the one shown.
Draw attention to the fact that 0 miles = 0 kilometres.

From this, pupils can draw a conversion graph.

Finally, using the graph, ask pupils to write some guidelines that might be useful for the driver of the car.
For example:

  • In a 20mph zone you can drive at ...... and be within the law.
  • In a 30 mph zone… etc.

this activity (in PDF format).

Pupils work in pairs and have the sheet as a visual stimulus. Using the information on the sheet, pupils can write some statements about the car.

For example:
  • the temperature of the engine is low, so it hasn’t been driving long;
  • it has done 73km since it was last re-set;
  • the driver can’t be going far because the fuel gauge is under half full;
  • it was travelling around 80km/h when the picture was taken;
  • the oil gauge reads...
  • the battery charge is...
  • the rev counter...
  • acceleration...
Encourage pupils to share their statements and build up a mental picture of the car and its journey rather than just a set of readings.
