This week in science, we are looking at how friction works as a force. Do you know what friction is? Have you heard of it before? Have a go at writing down what you think it is before watching the video below. After watching the video, have a go at writing down what you know friction is now or when you might see it in action.

Have a go at this investigation- only if you have the resources! It uses a toy car but you could use anything that rolls, a ball, marble or other toy with wheels. You also need some sort of ramp- a plank of wood, tray, large book would do the job. Then a variety of surfaces for the item to roll over some rough, some smooth for variation. You could either alter the height of the ramp as it suggests on the work sheet, or maintain the same height but time how long it takes each item on the different surface to get to the bottom. Both methods will test the effects friction has on movement. If you are unable to try the experiment then you can predict what might happen and discuss it with someone in your household.

If you are unable to complete the experiment at home- please don't worry!


Have a go at this:


Place these surfaces in order of slowest to fastest. So, the slowest surface, is the one that the car would travel the slowest down the ramp so in the longest amount of time. The fastest surface, is the surface that would allow the toy to travel the fastest down the ramp so in the least amount of time.


Order the surfaces from slowest to fastest:

  • wood
  • carpet
  • cardboard
  • sand paper
  • T-shirt material (cotton)
