Science / Design & Technology KS2: Investigating air and water resistance

Children from Links Primary in London investigate air and water resistance.

They experiment with different shaped objects, streamlining them to make them travel quickly through the water. But can they make the shapes fast and stable?

This clip is from the series The Bloodhound Adventure.

Teacher Notes

This clip could be used when learning about natural forces, especially when investigating friction.

You could stop the clip after an experiment is introduced and ask the pupils to make a prediction about the outcome.

Will a stronger force make the object travel faster through the water? What kind of shape will cut quicker through the water? Then continue the clip and invite the children to comment on their predictions.

You could repeat the experiments and challenge the children to try out other shapes.

You could also look at friction and surfaces.

Hand out building blocks and invite the children to move them across different kind of surfaces, eg concrete, wood, sand or Teflon. Ask them to describe their experiment.

Curriculum Notes

This clip will be relevant for teaching Science or Design and Technology at Key Stage 2 in England, Wales and Northern Ireland, and Level 2 in Scotland.
