Design and Technology (D&T) KS2: How to make a structure waterproof

Follow two primary-aged pupilds as they build a den in their garden and learn how make it waterproof.

This short film is an ideal introduction to any design and technology unit dealing with construction.

It demonstrates practical activities that pupils can carry out in the classroom, or at home, to make something waterproof.

Teacher Notes

This short film is an ideal tool to introduce pupils to techniques that can be used to make structures waterproof.

As they watch the film, pupils can give their own thoughts on why they think certain materials offer more protection from water that others.

Pupils can also try to relate their ideas to real life and everyday objects around them, linking theory to practice.

Points for discussion:

  • What considerations have to be taken into account when building a structure that has to be waterproof?
  • Which materials are the best for making something waterproof?
  • How can we make something more waterproof?
  • What would happen if we were not able to make things waterproof?

Suggested activities:
After watching the film, you could work with pupils to assess how waterproof structures are in different contexts.

Pupils can be given the opportunity to build their own waterproof structures, make predictions about how waterproof they will be, and then test their theories.

Pupils could carry out practical activities to make things more or less waterproof. They could relate these explorations to everyday objects, or research different structures in books or on the internet.

Curriculum Notes

Suitable for teaching design and technology (D&T) at KS2 in England, Wales and Northern Ireland, and 1st and 2nd level in Scotland.
