Lesson details

Key learning points

  1. Deforming materials changes the shape and not the state.
  2. Timber veneer can be deformed by laminating.
  3. Vacuum forming is a deforming process for polymers.

Keywords

  • State - the form of matter; gas, liquid or solid

  • Malleable - can be pressed into shape without breaking, usually in reference to metals

  • Brittle - breaks or fractures easily without deforming or stretching

  • Laminating - sticking several layers of material together

  • Plasticity - can be pressed into shape without breaking, usually in reference to polymers

Common misconception

Laminating is when paper or card are covered in clear polymer.

Laminating means sticking several layers of material together, the clear polymer coated paper or card process is encapsulation.

This lesson is a great opportunity for students to get involved in practical tasks. Laminating and vacuum forming both require moulds which you could prepare in advance.
