      Lesson details

      Learning outcome

      I can investigate the properties of materials that would suit the purpose of my design.

      Key learning points

      1. Fabrics have different insulating properties.
      2. Fabrics have different levels of water resistance.
      3. Fabrics have different levels of strength.
      4. Designers need to consider the sustainability of fabrics.
      5. Fabrics are chosen for their properties.

      Keywords

      • Properties - words used to describe what a material is like

      • Insulating - stops heat from escaping

      • Waterproof - no water can get through at all

      • Water-resistant - doesn't soak up water easily

      • Sustainability - using what we need, while protecting the environment so there is enough for the future

      Common misconception

      All fabrics have the same properties.

      Different fabrics have different properties which must be considered when selecting fabrics for designs.

      Teacher tip

      Insulation test - depending on conditions, this may need to be set up in the lesson and observed over more time.

      Equipment

      Fabric scraps, ice cubes, stopwatch or timer.
