RECAP THE CONCEPTS

Strength

  • A strong material does not break easily (e.g. wood).

  • Strong materials are able to support heavy loads without breaking.

  • A weak material breaks easily (e.g. glass).

Flexibility

  • A flexible material can be easily bent without breaking.

  • A material that is not flexible is stiff.

Buoyancy

  • Materials with a lower density than water will float on water (e.g. wood).

  • Materials with a higher density than water will sink in water (e.g. steel).

Absorbency

  • Absorbent materials absorb water well.

  • A waterproof material does not allow water to pass through. It also does not absorb water.

Transparency

  • Transparent materials allow most light to pass through them.

  • Translucent materials allow some light to pass through them.

  • Materials that do not allow light to pass through are opaque.

Conductivity of Heat

  • Good conductors of heat (e.g. metals) allow heat to pass through easily.

  • Some materials such as fabrics, wood, rubber and plastic are poor conductors of heat.
