Episode 2 — Physical Properties of Matter

Strength

Learners will be able to:

• Explain strength as a physical property of a material and predict which everyday materials (e.g. paper, cardboard, corrugated cardboard) are stronger or weaker • Plan and carry out a simple investigation to test the strength of different paper samples, and use the results to evaluate their predictions • Explain why the strength of a material must suit the function of the object it is used to make
