Year 10 - Design and technology

Metal properties and processes

Product analysis: encouraging healthy lifestyles

Unit Summary

Pupils will analyse products to identify features in the products. They will also identify the materials, material properties and manufacturing processes used to create the products. They will conduct functional tests to collect and analyse data to inform design decisions.

Lesson Summary

You will learn to identify and justify the material and process used for a metal product.

Key Notes

  • There are two main stages in the sourcing of metal: mining and extracting.
  • There is an environmental impact to extracting and processing metals.
