Why cast it

This is one of a set of resources produced in conjunction with the engineering company Arconic. The resources are designed to support teaching of key engineering concepts at both key stage 3 and key stage 4, including the new GCSE in Engineering. This resource focusses on the understanding of the reasons why casting is used to make products.

In this activity, on outline is given of the casting process and the reasons why it is used to make products. Learners then carry out a practical activity to reinforce their understanding of why casting is used to manufacture some products rather than subtractive (wasting processes). This activity involves the use of moulding materials to simulate manufacture using two process types, for comparison: a moulding/casting process and manual wasting.

This could be used as a one-off main lesson activity or as an introductory lesson to a wider unit of work involving a casting activity.

The activity sheet includes teacher notes, guidance, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved UK nations; England, Northern Ireland, Scotland and Wales.
