Science at key stage 3    (Year 9)

Unit 9H: Using chemistry
Section 5: What types of new material are made through chemical reactions?

QCA

Objectives
Children should learn:
  • about the range of materials made through chemical reactions
  • about the stages of development of a new product

Activities

Outcomes
Children:
  • Use photographs, packaging, video material to illustrate to pupils the vast range of materials, including those in living systems, resulting from chemical reactions. If possible, invite a scientist, eg pharmacist, materials scientist, food scientist, to talk to pupils about what they do and how they develop new products. Supplement this by providing pupils with case studies of the development of a new product, eg drug, plastic, textile, foodstuff. Ask pupils to choose a product and make a summary of the key stages of development.
  • name a range of materials in living and other systems resulting from chemical reactions
  • describe the key stages of development of a new product

Points to note
  • Some schools may be able to arrange a visit to an appropriate workplace. It may be helpful to ask pupils to prepare questions to ask before any visit.
  • Information can be obtained from a range of sources, eg publications of the Royal Society of Chemistry and the Chemical Industry Education Centre at the University of York.
