Food prep materials challenge

Science Year 5
This unit is part of Year 5 Science Music Festival Materials

Objectives

All food prep areas need to meet health and safety standards as well as be made from the best (and hardest) materials around. Your job is to investigate and make recommendations for the right material options.

Science Objectives
i) Compare and group together everyday materials on the basis of their properties, including their hardness, transparency, and conductivity (electrical and thermal).

ii) Give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials, including metals, wood and plastic.

Working Scientifically

  1. Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.
  2. Record data and results of increasing complexity using tables and scatter graphs.
  3. Report and present findings from enquiries, including conclusions and explanations of and degree of trust in results, in oral and written forms such as displays and other presentations.

You Will Need

Lesson Planning

Teaching

  • Plan and carry out an investigation on a range of materials to test for hardness.
  • Present results, identifying the hardest materials that are also fit for purpose as a food prep surface.

Activities

  1. List properties suited to food prep surfaces.
  2. Plan and carry out an investigation on a range of materials for their hardness.
  3. Record findings in table and scatter graph form.
  4. Select the hardest materials from a range of materials that are also smooth and easy to clean.

Investigation - exploring
Investigate hard materials suitable for food preparation.
