Resources

Resources include:

  • secondary sources, eg video, CD-ROMs, illustrating the burning of a range of fuels, eg household waste in a power station
  • equipment for making simple voltaic cells
  • information about chemical heaters, eg meals for climbers, hand warmers for Arctic explorers
  • secondary sources or artefacts illustrating a range of materials, eg textiles, plastics, pharmaceuticals, toiletries, processed foods
  • case histories illustrating the development of a new product, eg vacuum cleaner, food product
  • simulation software illustrating the rearrangement of atoms in chemical reactions
  • secondary sources providing information about Priestley, Lavoisier and earlier ideas about burning
