• Jack-in-a-box type toy
    E.g. a tin stating it contains peanuts but which has a springy ‘worm’ in it. Available from on-line novelty suppliers or novelty shops.

Activity 2: Elastic and inelastic properties

  • A pack of ‘fashion string’ as available from toy shops (PVC ‘string’ used to make plaited bracelets etc). Cut into lengths of about 30 cm so there are 2 pieces for each group.
  • Fishing pole elastic.
    Available from anglers’ suppliers. Lengths of ~10 metres are sold for about £2 ( Buy 2 lengths and save one for use in activity 3).Cut sufficient 30 cm lengths so that there is one piece for each group of 4 children.

Activity 3

  • A long length of fishing pole elastic. Tie a loop at each end to serve as good handles to hold the elastic firmly.

Activity 4

  • Packs of stretchimals or similar latex toys available from on-line novelty suppliers or novelty shops. Enough for two individual items of different shape for each group of children.

Activity 8

  • Slinky spring
    Available from school science labs or from on-line novelty suppliers or novelty shops.

Activity 9

  • 6 springs
    Which stretch several centimetres when subjected to a 1 newton load.
  • (Any such available springs could be utilised. Alternatively, springs might be borrowed from school science labs.)
  • Objects of various weights that can be suspended on the springs
    E.g. a lime, a lemon, an orange and a grapefruit. These are familiar objects and their size is closely linked with load on the springs.
  • NB: Before the visit make string loops or other simple arrangements so that objects can be suspended from the springs. If fruit is used, before the session, tie tapes round the fruit so that it can be suspended from the springs.

Activities 10, 11

  • Examples of familiar items with springs in them.
    For example: toys including wind-up toys, sports equipment such as tennis racquets, etc. NB: Examples of toys which have springs in them change rapidly. Look for examples that are fun and novel!
