Safety notes

Electricity generation: Part 1

Activity 1 - Balloons

  • Make a show of pretending to burst one before you do it so that they do not get a fright.
  • Take care not to burst one near a child so that no one is stung with the springing rubber. Or that one is burst close to a child’s ears.

Activity 2 – mechanical toys

  • Check there are no sharp edges to cut fingers etc.

Activity 3 – household appliances

  • If you plan to connect these to the mains they should have been given a Portable Appliance Test. (PAT test)
  • Items borrowed from the school should already have been tested.

Activity 11 - Lemon battery

  • Take care to ensure that lemon juice is not squirted at a child when a nail or coin is inserted in a lemon. If a child gets lemon juice on their hands it should be washed off as soon as possible in case they rub their eyes. Since children may wish to copy this at home, stress the importance of asking an adult to use the knife to make the slit in the lemon for the coin.
  • Care should be taken with the crocodile clips so that fingers are not trapped.

Activity 14 - Hand generator

  • Ensure that the bung securing the end of the tube is tightly fastened on. After showing the magnet to the children, tape the bung in place.
  • When shaking the tube, place a thumb over the end so that the magnet does not fly out.

Neodymium Magnets

  • Neodymium Magnets are dangerous because of their strength and the fact that they easily shatter and produce sharp fragments.
  • They should all at times be treated with respect and not left with children unsupervised. Nor should primary-age children be allowed to handle them.
  • There is a danger of nipped flesh if they are allowed to snap together.
  • They should be kept away from electronic apparatus and credit cards, digital cameras, watches, mobile phones, pacemakers etc.
  • Care should be taken to ensure the magnets do not jump and become attached to a steel shelf bracket or furniture frame and so be lost.
