Dark and stormy night

making_a_torchYear 8 students have just begun a unit of work on electricity, by making a circuit and a switch from simple materials, such as aluminium foil, drawing pins and paper clips. Their next task is to make a torch that can be operated with one hand. Imagine you are driving with Dad in the car on a dark and stormy night. The car breaks down and Dad has to walk to the nearest house, about an hour away. You scratch through the glove-box and behind the car seat and this is what you find:

  • 2 batteries
  • cardboard tube
  • aluminium foil
  • paper clips
  • drawing pins
  • sticky tape
  • copper wires
  • a globe from the overhead light

Can you make a torch, with a switch, that can be turned on and off with one hand? Your torch will be judged on it’s reliability, ease of operation, brightness of beam and sturdiness of the connections.

Quia – create your own quizzes, games and surveys.

My American colleague, Mrs Laguna, is also a member of Quia, where you can create any of thirteen different activities (from battleship to scavenger hunts), as well as quizzes and surveys. As well as creating your own activities, as a member you can browse the activites of other teachers.

Here are a few for my year 9 Science class to try:

And for year 7 Maths (decimals, fractions and percentages):
