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.

Year 8 Science: Simple Circuits

This week we are starting a unit of work on Electricity – you will learn about current and voltage, series and parallel circuits and create your own torch using some readily-available items (cardboard tube, aluminium foil, small light globe, copper wires, cardboard, masking tape and paperclips). Your torch will be asessed for it’s ability to direct a beam of light, turn on and off and be easily operated with one hand.
