Making loops(Activity)



Using simple electric circuits

This is a design and make activity through which you can explore the idea of a complete circuit with the children and help them to build a circuit using the available laboratory equipment.


What the activity is for

  • To capture interest.
  • To review the idea of a complete circuit.
  • To engage children in designing and making circuits using appropriate laboratory equipment.
  • To encourage children to talk and think about simple electric circuits.

  • What the activity is for

  • batteries, buzzers and bells
  • connecting wires
  • copper wire, copper strip, stiff card, plastic foam or clear tape

  • What happens during this activity

    Start by demonstrating with a simple circuit containing a battery and a buzzer or bell that a complete circuit is needed for a buzz or ring. Then explain that the children are going to use this simple principle to design and make one of three devices:

  • A burglar alarm for the classroom door: open the door and the bell rings.
  • A pressure pad alarm: stand on the mat and the bell rings (or sit on the chair and the bell rings).
  • A steady hand tester: touch the wire with the loop and the bell rings.
  • Divide the children up into teams of three or four and allocate a device to each team. Insist that the teams spend 10 minutes in talking through and drawing out their ideas before starting to work with the equipment. Equipment and materials should be set out so that the teams can collect whatever items they think will be useful. Be prepared for requests for additional items!

    Allow plenty of time at the end of the session for each team to:

  • Describe their invention.
  • Explain how the device works.
  • To add to the sense of occasion, you might get some children to invite another member of staff into the lesson to try out the alarmed chair!

    Experience has shown that the children really enjoy this activity and that it provides an excellent opportunity for talking around basic electric circuit ideas. Be prepared for children insisting that their door alarm is left in place, and then showing their friends from other classes how it works at break time!
