1. Check that everything on the board is working by touching the 2 loose alligator clips together.

The bulb will go if everything is working. If the bulb does not go, tell the teacher now.

Whakamätauria mena kei te ora ngä mea katoa o te papa püaho [bulb board], mä te whakapä i ngä rawhi kakati [alligator clips] e rua.

Mena e ora ana, ka kä mai te püaho. Ki te kore e kä mai te püaho, me körerohia atu ki te kaiako inäianei.

   

Inside the cardboard some of the wires are joined to other wires. Each wire might be joined to 1 other, 2 others, or no others.

Use the board with the battery and bulb to find out which wires are connected.
