- What you need: Card eg ceral box, battery, wireswith crocodile clips, bulb or buzzer, paper fasteners
- Think of three questions and three answers OR three statements to match
- Attach the battery to the bulb/buzzer
- Attach a wire to the other end of the battery and put through the Question 1 hole
- Attach a wire to the other end of the bulb and attach to the Question 3 correct answer on the back
- On the back , attach a wire to the 1st correct answer and loop it through the Question 2 hole
- On the back, attach a wire to the 2nd correct answer and loop it through the Question 3 hole
Now a complete cicuit will be formed only when the correct answers are connected to the questions.
Test it out first to check that it works before you get anyone else to soslve it
Tidy it up by sticking the battery and spare wires behid the board. You could also make a hole for the buld or buzzer to pike through.
Other ideas – put a push switch in the circuit so that the player has to puch to check their answers.
