The Buzzer Game
Equipment
:
We used a coat-hanger,
styrofoam, wire, a 9v batteries, a buzzer and insulating tape.
Method:
First
we got a coat hanger and asked an adult to cut off the top of it and bend it; we
used that for the hook. Then we got
the rest of the hanger and bent it into a funny shape.
After that we used styrofoam to stick the funny shape into.
Then we made a circuit. It
was like this, the battery was connected to the hook by a wire and the other bit
of the battery was connected to the buzzer and then the buzzer was attached to
the funny shape. The circuit is
completed when the hook touches the funny shape.
Result:
It turned out perfect. Everything worked with flying results. By N, C, E
