Science Experiment: Steady Hand Game

In this experiment we made a working steady hand game.  A steady hand game requires you to move a hook along the length of a wire, without the hook actually touching the wire.  If it does touch, the game will make a noise or show a light, and that means you've lost the game.

We used electrical components to make a circuit.  I learned that electricity needs to flow (like water) in order to work, which means it needs a way in and out of each component.  I also learned from this that when the electrical components are all connected properly, the circuit is closed, and when you disconnect something the circuit is open.

These are all the pieces before we started:

After following the instructions we had made a working steady hand game with a buzzer!

The next picture shows the buzzer and light connected in series.  Only the buzzer worked, as the buzzer made too much resistance for the light to work too.  We then connected the light and the buzzer in parallel, and they both worked at the same time!

I learned a lot from this, but I really just wanted to play the game!
