For our electricity science unit, we made electricity game boards. Our game boards worked by touching a wire to a brad and if you answered the question correctly a tiny light bulb would light up. This worked because we had foil on the back of the game board acting as wires for our game. We used a battery as our power source, and with wires we lit up the light bulb when the player touched the correct answer with the correct question. We decorated them in different ways with different themes. Some examples are; food, Disney, cats, video games, etc.
