Once experimenters began to see events repeat in the world, they began to study the probability certain events would occur. You can build an electrical game to study probability.
Materials you will need:
4. Predict how many times the light bulb is going to turn on with a nickel, a dime, and a quarter.
5. Toss a dime at the grid 10 times and record how many times the light bulb turned on. Repeat the experiment with a nickel and a quarter. How often did each coin cover two aluminum strips and close the circuit turning the bulb on? Keep records of your results on a table like the one shown below and compare the results to your prediction. The more times you toss the coin the better you will become at estimating the probability of the coin closing the circuit.
