Learn about electricity circuits as you experiment with conductors and power sources in this fun, interactive activity. Find out what materials conduct electricity better than others. Try lighting the bulb by putting different objects and materials such as a coin, cork, rubber, key, chalk, plastic or wire into the gap in the circuit. What happens to the bulb brightness when you add another bulb to the circuit? Do you notice a difference in brightness if you have just one bulb but two batteries? Play around with different combinations, learn more about electricity and enjoy this great science game for kids.
