Q: Mr. Johnson is stumped. Every other light on his string of holiday lights are out. Draw a diagram to explain what is wrong with Mr. Johnson's string of holiday lights. Use the words and symbols for: circuit, current, power source, and light.
A: series circuit
Feedback ("series circuit"): Mr. Johnson's lights have two strings of lights both on a series. One of those circuits are out.

Q: Describe the positive and negative impacts that electricity has on the natural world as more and more engineered products and services are created and used. To put it another way, how is the world different now because of electricity than it was in your grandparent's day?
