One of the first things we do when decorating for Christmas is put up lights, but how do they work? And what's the difference between the "old fashioned" type of light bulbs and the new LED bulbs? What does LED even mean? This week Cheryl learns about the different types of bulbs, why LEDs are more energy efficient, and how the same bulbs can be both white and colored! It's never too late to learn about the world around you.
This is part of the Holiday unit.
