How many home schoolers does it take to change a light bulb?

First, mom checks three books on electricity out of the library, then the kids make models of light bulbs, read a biography of Thomas Edison and do a skit based on his life. Next, everyone studies the history of lighting methods, wrapping up with dipping their own candles. Next, everyone takes a trip to the store where they compare types of light bulbs as well as prices and figure out how much change they'll get if they buy two bulbs for $1.99 and pay with a five-dollar bill. On the way home, a discussion develops over the history of money and also Abraham Lincoln, as his picture is on the five-dollar bill. Finally, after building a homemade ladder out of branches dragged from the woods, the light bulb is installed. And there is light.
