In the past few decades, light bulb technology has gotten better. Not only have compact fluorescent light bulbs become available and affordable, but federal guidelines have caused incandescent light bulbs to become more efficient, too. Readers learn about both kinds of light bulbs, how they work, and their differences. Theyll find an introduction to important science curriculum concepts such as circuits and environmental impact. The main content traces electricitys path from the power plant all the way to the lamp in a house, and a colorful diagram illustrates this process as well.
