The Shocking Truth about Energy
PROJECT IDEA: Create math word problems based on energy-saving ideas. For example:
How many light bulbs does your house have? Estimate how many hours a day each one is “on.” Add up the hours to see the total “light-hours” for your house each day. How many light-hours would they shine each year?
Energy sources from muscle power to fossil fuels to solar, wind, geothermal, and plant power are explored with the help of a bolt of pure energy named Erg and a gaggle of gadgets including kitchen appliances, toys, and tools. Helpful tips for saving energy are included.
Art: Handpainted line work and digital painting.
