Berkeley's Lawrence Hall of Science wrote: "Children learn about every aspect of energy--its various types (e.g. solar, magnetic.), forms ( e.g. kinetic vs. potential), and uses. In addition, this kit teaches children about the choices we face in the future: Where will our energy come from? How can we make the best use of our resources? What is best for our environment and health? As with the entirety of the ScienceWiz line, the kits are accompanied by a booklet written specifically for children. The writing is clear, concise, and easily engaging, complimented strongly by clever illustrations."
