ScienceWiz(R) Inventions: This multi-award winning book and kit uses everyday materials to build * A spinning motor * A clicking telegraph * A light-flashing generator * A real radio. The use of simple materials (no plastic required) helps to demystify the "why" as well as the "how." The step by step, fully-illustrated, 40 page book makes the projects very doable and the explanations easy to understand. Imagine building a working radio using only aluminum foil, wire and a diode. That's it. No battery required. Now make a spinning motor using only paper clips, a magnet, a bit of wire and a…mehr

ScienceWiz(R) Inventions: This multi-award winning book and kit uses everyday materials to build * A spinning motor * A clicking telegraph * A light-flashing generator * A real radio. The use of simple materials (no plastic required) helps to demystify the "why" as well as the "how." The step by step, fully-illustrated, 40 page book makes the projects very doable and the explanations easy to understand. Imagine building a working radio using only aluminum foil, wire and a diode. That's it. No battery required. Now make a spinning motor using only paper clips, a magnet, a bit of wire and a battery. Light a bulb by spinning a coil of wire next to a bar magnet. Make a telegraph click and send coded messages to a friend using just two paper clips, a nail, wire and a battery. Every day materials, indeed! These are all inventions with coils. With these inventions you can explore the discoveries of Michael Faraday and Nikola Tesla, two scientists whose work led to the creation of the electrical grid.

Autorenporträt
Penny Norman, Ph.D. earned a doctoral degree in Biophysics from U.C. Berkeley. She became involved with the development of primary grade science materials through volunteer work, which she began as her own children started school. During this process she became deeply concerned about the limited exposure of elementary age students to the physical sciences.Her concern has translated into a 20 year effort to test and revamp science materials for the primary grades. Her work with children developed into a product line initially under the auspices of grants from the National Science Foundation and the Franklin Foundation. Her published titles reflect Dr. Norman's extensive testing and involvement with children and teachers and her love and commitment to both.
