The perfect science fair idea books. Spectacular Science Projects Janice VanCleave's Magnets
* How does a compass work?
* What is a magnetic field?
* How can you make a magnet with electricity?
Janice VanCleave's Magnets includes 20 simple and fun experiments that allow you to discover the answers to these and other fascinating questions about magnets, plus dozens of additional suggestions for developing your own science fair projects. Learn about magnetic poles using a bar magnet, paper, and string; about magnetic force fields with a compass, a pencil, and a sheet of paper; and much more. All experiments use inexpensive household materials and involve a minimum of preparation and clean up.

Editorial : From School Library Journal Grade 3-6-This collection of 20 science demonstrations illustrates basic properties of electricity, from static electricity to simple circuits and eletromagneticism. They all use household materials and include a brief explanation of what happened, some ideas for additional experiments, and a section called "show time" for science fairs. Experimental details are clear and written at a basic level. However, other than a clever use for clothspins in building circuits, most of the material is old hat. A bigger problem here, though, is in the packaging that promises "cook-book experiments" guaranteed not to fail. If only "real" science were that easy. Moreover, most science-fair judges downgrade projects they believe are basically copied from books such as this one. Generic black-and-white illustrations are scattered throughout the text; there is a glossary of terms but no list for further reading. Robert Gardner's Electricity and Magnetism (Holt, 1994) is a bet
It consists of, as the title would indicate, of questions concerning Business, Politics and Ethics. It got them reading on their own time. This story was fun to read and had my attention from the beginning. If you have read a few web-pages about vitamin D, you may already know everything here - vitamin D RDA is too low, many people are deficient, deficiency is associated with a number of illnesses, sunlight exposure will give you what you need but don't get sunburned, supplements can also help but are inferior to sunlight because you need to determine appropriate dosage. "The planner calls up a DMC, requests a proposal, and uses it to gather ideas and pricing. Dies ist zumindest die These des Autors. It also manages to tell the story in a straightforward and concise manner. I gave this book to my grandson as a Christmas gift because he is constantly asking, "Why?" The book description says it is for readers 4-8 and my grandson is only 3, but given his high level of curiousity, I though
