"This innovative guide offers students hands-on learning opportunities with electro-magnetism and electronics. Students will see home-made microwaves, sparks, and logic circuits with equipment they create from inexpensive materials. In the process, abstract concepts will become familiar. Students will also discover that real-world problems are many-sided and yet observable and measurable. Students become designers, inventors, and doers; in trying to answer first questions, they will learn that there are many more to define and address." "Thirteen carefully chosen and tested experiments are designed to safely introduce students to the physics of charges. In the process, abstract concepts and relationships will become more real and more intuitive."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved
