What better way to do that than to play around with magnets? In this chapter, by playing with magnets, you'll learn about the types of magnets, magnetic materials, the properties of magnets, and how the Earth creates its own magnetic field.

Cutting, Splitting, and Stacking Circuits By: William C. Robertson, Ph.D. A chapter from Electricity and Magnetism: Stop Faking it! Finally Understanding Science So You Can Teach It Average User Rating: We've dealt with how basic circuits work, but there's more to using electricity than hooking up a battery and lighting a lightbulb. Electrical devices you use every day are a bit more complicated.

Electrical devices you use every day are a bit more complicated. For example, how can they make strings of Christmas tree lights that don't all go out when one bulb burns out? What's going on with those circuit breakers that switch off when you operate too many appliances at once? Answers to these and other questions as we proceed.

Other than that great guess work of yours, you might be wondering why the book is about electricity and magnetism. Is there any special reason to put these two areas of science together? The answer is yes. In fact, the connection between electricity and magnetism is so strong that you can actually view them as the same thing.

Understanding the operation of electric circuits and the devices that go into circuits requires a basic understanding of the scientific models of electricity and magnetism. To truly understand electric circuits, there's no substitute for physically messing around with them. This chapter provides you with the opportunity to let your "inner scientist" shine through as you conduct experiments using special software that can be downloaded from the NSTA Web site.

For example, what's up with high-voltage power lines, why is working on them a more dangerous job than changing a lightbulb, and how in the heck do computers do what they do? Stay tuned for those answers and more. [hide full abstract] Member Price: $2.79 Nonmember Price: $3.49 Grade Level: Elementary School, Middle School

More about Charging Things By: William C. Robertson, Ph.D. A chapter from Electricity and Magnetism: Stop Faking it! Finally Understanding Science So You Can Teach It In the first chapter, you charged things up with excess electrons and saw what could happen as a result. Now we're going to get an idea of how to measure how much charge something has, figure out whether an object is positively or negatively charged,...  [view full summary] In the first chapter, you charged things up with excess electrons and saw what could happen as a result. Now we're going to get an idea of how to measure how much charge something has, figure out whether an object is positively or negatively charged, and make up a new concept called the electric field.
