My author friend Terry Jennings has a new book out about magnetism that she wants to share with you. Here’s Terry.
Who wants another book on magnetism? Like poles repel and opposites attract and that’s the way it is, right? Kids already know all about it.
So why did I write another book on magnetism? It’s so much more than the dance between the poles! And that’s what I love about writing non-fiction and creative non-fiction. You find out so much cool stuff.
When I wrote Gopher to the Rescue! A Volcano Recovery Story, I never planned to have a gopher as the main character. But those little diggers (8-12” long) helped Mount St. Helens (9600 feet tall before the eruption) recover. They dug up the ash and softened it so that seeds could sprout. They brought up nutritious bacteria from below. What could be cooler than that?
With Sounds of the Savanna, I learned all about prey and predator interactions. I learned that everybody’s gotta eat ‘cause everybody wants to live! That does mean that sometimes another animal has to die, but it’s surprising how unsuccessful predators are. I also heard that predators cooperate. That makes sense, right? Hyenas and lionesses, they cooperate. But what about prey? Zebras, wildebeest and antelopes all eat the same plant. Zebras eat the old, tough stuff—their teeth are made for it. Wildebeest like the next part. Antelopes love the tender new growth but they can’t get to it until the zebras and the wildebeest have grazed. Wildebeest hide within zebra herds because zebra stripes confuse predators. Cool too, right?
So what was cool about Magnetic Magic? We all do know that like poles repel and unlike attract. But did you know that inside a totally unmagnetic copper pipe a magnet can create both a current and a magnetic field? You can also try it with a totally unmagnetic aluminum pipe. Check it out in my website: http://www.terrycjennings.com/Teacher-Guides-and-Activities-Magic.html give it a bit of time to load and click on the You Tube “Is aluminum magnetic?”
But the coolest thing of all, is that the earth’s magnetic pole shifts. It wonders, from the north geographic pole to the south geographic pole and to places in between. Magnetic North changes from year to year and from place to place. So if a treasure map from a hundred years ago gives coordinate directions from a fixed geographic point and we try to find the treasure this year, we won’t be able to, unless we know the magic number. The magnetic declination. It’s a number we add or subtract from the coordinates (depending on whether the declination is east or west that year). With that number, we can find the treasure.
