Cover to Mountains of the Heart: A Natural History of the Appalachians

Nature programs on TV can only go into so much detail about the fascinating history that underlies our beautiful world. After all, there are commercial breaks to consider and trying to produce a show for the most casual channel surfer. So viewers come away with an idea of what a place looks like—and maybe a few facts about it—but for the truly curious, there is a dearth of content.

Mountains of the Heart: A Natural History of the Appalachians, by Scott Weidensaul, has been a go-to classic for around 20 years. Written in a casual and fascinating yet scientifically accurate way, the narrative draws in readers who do not want to crack academic tomes on the subject but who do wish to learn more about the region’s alpine tundra and the still-living remnants of mighty chestnut trees.

Pet rocks are back! Or, maybe they never went away. They've got a really, really long lifespan, after all. These throwbacks (careful where you aim them, though!) to the 1970s can be a lot of fun to collect or just use for interesting paperweights.

It's time to break out the pans of soapy water for a wet and wonderful outside Bubble Party. You can buy bubble solution, but it's cheaper to make your own. Take a cup of water, 2 tablespoons of light corn syrup, 4 tablespoons of dishwashing liquid, and mix them together gently. Do not mix it so much that it foams.

Pour it into a shallow pan, or seal it tightly to use later. You can either use store-bought bubble wands, or you can twist wire or pipe cleaners into shapes to catch the film. Make sure you keep your hands nice and wet to keep the bubbles from popping, and don't let the little ones drink the bubble mix.

Rocks come in all shapes and sizes, but what kind are they? You can’t ask them, but sometimes, if you know how to listen, they’ll tell you anyway.

The shape and size of a rock doesn’t tell you much about what it’s made of.
Big rocks break into smaller rocks all the time. But there are other things to look for that can give you their I.D.

Camping, fishing, hiking, history, grand vistas, and horseback riding--there are so many possibilities in our national parks.

What do the Earth, electric motors, and your computer all have in common?
These things are all influenced by magnets.

The Earth has a liquid metal core that acts like a bar magnet. It gets its magnetism from being near electrical currents beneath the surface. Because the Earth is not perfectly shaped, every so often the direction of the field will change. Scientists have found evidence that this has occurred at least 171 times over the past 71 million years. How do they know that? Magnets!
