Whether it's filled with mossy rocks and ferns or sands and cactus, a terrarium is an amazingly fun way to learn more about nature. With a terrarium in your room, something of the outdoors can always be inside.
Terrariums that feature plants (not animals!) lock water inside to keep the soil moist. When the plants transpire, they let out water vapor. When the soil gets warm, it lets out water vapor. All this vapor collects against the top and falls back as rain.
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.
Our rivers, lakes, and beaches are beautiful, but are they safe? Every day, the toxic runoff from parking lots, busy roads and quiet subdivisions makes its way into our streams and oceans. Even the oil burning off from cars on the roads gets washed into the groundwater and streams by way of the storm drain every time it rains.
The more houses we build, the more pollution we will add to our environment. Every time we lay down a new parking lot or piece of roadway, there is an impact on our environment.
Slow, sleepy winter days find many animals curled up in their dens. They sleep warmly through winter, awakening in spring ready to enjoy the renewed Earth. This unusual, deep sleep is called hibernation.
What Is Hibernation?
True hibernation is a very deep sleep. The animal's body temperature drops, its breathing slows, and it is very difficult to awaken. But some animals, such as most bears, do not really hibernate.
One fine morning, the old wooden dam went up in clouds of smoke and broken timber. It was a huge thing—ancient and strong, built to tame the Rappahannock River. Once the power of the water pushing against it had provided electricity for the town. But that was years ago. The dam was falling apart, but so slowly that it was becoming dangerous. So the Army Corps of Engineers blew it up one morning.
Face it. Cartoons and video games are boring. You can only sit in front of the tee-vee for so long before your eyes glaze over. Between the ads for the latest plastic gizmos and excitingly-shaped wads of sugar (a piece of super sweet hard candy shaped like a pacifier? Puh-leese!), you may realize that the stuff between the ads isn't that interesting either.
It's true: most people would do just about anything to get out of having to speak in public, whether it's the standard "everyone in this class will give an oral report" situation or an acceptance speech for some nifty award you've just received. The knees knock, the heart pounds, and the words you've practiced and practiced and practiced fly right out of your mind. You find yourself resorting to reading from the index cards with your eyes down, your voice a droning monotone, and the sweat beading on your forehead. Yuck. Not a good situation. It's painful for you as the presenter and even more painful for your audience to watch. Here's a bit of advice for beginning public speakers.
May is the perfect time to visit a zoo. It's not too hot or crowded, and the animals are at their springtime best. If your kids are begging for pandas, then the National Zoo in Washington is the place to go, but there are some places about an hour's drive from our area where kids can get a different kind of beastly experience.

Milo was bored. So very bored by school, by books, and by toys that when he found a package marked "One Genuine Turnpike Tollbooth" he figured he couldn't possibly get any more bored by looking at it. So he opened it, set it up, climbed into his electric car and sped off for adventures in Dictionopolis, the land of words, and Digitopolis, the land of numbers. Accompanied by the faithful watchdog Tock, he faces the raucous Dischord & Dynne, the Terrible Trivium, and many other odd and wonderful creatures.
