Have you ever been in a place where there were lots of buildings but no trees? New housing developments or parts of a city that have been neglected for a long time may not have the shady spots and fresh air that trees give. As trees breathe, they let out oxygen that humans and animals need to survive. Their roots hold the ground together, making sure the soil doesn't blow away in the wind. When a tree dies naturally in the forest, its wood becomes a home for insects and a cafeteria for the hungry birds who eat those insects. Trees provide so many good things for the Earth.
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.
The best craft store may be right outside your door. This summer, take time in the cool mornings to gather together pieces of nature to work into craft projects in the afternoons. That way you’ll have a remembrance of summer to keep all year long. Rocks can become patterned pictures. Leaves can make delicate prints. Everything in nature can inspire your arts and crafts.
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.
Moonbird, by Phillip Hoose, is the story of an incredible bird, B95. Through his story, we learn about an amazing species of tiny shore bird, the Rufa Red Knot. The size of a robin, this bird has one of the longest distance migrations of any animal — more than 18,000 miles in a round trip. B95 has made that trip 20 times, flying the equivalent of the distance to the moon and halfway back, earning him the nickname Moonbird.
No matter how hard we try to shelter young children from disturbing news, it has the unfortunate tendency to get through, whether from an overheard conversation or even by putting their new found reading skills to use and learning it for themselves. School begins in a couple of days and your child may be expressing more than the usual post-holiday, lack of interest in returning. Or perhaps they’re clingier than usual and you find you’re exhausting your bag of tricks to help them feel safe and reassured. When you are running out of comforting words, the public library has books that can serve as conversation starters and offer new techniques to support you and your child in managing their fear and anxiety.
How does rain happen? Long ago the Ashanti people believed that Anansi, the Spider, brought the rains that would put out fires in the jungle. In old Britain, the legendary Green Man was supposed to have rainmaking powers, and Zeus brought the rains for the ancient Greeks.
Today, we know that when warm, wet air rises into the sky and cools off, its water condenses out of the clouds as rain. Rain and snow can also happen when a batch of warm air meets a batch of cool air. The two kinds of air usually do not mix. The warm air is less dense than the cool air and will slide right over it. As the warm air goes higher, it cools off, and the moisture separates or condenses out of the cooled air and falls as a slow, steady rain.
Mark your calendars! You will definitely want to visit the England Run Branch between February 26 and April 24, 2013. The Central Rappahannock Regional Library system is one of only ten libraries in the country to successfully apply for the grant-funded, museum-quality science exhibit, Discover Earth: A Century of Change!
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.
