Bottles for Very Old Babies Thousands of years ago, some people in Europe made strange clay cups with little spouts. Some of the cups were shaped like animals. Archaeologists who dug up these ancient cups didn’t know what they were. But new research hints that they were baby bottles. Scientists studied several spouted cups between 2,500 and 3,200 years old. They did chemical tests on the clay to see what the cups might have held. In two cups, they found traces of fat that matched the milk of cows, sheep, or goats. Another cup had traces of milk from pigs or humans. That means long ago, people may have used these cups to feed babies milk. And that would have meant healthier babies—anyone could feed them, when Mom was off hunting. THE THREE…

little questions in the big woods

How do trees know when it’s spring? A It gets warmer. B The squirrels tell them. C The days get longer. Trees can sense temperature and light. Changes in the weather trigger changes in the trees. Trees slow down for winter when nights get longer. They wake up again when daylight lasts longer than night. They are not fooled by shade or street lights; sunlight is a different “flavor” of light to them. Trees also know it’s time to grow new leaves when they feel several weeks of warm weather after a long cold spell. A and C Why is that tree eating a sign? A To get extra iron. B The sign got in the way. C It’s controlled by a sign-eating fungus. Trees never stop growing. They grow taller from the top and wider by adding new…

can trees talk?

If someone asked you if trees could talk to each other, you might say no. But scientists are listening to trees in whole new ways. Now they think the answer to that question is yes. Hidden Helpers Trees don’t whisper to each other on the wind. They talk to each other with the help of fungi (mushrooms) deep underground. Scientists sometimes call this the “wood wide web,” because it’s a bit like an internet for trees. How does it work? Imagine following a tree root deep underground. You notice that the roots are covered in fine white fuzz that stretches out into the soil, like a cottony web. Did spiders do this? No, the white threads are hyphae, the underground part of mushrooms. The hyphae’s job is to soak up minerals and water from…

old oak’s advice for young acorns

How can I grow as big as you? Eat up your carbon dioxide, and try to fall in good soil. If you don’t want to tip over, get your roots in nice and deep. And remember, a tree’s best friends are really, really small. Bacteria and fungi may not look pretty, but be nice to ’em and they’ll give you tons of tasty nitrogen. Do squirrels tickle? Them squirrels is tickly. But don’t shake ’em off. You need ’em to bury your acorns. When will I be tall? You just work on gettin’ your tap root down first. Then you’ll shoot right up—if a deer don’t eat you. Whack its nose if it tries. We oaks can live 1,000 years and never stop growing, so take your time! Up from the top and bigger around…

porcupette explores the night

The full moon is rising over rocky mountain peaks. It shines down into a canyon. Under the roots of an old pine tree, there is scuffling and snuffling. A young porcupine, called a porcupette, comes out of the den where she spent the day resting. Her mother is still asleep in the branches above. Porcupette looks awkward as she slowly waddles on her short, sturdy legs, but she is calm and confident. She is not bothered when a raccoon trundles past her on its way to fish in the nearby stream. She is not afraid to come out at night alone. Right now, Porcupette is hungry. Mother’s milk is good, but porcupines are born with a mouth full of teeth and ready to bite. Porcupette is looking for something to chew on.…

forest layers

Broadleaf Forest Look up! Life in the woods is lived on many levels. At the top, the sunny canopy is open to the wind and weather. Moving down, each level of a forest gets a different amount of light and water. Every level has its own community of birds, animals, insects, and plants. There are also many kinds of forests. In a broadleaf (or deciduous) forest, trees shed their leaves every year. Boreal Forest (Taiga) In cold northern forests, many trees are evergreens. They have needles instead of leaves. Just a few feet under the surface, the soil may stay frozen all year round. During the short summers, the ground is wet and boggy. Lichens high in the treetops drop nutrients that enrich the soil. Animals of the taiga survive the winter by…
