Hot Roads Cool Off Some streets in Los Angeles, California, are getting a cool makeov er. The city is painting some streets with special light-gray paint. Why? They hope it will help keep the city a bit cooler. Dark surfaces absorb lots of sunlight. But sunlight bounces off light er colors. That’s why you get hott er standing in the sun in a black t-shirt than in a white one. Cities are full of streets paved with black asphalt. Black str eets get extra hot in the summer. But what if they could bounce the heat off instead? In tests, painting a parking lot light gray kept it 10° F (5.5° C) cooler. Now the city is t esting the paint on roads. If it works, it could help prevent heat waves. BOATS MAKE…

how rivers run

Source Snow melts in the mountains. Rain falls on land. Water seeps through soil and rock. Streams trickle downhill, following the lowest path. All that water collects in rivers. Tributaries Small streams join up to form bigger streams, which merge into rivers. A smaller stream that flows into a bigger one is called a tributary. Groundwater Rain seeps through soil and rock into underground waterways. Some flows out in springs. Some feeds rivers from underneath. Rapids and Riffles Where fast-moving water flows over rocky ground, it forms wavy riffles and foamy whitewater. Beaver Dam Beavers build twiggy dams across streams to make small ponds. Beaver dams don’t block the water entirely. The ponds make homes for fish, amphibians, and birds. Meander Sometimes a river’s path twists and turns. These turns are called meanders.

busy beavers

Beavers are the largest rodents in North America. They have sharp orange teeth that can gnaw through trees. And like humans, they build dams. A Perfect Pond When it’s time to build a new dam, beavers look for a nice shallow stream with plenty of tasty trees nearby. Beavers gnaw down trees to make their dams. They also eat leaves and the sugary layer under tree bark. But not all trees taste good. Aspen, cottonwood, maple, and willow trees are their favorites. This beaver family finally finds the perfect place—a shallow stream in an aspen grove. The water is moving slowly. And what luck! A tree has fallen across the stream. They’ll start building their dam right there. Mom, Dad, and the kits all help. They work at night to avoid predators like wolves…

our creek

Where Does the Water Come From? Where Is It Going? The water in our creek comes from rain and snow falling on land for miles around. Standing Stone Creek is one of many small streams that all flow into the Susquehanna River. Eventually, all that water empties into the Atlantic Ocean. Standing Stone Creek may look small, but it’s important. It carries water to forests, towns, and farms. Lots of animals, birds, and insects live in the stream and along the banks. It’s a fun place for people to boat and fish. And we get our drinking water from it! So it’s important to keep it clean and healthy. Today we’re going to get to know it a little better. Along the Banks First stop is the woods beside the river. Healthy streams need healthy…

building hoover dam

I carry water from the mountains across dry deserts and through deep canyons, all the way to the Pacific Ocean. I am so mighty, I carved the Grand Canyon! Yep, that was me! Took me a really long time. But it looks fantastic! I’m so strong and fast, I wash away a lot of soil and rock and silt. So my water’s kind of muddy. Some people say I’m “too thick to drink, to thin to plow.” In the old days I dumped all that silt on California, where it made pretty good soil. Sometimes in spring, I overflow with water from melting snow. I have to spread out a little. You call that a flood. But I don’t do that so much anymore. Why? I’ve been chained up! Tamed! Domesticated! Put to…
