Nature’s Engineers
1 Imagine you are walking through the woods and you hear a loud thump! You look toward a nearby stream and see a furry animal with a flat tail swimming away. You have just spotted a beaver. Beavers are the second-largest rodents in the world. They are famous for their ability to change the land around them. Because they build structures that change the environment, they are often called "nature's engineers."
2 The most famous thing a beaver builds is a dam. A dam is a wall made of sticks, logs, and mud. Beavers build dams across streams and small rivers to block the flow of water. This creates a calm, deep pond behind the dam. Beavers are excellent swimmers, but they are slow on land. By creating a pond, they can swim safely away from predators like wolves or bears.
3 In the middle of their new pond, beavers build their home, called a lodge. A lodge is a dome-shaped house made of the same materials as the dam. It has an underwater entrance. This keeps the beavers safe inside because most other animals cannot swim underwater to get into the house. Inside, the lodge has a dry room where the family sleeps and eats.
4 Beavers have special tools on their bodies to help them work. Their front teeth are very strong and never stop growing. They use these teeth like sharp chisels to chew through thick tree trunks. They also have large, flat tails that act like a rudder to help them steer in the water. If a beaver senses danger, it will slap its tail on the water to warn other beavers.
rudder: a flat piece used for steering a boat
chisels: tools with a sharp edge used for cutting wood

Sample Proficient Response
"Beavers have special body parts and build structures to survive. They have flat tails that help them steer like a rudder. They also use their tails to slap the water to warn others of danger. Their teeth are like chisels to chew wood. Beavers build dams to make deep ponds so they can swim away from bears. They also build lodges with underwater doors to keep their families safe from other animals."
