Read the passage below together. Switch readers for each paragraph. After reading, discuss the "Main Idea" (the big point) before answering the questions.
Paragraph 1: Beavers are often called "nature's engineers" because they are one of the only animals that can change an entire environment to suit their needs. These large rodents live in North America and spend most of their time in and around the water. While they may look clumsy on land, their webbed feet and paddle-shaped tails make them excellent swimmers. Their most famous skill, however, is their ability to build massive structures that transform small streams into deep, calm ponds.
Paragraph 2: To build a dam, beavers start by gnawing down trees with their incredibly strong, orange-colored front teeth. They use branches, logs, and stones to create a thick wall across a moving stream. To make the wall waterproof, they scoop up mud from the bottom of the stream and use their paws to plaster it into the cracks. This structure blocks the flow of water, causing it to pool up behind the dam. This creates a safe, deep pond where beavers can build their homes, called lodges, away from predators like wolves and bears.
Paragraph 3: Beaver dams do more than just help the beavers; they help the whole forest. When a dam creates a new pond, it also creates a wetland. These wetlands act like giant sponges that soak up water during heavy rains, which prevents flooding downstream. Many other animals, such as ducks, frogs, and fish, move into these new ponds to find food and shelter. By building their dams, beavers create a thriving home for hundreds of different species in the wild.
1. What is the main idea of the entire passage?
Beavers have orange teeth and webbed feet that help them swim.
Beavers use mud and sticks to build homes called lodges.
Beavers are amazing builders that change the environment for themselves and others.
Beavers live in North America and try to hide from predators like bears.
2. Which sentence best describes the main idea of Paragraph 2?
Beavers have very strong front teeth that never stop growing.
Beavers follow a specific process to build dams that create safe ponds.
Mud is used to plaster cracks in the walls of the beaver's dam.
Wolves and bears are the main predators that beavers must avoid.
3. According to Paragraph 3, how do beaver dams support the whole forest?
They provide a place for beavers to store their extra food for winter.
They help beavers swim faster when they are escaping from predators.
They create wetlands that prevent flooding and provide homes for other animals.
They make the water in the stream move faster so it stays clean.
4. Which detail from the text supports the idea that beavers are "nature's engineers"?
Beavers live primarily in North America near bodies of water.
Beavers have paddle-shaped tails that help them swim in deep ponds.
Beavers can transform moving streams into calm, deep ponds.
Beavers are large rodents that can be clumsy when they are on land.
5. Why do beavers plaster mud into the cracks of their dams?
To make the structure waterproof and block the flow of water.
To hide the branches from predators that might try to eat them.
To create a soft place for their babies to sleep inside the dam.
To sharpen their front teeth while they work on the structure.
