How Beavers Build Their Homes
According to the passage, where do beavers usually live?
Near rivers, ponds, and streams
Which teeth do beavers use to cut down small trees and branches?
Strong front teeth.
What does a dam create by slowing down water?
What two materials make up a beaver lodge, according to the passage?
Sticks and mud.
What part of the beaver helps it steer as it swims?
Wide, flat tails.
What three materials does the passage say beavers use to build a dam?
Sticks, stones, and mud
After cutting down wood, what do beavers do with it before adding it to the dam?
Drag the wood to the water and add it to the dam.
How does the finished dam help beavers, according to the passage?
It helps keep the water deep around their home.
Where are rooms in a beaver lodge located?
Above the water.
What feature of beaver feet helps them push through the water?
Webbed back feet.
Why do beavers slow the flow of water with a dam?
To slow the flow of water and create a pond; this keeps water deep around their home.
The passage explains beavers pack mud and leaves into the spaces. Why is this step important for the dam's function? Support your answer with text evidence.
Packing mud and leaves fills gaps so the dam holds water and stays solid.
The passage says their building "can change the area around them by making ponds where other plants and animals may live." What is the one possible effect on other animals? Use the text to explain.
It can create habitat for other plants and animals' the passage explicitly says other plants and animals may live there.
Why do beavers have an underwater entrance to their lodge? Use the passage to explain two reasons.
The underwater entrance helps beavers swim in and out and makes it harder for some animals to enter.
They slap their tail on the water; the loud splash warns other beavers.
How do beavers make it harder for some animals to enter their lodge? Give two details from the text.
Underwater entrance makes it harder for some animals to enter; rooms are above the water inside the lodge.
Explain how building a dam is both a tool-use behavior and a survival strategy for beavers, using details from the passage.
They cut, carry, and arrange materials to change water flow and create sager living conditions - a survival strategy supported by the passage.
Based on the passage, why might a pond created by a beaver dam be important for the beaver's lodge?
A pond keeps water deep, which helps maintain the lodge's underwater entrance and rooms about water.
The passage says a lodge "may look like a pile of branches, but inside there are rooms above the water. "What does this detail tell you about appearances versus reality? Answer using the text.
It shows something may look simple outside but be complex inside - the text contrasts appearance and reality.
Explain how the beaver's physical adaptations and behaviors work together to help it live in the water. Use at least three details from the passage.
Adaptations: wide flat tail steers, webbed feet push them through water, tail slap warns others; building dams and lodges complement these features.
The passage says beavers "keep fixing their dams when water washes pieces away." What can you infer about beaver behavior and their relationship to their environment? Use evidence from the passage.
Beavers repair dams when pieces wash away.; inference: beavers are persistent builders who actively maintain and change their environment.
The passage calls beavers "known for building dams and lodges." Based on details in the passage, how does this buiding change the area around them? Cite specifics.
Building dams creates ponds and changes areas so other plants and animals may live there; the passage states this.
Use text details to describe how beavers respond when water washes pieces away from their dam and what this shows about their role in shaping habitats.
Beavers keep fixing dams when washed away, showing ongoing maintenance and habitat engineering.
Using details from the passage, explain how the construction of a lodge helps protect beavers from danger and how that ties to their behaviors.
The lodge's design (rooms above water, underwater entrance) offers safety from predators and allows easy access for beavers.
The passage lists several physical features and behaviors (tail, webbed feet, slapping tail). Draw a conclusion about why these features are important for both individual survival and for the beaver family or group, citing explicit details from the text.
These features help individual beavers swim, maneuver, and warn others; with building behavior they support family survival and habitat creation.
