Living Things Change the Place They Live

Lab Brief #6

🎯 Your mission

Master the concept. Use it tomorrow.

⚡ The twist

Nature loves to surprise the careful watcher.

What you'll learn

A beaver dams a stream and makes a pond. Worms tunnel and let air into soil. Tree roots crack rock. Living things do not just fit their habitat — they change it, sometimes a great deal.

Key words

burrow
A hole an animal digs in the ground to live in.
dam
A wall built across a stream that holds water back into a pond.

Make a hypothesis first

Before you start: write down what you think will happen, and why.

Say your guess out loud — then find out if you were right.

Step 1 of 4 · Read

Think about what you just learned: say what "burrow" and "dam" mean in your own words before you start.

Step 2 of 4 · Do

Nice work!

You got 0 of 2 right.
