Surviving Winter by Hibernating

Lab Brief #4

🎯 Your mission

Learn the rule. Then catch nature using it.

⚡ The twist

What the body does in one minute is wilder than any cartoon.

What you'll learn

Hibernation is a deep sleep that helps animals survive winter when food is scarce. During hibernation, an animal's heart rate and breathing slow down to save energy.

Key words

food web
How plants and animals are linked by what they eat.

Make a hypothesis first

Guess: how does the body solve this problem?

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

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Create a detailed food web for a local ecosystem. Include at least 8 organisms and use arrows to show energy flow from producers to top predators.

Step 3 of 4 · Observe

Look for patterns in your observations.

Step 4 of 4 · Record

Make a graph or chart showing your results.

Question 1 of 3

What do hibernating animals do?

How sure are you?😐 maybe

Question 2 of 3

What is the main source of energy for most food chains?

How sure are you?😐 maybe

Question 3 of 3

What happens to energy as it moves up a food chain?

How sure are you?😐 maybe

Mind = blown

🦠 You have more bacterial cells in your body than human cells.

Nice work!

You got 0 of 3 right.
