Earth's Major Biomes

Lab Brief #3

🎯 Your mission

Run the experiment. Find out what really happens.

⚡ The twist

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

What you'll learn

Biomes are large regions with similar climate, plants, and animals. Major biomes include tropical rainforest, desert, grassland, tundra, and temperate forest.

Key words

organism
Any living thing, such as a plant, animal, or tiny microbe.

Make a hypothesis first

Guess: how does the body solve this problem?

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

Get ready

🧰 What you need

water

⚠️ Safety first

Never look directly at the Sun or into a laser, even briefly.
Mop up spills straight away so nobody slips, and keep liquids away from sockets.

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

Design a controlled experiment: grow plants under different light conditions (full sun, partial shade, no light). Water equally and measure growth daily for one week.

Step 3 of 4 · Observe

Watch carefully for any changes and note the time.

Step 4 of 4 · Record

Create a data table to organize your measurements.

Question 1 of 3

What do plants need to make food through photosynthesis?

How sure are you?😐 maybe

Question 2 of 3

What do hibernating animals do?

How sure are you?😐 maybe

Question 3 of 3

🌍 Where you see this in real life: This is why plants grow toward windows and why scabs form.

🏆 Stretch challenge (try it this week): Watch a plant or pet for 5 minutes today and write down what you noticed.

👨‍👩‍👧 For the dinner table: “Tell me something you noticed about your own body today.”
