How Erosion Moves Earth

🧪Lab Brief #5

Earth Systems.

🎯 Your mission

Run the experiment. Find out what really happens.

⚡ The twist

Weather isn't random — it's just complicated.

🤯

Mind = Blown

🌊 The deepest part of the ocean is deeper than Mount Everest is tall.

🔮

Make a hypothesis first

Before you observe: what shape will it leave?

What You'll Learn

Erosion moves weathered rock and soil from one place to another by water, wind, ice, or gravity. Rivers carve valleys, wind shapes sand dunes, and glaciers grind mountains.

Key Words

Tap a word to see its definition.

Materials Needed

rocks
water
plastic tray

Safety First

Wash your hands thoroughly afterwards and keep the material away from your face.
Mop up spills straight away so nobody slips, and keep liquids away from sockets.

Steps

Step 1 — Read

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

Step 2 — Do

Model erosion: tilt a tray of soil and pour water from a cup at the top. Observe how channels form. Try adding plants or rocks to slow the erosion.

Step 3 — Observe

Observe what happens and describe it in detail.

Step 4 — Record

Record your observations in your science journal with measurements and descriptions.
