🎯 Your mission

Set it up. Test it. Be amazed.

⚡ The twist

The slowest changes are the biggest ones.

🤯

Mind = Blown

🪨 Every grain of sand on every beach used to be a mountain.

🔮

Make a hypothesis first

Predict: which will erode faster?

What You'll Learn

Precipitation is water that falls from clouds to the ground. It comes in several forms—rain, snow, sleet, and hail—depending on the temperature of the air the water passes through as it falls.

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

Look for patterns in your observations.

Step 4 — Record

Make a graph or chart showing your results.
