Lesson⭐ 30 XP🌋 Rock RealmThe Water Cycle: Condensation and Precipitation (Part 3)
Earth Systems.
🎯 Your mission
Understand the idea. Then look for it everywhere.
⚡ 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
Weathering breaks rocks into smaller pieces through physical processes (like freezing water expanding in cracks) and chemical processes (like acid rain dissolving limestone).
Key Words
- tectonic plates
- erosion
- weathering
Steps
Look at the vocabulary words and write a definition for each in your own words.
Create a model of the water cycle in a bowl: place warm water in a bowl, cover with plastic wrap, put ice on top, and observe condensation and precipitation.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.

Where you see this in real life
Today's weather, tomorrow's beach, next century's coastline — all this.
Stretch Challenge
Try this in real life this week.
Look at the sky for 5 minutes and try to predict tomorrow's weather.
For the dinner table
“What's the slowest change you can think of?”
