The Water Cycle
A huge puddle covers the four-square court at Mateo's school, and by lunch it's gone. Students follow the water: evaporation, clouds, four kinds of precipitation, runoff and groundwater, where Earth's water is, and a water-cycle-in-a-bag experiment they can do in class.
What is inside
- Where did the puddle go?
- Up into the air
- Clouds and rain
- Around and around
- Earth's water
- Try it: a water cycle in a bag
- Check your understanding (11-question graded quiz, 70% to pass, 3 attempts)
- Going further (two short videos)
The bag experiment needs a zip-top bag, a marker, water, tape, and a sunny window. Instructions and a checklist are in the course.
The last lesson has two YouTube videos, so that lesson needs internet access. Everything else works offline.
