Summary

Sid wonders what happens to water after it goes down the drain or soaks into the ground. At the Science Center, the class tests different surfaces — sand, soil, and pavement — to see which absorb water and which don't, building an understanding of how Earth handles water.

Discussion questions

Discussion

Water disappears from a puddle — but where does it actually go?

  1. What happened when Sid poured water on soil? On pavement? Why were they different?
  2. Is the water really gone when it soaks into the ground? Where do you think it goes next?
  3. Why might it matter that some surfaces absorb water and some don't? (Think about floods and plants.)

Quick work-a-long

Vocabulary: absorb, drain, surface, soil, water, observe.

Try it: Pour a small cup of water onto three surfaces (a sponge, a plastic lid, and a paper towel). Watch what happens. Which absorbs the most? Which is most like pavement?
