Materials:

2 Plastic Bottles
Potting Soil & Rocks
Small Plant
Tapes
Water

  1.  Cut the tops off the two bottles.
  2.  Fill one with rocks and then the soil.  Add the plant.
  3.  Add water to the soil
  4.  Place the other bottle on top of the first and use the tape to connect them, creating a seal.
  5.  Observe, over time, as water vapor condenses and collects on the inside of the top bottle

Questions to consider:

  • How did the water get to the top of the bottle?
  • How long did it take?
  • How can we observe this in nature?
