Introduction

This sheet has instructions for building a model water cycle and a place to record your observations for the activity.


Materials

  • A large metal or plastic bowl
  • A pitcher or bucket
  • A sheet of clear plastic wrap
  • A dry ceramic mug (like a coffee mug)
  • A long piece of string or large rubber band
  • Water

 

Directions

  1. Put the bowl in a sunny place outside, on a windowsill, or on a table under a window.
  2. Using the pitcher or bucket, pour water into the bowl until it is about ¼ full.
  3. Place the mug in the center of the bowl. Be careful not to splash any water into it.
  4. Cover the top of the bowl tightly with the plastic wrap.
  5. Tie the string/or rubber band around the bowl to hold the plastic wrap in place.
  6. Observe the bowl as it is now and write down your observations below.
  7. Let the bowl sit in the sun for a couple of hours and then observe it again to see what has happened.
