This What is the Water Cycle? Activity A lesson plan also includes:

Pros

  • Student journal pages provided for recording answers and observations
Cons

  • Requires a small milk carton for each team; you will need to have students start bringing some in before the day of the lesson, or use paper cups that can be just as easily peeled off of the frozen blocks
  • The activity is only loosely related to the title of the lesson; it might be more approprately called "Properties of Water"
