A visual, informative and hands-on activity that will help describe the amount and distribution of water on Earth.  Students will discover why Earth is considered the “water planet” but that much of its water is not readily available for human use.  Participants will come to understand that much of the water available to humans and wildlife depends largely on how its quality is maintained; therefore it is important to conserve water and take care of it!

Key Messages

  • Earth is considered the "water planet" as approximately 75% of its surface is water
  • Water is found in a variety of locations and forms on Earth
  • All of this water is part of the hydrologic cycle
  • There is a difference between fresh water and salt water
  • Water Available to humans is very limited
  • Water conservation is important!

Ontario Curriculum Connections

Science and Technology:
  • Understanding Earth and Space Systems, Grade 5 (Conservation of energy and Resources)
    • analyze the long-term impacts on society and the environmental of human uses of energy and natural resources, and suggest ways to reduce these impacts (e.g. turning off the faucet while brushing teeth or washing and rinsing dishes conserves water)
    • evaluate the effects of various technologies on energy consumption, and propose ways in which individuals can improve energy conservation
