When scientists are studying a problem they make observations and then develop a hypothesis to explain their observations. What exactly is a hypothesis? Many people refer to a hypothesis as an educated guess that is based on information that a scientist has already learned. In other words, it is not just a wild guess!

See if you can develop a hypothesis about water use based on what you have observed so far.

Observations
Think about what you have learned about water use so far. Think about how much water you, your family, and your classmates use on a daily basis. How do you think your class average daily water use would compare to the amount of water used by people living in other parts of the world?

Develop a Hypothesis
Brainstorm several hypotheses and then pick one to investigate. Think about these questions to help you develop a hypothesis:

  • How do you think the average amount of water you use in one day compares to what other Americans use?
  • Do you think people in other parts of the world use more or less water than Americans? Why?
  • What factors contribute to water usage?
Examples of hypotheses might be:
  • People in drier climates use more water than people in rainier climates.
  • Americans use more water than people in Europe.
  • Water usage depends on geographical location.
  • People who live near oceans use less water than people who do not.
