The Scientific Method

Careful scientists use the scientific method every day!

The world is full of questions. What causes volcanoes to form? Why does it rain? The scientific method was developed to provide an unbiased way of finding the best possible answer to a question.

The scientific method was developed so scientists could test possible explanations to questions, and allow others to verify the results. There are five general steps when applying the scientific method:

  1. Make observations
  2. Ask a question based on observations
  3. Form several hypotheses
  4. Test the hypotheses
  5. Make a conclusion

Burrowing owls are unique among birds because they nest underground in existing ground squirrel, coyote, and badger burrows. They are also commonly associated with humans and will frequently nest in burrows along irrigation ditches, canals, and even in people’s yards.
