  1. The Nature of Science Section 1 Science All Around

  2. A) Scientists are like detectives trying to solve mysteries

  3. 1. Scientists gather information and evidence in their search for answers to questions

  4. 2. A hypothesis is an educated guess about a possible solution to a mystery

  5. B. Scientists use a problem-solving procedure called the scientific method; it includes identifying a problem, gathering information, making hypothesis, testing the hypothesis, analyzing the results, and drawing conclusions

  6. C. Science is a process of observing, studying, and thinking about things to gain knowledge to better understand the world

  7. 1. Any attempt to find out how and why things look and behave the way they do is a performance of science

  8. 2. Earth Science is the study of Earth and space

  9. D. Testing, or experimenting, is an important part of science

  10. 1. Variables are the different factors that can change in an experiment

  11. a. An experiment should be designed so that only one variable at a time is tested

  12. b. The variable that changes, the one being tested in an experiment, is the independent variable The test tubes were left at room temperature for a week to see if algae would grow.

  13. c. Constants are variable that do not change The test tubes were left at room temperature for a week to see if algae would grow.

  14. d. A dependent variable is the variable being measured • The test tubes were left at room temperature for a week to see if algae would grow.

  15. 2. A control is a standard to which results can be compared; the same experiment done with the same variables, except it omits the independent variable

  16. 3. For results to be valid or reliable, tests should be repeated several times

  17. 4. Observing and recording data and discoveries are important parts of an experiment

  18. a. Data and observations must be analyzed to draw conclusions

  19. b. Unexpected results may be important and should be recorded as well

  20. E. Technology – use of scientific discoveries for practical purposes such as making pottery or extracting metals from rocks

  21. 1. Technology is transferable meaning it can be applied to new situations

  22. 2. Earth scientists and biologists use information from satellites to gather weather data and track animals
