  1. Chapter 1 Finding Out

  2. Science involves more than the collecting of facts and sorting things into categories. • The real business is solving problems. * some everyday applications * some more abstract

  3. A PROBLEM is a situation in which something appears to be missing. • An EXERCISE is when the steps required to find the solution are obvious.

  4. Simply observing a problem will not help you find the solution. * you must look for clues

  5. How to Solve a Problem. 1.) Look for a pattern. 2.) Clearly identify the problem. 3.) Follow logical steps to the solution.

  6. Problem Solving Strategies 1.) Brain Storming 2.) Trial & Error 3.) Eliminate Possibilities 4.) Make a Model 5.) Concept Mapping (Webbing) 6.) Breaking the problem down 7.) Critical Thinking

  7. Critical Thinking • A process that uses certain skills to solve a problem. * “Flex Your Brain”

  8. The “Flex Your Brain” is an activity that will help you to think about, and examine how you think. * It is a series of steps to keep your thinking on track. * Keeps you organized and structured.

  9. Observation • Using your senses to gather information. * sight * sound * touch * taste * smell

  10. Good observations lead to testable predictions.

  11. Hypothesis • A testable prediction to a problem. * an “Educated Guess” * usually comes in the form of an “IF” and “THEN” statement

  12. If your hypothesis is unsupported (wrong), another one can be proposed and tested. * science advances by trial and error * it is easier to prove something wrong than right

  13. Scientists are trained to question everything and always to look for other possible explanations.

  14. Theory • An explanation (answer) based on many observations supported by experimental results (tests). * the most logical explanation

  15. Theories may be revised or discarded and replaced with another theory as evidence requires one.

  16. Scientific Law • A rule of nature that is generally accepted as true. * theories can serve as explanations of laws

  17. SCIENCE by nature is LAZY! • Shortest route to the answer. • Maximum output for minimum input.

  18. SCIENCE is limited by TECHNOLOGY! • Everything we have learned, everything we have and everything we will discover, will be based on the technology we have available.
