  1. Chapter 1A Goal of Science- to understand the world around us -Science is distinguished from non-science by the scientific method scientific method- systematic approach to problem solving Steps to the Scientific Method • Identify problem/ Propose a question -usually done by making an observation

  2. Gather Information -find out as much as you can about your topic -use resources such as internet, magazines, books, videos, newspapers, interviews *Do Your Research!! -Use your gathered info to: • Form a hypothesis -an educated guess or proposed explanation for what is observed

  3. Design and perform an experiment to test hypothesis -experiment must allow you to prove or disprove your hypothesis -for results to be accepted, the experiment must produce the same results over and over again control- is not changed in an experiment -can only test one variable at a time

  4. independent/manipulated variable- what is changed on purpose dependent/responding variable- what happens in response to the manipulated variable being changed

  5. Analyze results from experiment -must keep careful records of observations made and data collected throughout the experiment -can use graphs, charts, tables to organize data • Prove/Disprove Hypothesis- Conclusion -use your data/results to accept or refute/disprove your original hypothesis

  6. What if hypothesis is not accepted? theory- explanation of natural phenomenon that is supported by many experiments scientific law- summarizing statement of observed experimental facts that has been tested many times and is generally accepted as true
