The Scientific Method 2011 acloutier copyright 2011

  1. 1. The Scientific Method by A.Cloutier 2011 Sandwich High School copyright The process of finding answers to questions we have concerning matter in our world
  2. 2. The Scientific Method discussed here deals with seven steps <ul><li>the Scientific Method </li></ul><ul><li>a process of thinking and making observations </li></ul><ul><li>of our world </li></ul>
  3. 3. Is there only one scientific method ? <ul><li>No ! several versions exist and have varying number of steps </li></ul><ul><li>however…all begin with a question to be answered based on observations of the world around us </li></ul><ul><li>the scientific method provides an organized method for conducting an experiment and analyzing it </li></ul>
  4. 4. Steps we explore … <ul><li>1. formulate a question </li></ul><ul><li>2. research the question </li></ul><ul><li>3. form a hypothesis </li></ul><ul><li>4. conduct an experiment </li></ul><ul><li>5. analyze data </li></ul><ul><li>6. draw conclusions </li></ul><ul><li>7. communicate results </li></ul>
  5. 5. Do scientist really use this method ? <ul><li>Yes ! Many use the scientific method daily, but, not necessarily all the steps are needed = much time is collecting data and analyzing it </li></ul>
  6. 6. Surprisingly business’ use a version of the scientific method <ul><li>Businesses in the USA and other countries have adapted the steps in solving a problem to help employees and managers diagnose a problem and test ideas to solve it </li></ul>
  7. 7. Formulating a question <ul><li>What needs to be solved ? </li></ul><ul><li>What do you want to know or explain ? </li></ul><ul><li>Use observations you have made and write a question down that addresses the problem or topic to investigate </li></ul>
  8. 8. Research a question <ul><li>Research lets us know if others have already done an experiment and have data to share </li></ul><ul><li>Sometimes expanding the concept with research have us evaluate and change a variable </li></ul><ul><li>Ask “why should I explore this concept ?” </li></ul>
  9. 9. Hypothesis <ul><li>what do you expect to happen ? </li></ul><ul><li>predict the outcome of the experiment </li></ul><ul><li>the “if….and then….” statement </li></ul><ul><li>“ if” being the observations of the problem </li></ul><ul><li>“ then” is the hoped for results </li></ul>
  10. 10. Conduct the experiment <ul><li>Design a procedure to test the hypothesis see if the prediction happen </li></ul><ul><li>Record all data and observations in a neat and organized way (graphs or tables) </li></ul>
  11. 11. What is the “control” in an experiment ? <ul><li>whatever is happening in the natural world , without a specified influence, is the “control” </li></ul><ul><li>is also known as “normal”, the control is what would be happening in life, or the regular physical world, without a scientist changing anything in the process </li></ul>
  12. 12. The Variable is used in designing an experiment when selecting a different outcome <ul><li>we predicted in the results of the experiment in the “hypothesized” statement </li></ul><ul><li>“ if potatoes are given more potassium in the soil, then the size of the tuber (potato) will be greater at harvest.” </li></ul>Got potatoes ?
  13. 13. Analyze the data and observations <ul><li>Is the data reliable </li></ul><ul><li>Does it make sense </li></ul><ul><li>Produce charts, graphs, or tables to organize it. </li></ul>
  14. 14. Draw conclusions <ul><li>does the data and observation support the hypothesis </li></ul><ul><li>might it need to be changed </li></ul><ul><li>does the experiments procedure need to be re written </li></ul>
  15. 15. Communicate results <ul><li>let others know what you have learned </li></ul><ul><li>make a formal LAB REPORT </li></ul><ul><li>could this lead to new hypothesis or questions to learn more about </li></ul><ul><li>if so…. </li></ul><ul><li>you are back at step one ! </li></ul>
