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