The Scientific Method The Scientific Method Presentation Transcript

  • The Scientific Method
    • To start click here
  • Click One of the Following To Start Your Tour
    • Testable Question
    • Writing A Hypothesis
    • Gathering Materials
    • Writing A Procedure
    • Conducting The Investigation
    • Recording Data
    • Drawing Conclusions and Sharing Results
    • Quiz and Activity (Do Not Click Until All Others Have Been Studied)
  • The Testable Question (Problem)
    • Before you start an experiment you must have a reason to do it.
    • You need to have a question that can be answered through an investigation
    • This is called a “Testable Question.”
    Click For More ->
  • Examples of the Testable Question
    • Does the amount of sunlight a plant gets affect how it grows?
    • Does the size of the hole in the bottom of a sinking water clock affect how fast it sinks?
    • Does caffeine affect reaction time in middle school students?
    • Which disinfectant works the best on household germs?
    Next Slide ->
  • These Are Not Testable Questions
    • Is Jerry Rice the best receiver of all time?
    • Does water smell good?
    • Is the cafeteria food good?
    • Will the school be open tomorrow?
    • You cannot answer these questions with an experiment. Opinion questions are not testable.
    Menu
  • Gathering Materials
    • In order to do an experiment, you must make a list of the equipment you will use.
    • This list is written above your procedure.
    • It allows other people to do your experiment without having to ask you what they need.
    Home
  • Writing a Hypothesis
    • A hypothesis is an “educated guess” about the out come of your experiment.
    • In order to make this guess, you must rely on your background knowledge and the research which you conducted before you began planning the experiment.
    Click Here for More!
  • Hypothesis and Research
    • It is VERY important that you conduct research before you make your hypothesis. This research will give you the information you need to make a hypothesis that is scientific and accurate.
  • A Well Written Hypothesis
    • A well written hypothesis consists of an “if” statement and a “then” statement.
    • The “if” statement contains information on what your are testing, and the “then” statement reflects your beliefs of the outcome of the experiment.
    Click Here For Some Examples!!!
  • Examples
    • “ If we change the size of a hole in the bottom of a funnel, then the funnel will sink at a faster rate”
    • “ If caffeine is increased in someone’s body, then their reaction time will be quicker”
    Back Home
  • Writing A Procedure
    • A procedure is a list of steps that a scientist takes to complete the experiment.
    • This is a very detailed list that is numbered in 1,2,3..... order. It is not a paragraph! It may include drawings.
    • You know you have written a good procedure when someone can read it and do the experiment exactly like you did.
    Click Here For An Example!
  • Water Clock Procedure
    • 1. Fill a clear, 4 liter bucket to 1 inch from the top
    • 2. Place funnel on the top of the water with the hole facing down
    • 3. Let funnel sink and record the time it takes to hit the bottom
    • 4. Record this time in a data table
    • 5. Take the funnel out of the water and place one, 3/4 inch brass washer inside the funnel.
    • 6. Repeat steps 2 through 4.
    • 7. Repeat step 5 by adding two, 3/4 inch brass washers inside the funnel.
    • 8. Repeat steps 2 through 4
    • 9. Repeat step 5 by adding three, 3/4 inch brass washers inside the funnel.
    • 10. Using your data table, make a line graph representing the sinking times of all three funnels.
    Home
  • Conducting The Investigation
    • It is now time to start testing your hypothesis!
    • This is the step that we all want to jump right into. However, it is very important that we complete the previous steps first.
    • Safety is always an issue here. Be sure to follow all lab safety procedures while conducting the investigation
    More ->
  • Investigation
    • If you have written a detailed procedure, your investigation should go smoothly.
    • Simply follow the steps in your procedure!!
    • Be sure to clean up your materials when you have finished!
    Home
  • Recording Data
    • All measurements in an investigation need to be recorded in a data table.
    • The table must have a title (related to what you are measuring), and appropriate labels for the rows and columns.
    Sinking Time For Funnels (seconds) Trial Number 1 2 3 Avg. Number Of Washers 0 1 2 3 110 90 80 93.3 36 31 40 35 12 17 17 15 12 10 14 12 Click To See The Graph
  • Graphing Your Data Table
    • In order to understand and interpret you data, you need to make a graph.
    • A graph lets you see trends in the data and it also helps you look at the data in a way that is easy to understand.
    • When graphing, use the “T.A.I.L.S.” method. This will insure that all of your labels and increments are correct!
    • Remembe r your labels!!
    Home
  • Drawing Conclusions
    • The final piece of the scientific method is drawing conclusions.
    • In this step we analyze our data and graphs and decide if our hypothesis was correct or incorrect! We always restate our hypothesis in our conclusion.
    • We discuss any trends we see and we attempt to explain why our hypothesis was correct or incorrect.
    • This is always in paragraph form!
    Conclusion In conclusion, I can say that my hypothesis (if we add more washers to the funnel, then it will sink faster) was correct. The funnel did sink faster when I added more washers. My graph shows a decrease in sinking time so I have proved that this is true. Sharing Conclusions
  • Sharing Conclusions
    • To make our experiment complete we must share our findings with other people.
    • This can be through discussion or a lab report printed for a magazine. Scientists love to read about other’s experiments!
