  1. Scientific Method Notes

  2. Scientific Method • The way scientists learn and study about the world around them

  3. Observe and Question • Observe- Make notice of things in the world around you • Scientific Question- A question that is testable through an experiment

  4. How many pennies can a bessbeettle pull? • Why do leaves change colors? • What causes cancer? • How could I design a more efficient light bulb that uses less energy and saves money? • What impact does human use of pesticides have on the environment?

  5. Is this Testable? • A good scientific question is testable • Not Testable • Ghosts? • Religion? • Feelings or Opinions?

  6. Variables • The parts of the exp. that ARE changing! • Independent Variable- This is what you are testing or changing in the experiment • There should only be 1 in an experiment • Dependent Variable- This will change because of the independent variable. This is the data/what you measure in an experiment

  7. Constants • Constants are things that stay the same between each trail/test. This should be EVERYTHING except for the in depended variable.

  8. Fair Test • There is only 1 independent variable • Constants- everything else in an experiment that should be kept the same • This way you know that the dependent variable changed because of what you were testing and not because of an outside factor

  9. Hypothesis • Define- An educated guess for why what you observed is happening • Should be an IF…. THEN…. statement • Example- If I eat more cookies then I will run faster

  10. Control Group • The group that isused as a comparison to the group being tested

  11. Procedure • Step by step description of how you will do the experiment • What should be included in the procedure?

  12. Data Table • A table including the information that you gather

  13. Present Data • Chart- arranges information from the experiment visually, such as in a table

  14. Analysis Data • How you explain your data • Often in the form of a graph • Looking for patterns

  15. What if the answer is not what we are looking for? • THATS OKAY TOO! • It’s just as important to know what doesn’t work as it is to know what does • Thomas Edison- "I have not failed 1,000 times. I have successfully discovered 1,000 ways to NOT make a light bulb."

  16. Conclusion • Was your hypothesis supported? • Should be written as: My hypothesis was/was not supported because … (this data showed)

  17. Error Analysis • Things in your experiment that you may or may not have been able to control that affected your experiment.
