The scientific method is a structured approach that scientists use to learn about the world around them. This process begins with observing and formulating scientific questions that can be tested through experiments. Key components include defining variables, forming hypotheses, conducting fair tests, collecting data, and analyzing results. Understanding this method equips individuals with the tools to conduct research, draw conclusions, and even accept failures as learning opportunities. Embrace curiosity and enhance your critical thinking skills through this systematic approach!

  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.
