Scientific Method

This scientific method guide outlines how to state a problem, form a hypothesis, conduct an experiment with independent and dependent variables, record findings with a data table and graph, and draw conclusions. Using the example of whether a hard-boiled egg will float in salt water, learn about constants, controls, and the importance of replicating experiments for accuracy.

  1. Scientific Method

  2. State the problem in the form of a question that includes the independent and dependent variable Problem/Purpose • (Will a hard boiled egg float in salt water?)

  3. Hypothesis Educated guess to solving the problem that includes the independent and dependent variables. Ifthe amount of salt added to the water increases,then the hard boiled egg will float) If the independent variableincreases or decreases, then the dependent variable will increase or decrease.

  4. independent Variables • Parts of the experiment dependent constant

  5. Independent (I.V.) The scientist (you) change on purpose. (amount of salt)

  6. Dependent (D.V.) The response from the change made to the independent variable. (float or not float) • Results

  7. Constant (C.V.) • The item that does not change at all. It stays the same Same beakers, same amount of water, same type of salt, Same spoon, same classroom. • Control • No variable is applied to the item

  8. Experiment • Design an experiment to test your problem using the three (3) types of variables (test 3 times for accuracy) constant independentdependent no changeamount of saltfloat or not float

  9. Record Findings Data Table Make a data table showing your results Graph Make a graph to visually show your results.

  10. Conclusion • Restate your hypothesis with the results from your experiment • Should be at least 3 paragraphs for formal experiments.
