Question – ask a question and research your topic ◦ Questions must be “open ended” ◦ Open ended questions cannot be answered with a simple “yes” or “no”
Hypothesis – what is your best guess Procedure – write very specific directions for your experiment ◦ Your procedure should be clear enough for any other scientist to follow and get the same results as you did
Experiment – observe closely and record your data Data Analysis – organize and evaluate your data ◦ Make sure that your method is appropriate to the experiment. Data Analysis is not always conducted the same way.
Conclusion – What did you find? Is your hypothesis correct? ◦ Based on your conclusion, you should either repeat the test multiple times for validity OR revisit your hypothesis Abstract – Summarize your experiment
Independent Variable – The variable that is changed by the scientist ◦ To insure a fair and VALID test, a reliable experiment should have only ONE independent variable
Dependent Variable – Caused by the independent variable. ◦ If independent variable, then dependent variable. ◦ If I add fertilizer to my crops, then my crops will grow taller and more abundant. ◦ If I add red food coloring to my cupcake mix, then my batter will turn a shade of red.
Control – a group where the factor being tested is NOT applied so that it may serve as a standard of comparison against the group where the factor IS applied. ◦ In the farming example, the control would be crops that did not receive fertilizer. ◦ In the baking example, the control would be the batter that did not receive red food coloring.
Constant – A condition or factor that is kept the same throughout the experiment ◦ In the farming example, some constants would include soil, sunlight, water in order for my experiment to be VALID. ◦ In the baking example, the constant would be the same cake mix/cookie mix.
