A scientific question asks about the relationship between the IV and DV of an experiment.
What is the effect of____(IV)____ on ___(DV)___? What is the relationship between ____(IV)____ and ___(DV)___? Ex. What is the effect of the amount of caffeine on student performance in class? A scientific hypothesis should be a testable prediction about the effect of the IV on the DV. If _____________, then ____________ because….. Ex. If a student drinks more caffeine, then they will have higher test scores because they will be more awake. The independent variable, IV, is the change that is being made by the experimenter. Ask: What is it that I am going to change in this experiment? Ex. Amount of caffeine The dependent variable, DV, is the data that is collected or measured in this experiment. The DV occurs as a result of the change in the IV. Ask: What data am I collecting? Ex. Test scores A constant, C, is any part of the experiment that must stay the same for all trials in order to have a fair experiment. Ask: What did I keep the same for all trials? Ex. type of caffeine source, amount of sleep, student population tested, room temperature etc. A control is the part of the experiment that all the trials will be compared back to. This may not be present in all experiments. Ex. No caffeine |
