hypothesisAn educated guess about how things

work.

Most of the time a hypothesis is written like this: "If _____[I do this] _____, then _____[this]_____ will happen." Write an example from your Vitruvian man lab.

Your hypothesis should be something that you can actually test. Testable means you can measure both "what you do" and "what will happen."

theoryA set of statements or principles devised

to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.

Example: Big Bang Theory

Parts of an ExperimentControl – The part of an experiment that does not change.

Variable – The part of an experiment that changes. Make sure you test only ONE variable for each experiment.

Variables

Independent variable - the thing that is changed by the scientist.

Dependent variable - what you measure in the experiment and what is affected during the experiment.

Controlled variables - are quantities that a scientist wants to remain constant.

ObservationObservations are recorded facts

about what you see during the experiment.

Quantitative – Results are numerical and have a unit. (ex: 5 meters, 45 seconds)

Qualitative – Results are descriptive. . (ex: the litmus paper turned red)

Conclusion of an ExperimentA brief statement about the results of the experiment. It states that the hypothesis was correct (proved) or incorrect (disproved).
