  1. Scientific Hypothesis, Model, Theory, and Law

    A hypothesis is an educated guess, based on observation. It's a prediction of cause and effect. Usually, a hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven but not proven to be true. Example: If you see no difference in the cleaning ability of various laundry detergents, you might ...

  4. Hypothesis Definition (Science)

    A hypothesis is an explanation that is proposed for a phenomenon. Formulating a hypothesis is a step of the scientific method. Alternate Spellings: plural: hypotheses. Examples: Upon observing that a lake appears blue under a blue sky, you might propose the hypothesis that the lake is blue because it is reflecting the sky.

  5. Hypothesis

    In chemistry, hypotheses often predict how changes in one variable will affect another, such as temperature changes affecting reaction rates. Developing a good hypothesis involves extensive background research and understanding of the existing literature. A hypothesis is typically framed as an 'if-then' statement to clearly define expected ...

    Definitions. A (causal) hypothesis is a proposed explanation. A prediction is the expected result of a test that is derived, by deduction, from a hypothesis or theory. A law (or rule or principle) is a statement that summarises an observed regularity or pattern in nature.

  7. Hypothesis Examples

    A hypothesis proposes a relationship between the independent and dependent variable. A hypothesis is a prediction of the outcome of a test. It forms the basis for designing an experiment in the scientific method.A good hypothesis is testable, meaning it makes a prediction you can check with observation or experimentation.
