    Study Notes

    The Scientific Method

    • A hypothesis is a proposed explanation for a phenomenon, and it guides the investigation and experimentation process.

    Importance of Control Group

    • A control group is a standard against which to compare the experimental group, allowing researchers to isolate the effect of the independent variable.
    • The control group ensures that any changes observed in the experimental group are due to the independent variable, rather than other factors.

    Purpose of an Experiment

    • The primary purpose of an experiment is to test a hypothesis and determine whether it is supported or rejected.

    Predictions and Hypothesis

    • The step of the scientific method that involves making predictions based on the proposed explanation is the hypothesis.

    Role of Control Group

    • The purpose of a control group is to provide a baseline for comparison, allowing researchers to determine whether the independent variable has a significant effect.

    Variables in an Experiment

    • The dependent variable is the variable being measured or observed in an experiment, and its value changes in response to the independent variable.
