Verified step by step guidance

Understand the scientific method: It involves making observations, formulating a hypothesis, conducting experiments, and analyzing results to draw conclusions.

Identify the key components of a controlled experiment: A controlled experiment tests a hypothesis by manipulating one variable (independent variable) while keeping other variables constant to observe the effect on another variable (dependent variable).

Recognize the importance of independent and dependent variables: The independent variable is the one you change, and the dependent variable is the one you measure or observe to see the effect of the change.

Design a controlled experiment: Choose a hypothesis to test, decide on the independent and dependent variables, and plan how to control other variables to ensure a fair test.

Conduct the experiment and analyze results: Perform the experiment, collect data on the dependent variable, and analyze the results to determine if they support the hypothesis.
