Understanding Variables in Science Experiments: Independent, Dependent & Controlled #79775 (License: Personal Use)

This infographic breaks down the three fundamental variable types used in experimental design: independent variables (the factor deliberately changed, like the liquid given to plants), dependent variables (the measured outcome, such as plant height or health), and controlled variables (all other factors kept constant, like soil type, light, and temperature). Each is illustrated with a labeled diagram of a potted plant under different experimental conditions (A, B, C) to reinforce conceptual understanding.

Used in middle school, high school, or introductory college science curricula to teach experimental design; ideal for lesson slides, study guides, or educational websites where users seek foundational knowledge on the scientific method and hypothesis testing.
