Independent, Dependent & Controlled Variables Explained Simply #3281570 (License: Personal Use)

This educational infographic clearly distinguishes the three key variables in a scientific experiment: the independent variable (what the researcher changes, shown with a hand adjusting a dial), the dependent variable (what is observed or measured, illustrated by an eye and magnifying glass), and the controlled variable (what remains constant, marked with a prohibition symbol over a changing element). Each term is bolded, color-coded, and paired with intuitive icons to reinforce learning.

Used in middle/high school science curricula, lab handouts, teacher presentations, and online STEM resources to help learners grasp foundational experimental design concepts; matches user intent to quickly understand or teach variable types.
