Why Engineers Change One Variable at a Time

Crash Course Kids

In this engaging episode of Crash Course Kids, host Sabrina Cruz uses the analogy of a mobile video game to explain the fundamental engineering concepts of variables and outcomes. The video breaks down the scientific method of testing solutions, specifically focusing on why it is critical to isolate variables during an experiment to understand cause and effect. Through a "Catbot" slingshot game, viewers see a practical demonstration of how changing launch angle versus pull strength affects the result.
