Teach Engineering: The Balancing Act

Curated by ACT

Students are given the opportunity to visualize and interact with concepts they have already learned, specifically algebraic equations and solving for unknown variables. Students construct a balancing seesaw system (LEGO Balance Scale) made from LEGO MINDSTORMS parts and digital components to mimic a balancing scale. They are given sample algebraic equation problems to analyze, configure onto the balance scale, and evaluate by manipulating LEGO pieces and gram masses that represent terms of an equation such as unknown variables, coefficients and integers. Digital light sensors, built into the LEGO Balance Scale, detect any balance or imbalances displayed on the balancing scale. The LEGO Balance Scale interactively issues out a digital indication of balance or imbalance within the system to students. If unbalanced, students are encouraged to continue using the LEGO Balance Scale until they're correct and confident in their understanding of solving for algebraic equations. The goal of this activity is for each student to be encouraged and confident in solving algebraic equations by fundamentally understanding the basics of algebra and real-world algebraic applications.
