LEARNING ABOUT GEAR RATIOS CAN BE FUN
Dragster racing down DuBois Central Catholic’s middle school hallway taught students the importance of gear ratios and torque while being creative with Lego Mindstorm. Instructor Angela Edwards holds the ‘starting line’ in place while students ready their free design models. Fellow students wait their turns to test the speed of their ‘robot dragster.’
Edwards explains, “Students saw first-hand how changing gear ratios can affect speed and power!” After learning about friction and the center of gravity, and experimenting with slope by using protractors to measure angles, students then created ‘mountain climbers’ to see which ‘robot’ could climb the steepest incline.
By working in pairs, students utilized their soft skills, such as communication, listening, teamwork, and cooperation. Edwards concludes, “And, as always, patience and perseverance were present in great supply.”
