Experience a classroom-ready engineering challenge that integrates physical science and the Engineering Design Process. In this session, participants will investigate the wheel and axle as a simple machine by designing, building, and testing rubber band-powered cars. Through hands-on experimentation, participants will explore how wheel size influences speed, distance traveled, and motion. They will make predictions, conduct trial runs, measure distances, and collect data to identify patterns and draw evidence-based conclusions. By analyzing results and refining their designs, participants will develop an understanding of force, friction, motion, and energy transfer while strengthening their problem-solving, critical thinking, scientific reasoning skills, and increasing their fluency in using the Engineering Design Process. Attendees will leave with the knowledge, materials, and confidence to implement this hands-on STEM investigation in their own classrooms.
TAKEAWAYS:
Participants will build, test, and optimize a rubber band-powered car while collecting and analyzing data to determine how wheel size affects speed and distance, leaving with a classroom-ready engineering design challenge.
