Core Skills Analysis
Mathematics
Megan measured the distance between the wheel rim and the brake pads using a ruler, calculated the required adjustment in millimetres, and recorded the values in a notebook. She compared the left‑hand and right‑hand measurements to determine the discrepancy and used subtraction to find the exact amount of turn needed on the axle nuts. By applying basic geometry, she ensured the wheels were parallel to the frame, reinforcing concepts of measurement, precision, and spatial reasoning.
Science (Physics)
Megan explored how wheel alignment affects the forces acting on a moving bicycle, noticing that mis‑aligned wheels create uneven friction and make steering harder. She observed that a properly aligned wheel reduces drag and allows smoother motion, linking the activity to concepts of friction, torque, and balanced forces. The hands‑on experiment helped her understand how small mechanical adjustments can change the efficiency of motion.
Design & Technology
Megan identified the components of the bike’s axle and quick‑release skewer, then followed a step‑by‑step process to tighten or loosen them for correct alignment. She evaluated the design of the wheel hub and brake system, deciding which tool (Allen key or wrench) was appropriate for each adjustment. This activity fostered problem‑solving, tool safety, and an appreciation of how engineered parts work together.
Physical Education
Megan practiced fine motor skills while handling small tools, maintaining steady hand‑eye coordination throughout the alignment. She tested the bike after each adjustment, feeling the difference in steering stability and balance, which enhanced her proprioception and spatial awareness while riding.
Tips
To deepen Megan's learning, have her create a simple data table tracking wheel measurements before and after each adjustment, then graph the changes to visualize improvement. Next, set up a short “bike lab” where she tests ride distance and effort with mis‑aligned versus aligned wheels, recording time and perceived exertion. Finally, encourage her to design a mini‑poster explaining how wheel alignment influences safety and efficiency, using diagrams and real‑world examples.
