Core Skills Analysis
Science
Micah printed a glider on a 3D printer using a design created by someone else, and the printed part did not fly as expected. He observed that the failure was likely due to the material strength, weight distribution, and the precision of the printed layers. By reflecting on the outcome, Micah learned how physical properties of matter affect real‑world objects and why engineering designs often require testing and revision.
Mathematics
Micah examined the dimensions listed in the glider’s digital file and compared them to the actual printed piece, using fractions and decimals to calculate scaling adjustments. He performed measurements in millimeters, converted them to centimeters, and used basic ratio reasoning to decide how to modify the wings for better lift. Through these calculations, Micah practiced rational number operations and applied geometry concepts to a tangible engineering problem.
Tips
Encourage Micah to redesign the glider by sketching a new wing shape and estimating the required material volume before printing. Have him experiment with different filament types (e.g., PLA vs. PETG) to see how material density influences flight. Integrate a simple flight test journal where he records measurements, predictions, and outcomes, turning each print into a data‑driven science investigation. Finally, connect the design process to real‑world engineers by researching how aircraft wing profiles are tested in wind tunnels.
