Core Skills Analysis
Mathematics
The student measured the truck chassis and calculated the required lift height, using proportional reasoning to determine the dimensions of each component. They applied algebraic formulas to compute the torque needed for the lift kit and performed unit conversions between inches, centimeters, and pounds. Budgeting the project required them to add, subtract, and multiply costs for materials, while estimating waste percentages involved percentage calculations. Throughout the build, they graphed load versus displacement to verify the design met safety thresholds.
Science (Physics)
The student examined the principles of force, torque, and leverage, applying Newton's second law to predict how the lift kit would support the truck's weight. They explored material properties such as tensile strength and thermal conductivity when selecting steel for the frame and evaluating welding heat input. By testing the completed kit, they observed real‑world outcomes versus theoretical predictions, reinforcing concepts of experimental error and data analysis. The activity also introduced concepts of energy transfer during welding, linking chemical reactions to practical engineering.
Technology/Engineering
The student created a detailed CAD model of the lift kit, learning to translate a 2‑D sketch into a 3‑D assembly with precise tolerances. They programmed the CNC table, generating G‑code and troubleshooting feed rates to achieve clean cuts, which deepened their understanding of computer‑controlled manufacturing. Welding the fabricated parts required them to follow safety protocols, select appropriate joint types, and execute bead placement, integrating hands‑on craftsmanship with digital design. The entire process embodied the engineering design cycle: define the problem, brainstorm, prototype, test, and iterate.
Language Arts
The student documented each step of the project in a written log, practicing clear technical writing and organization of procedural information. They composed a project report that included introductions, method explanations, results, and reflections, strengthening expository writing skills. By labeling CAD drawings and creating a parts list, they used precise terminology and labeling conventions common in technical communication. The reflective portion required them to evaluate challenges and propose improvements, fostering critical thinking and articulate self‑assessment.
Tips
Tips: Have the student create a scaled physical mock‑up of the lift kit using cardboard to explore spatial reasoning before CNC cutting. Organize a mini‑workshop where peers critique the CAD model and suggest alternative joint designs, encouraging collaborative problem‑solving. Incorporate a budgeting spreadsheet activity that tracks real‑time expenses and compares them to the original estimate, reinforcing financial literacy. Finally, ask the student to produce a short video walkthrough of the build, practicing multimodal communication and digital storytelling.
