Core Skills Analysis
Mathematics
- Calculated estimated costs for battery packs, motors, and materials, applying multiplication of unit prices by quantity.
- Created a simple profit‑and‑loss statement, using addition and subtraction of revenues, expenses, and taxes.
- Converted energy consumption figures from kilowatt‑hours to megajoules, practicing unit conversion and decimal operations.
- Plotted projected sales growth on a line graph, interpreting slopes to understand rate of change.
Science
- Explored how electric motors convert electrical energy into mechanical motion, linking concepts of magnetism and circuitry.
- Investigated battery chemistry (lithium‑ion vs. lead‑acid), discussing electron flow, capacity, and environmental impact.
- Examined the principle of regenerative braking, noting how kinetic energy is recaptured and stored.
- Discussed renewable energy sources that could power charging stations, connecting solar and wind concepts to real‑world applications.
Language Arts

- Compared the environmental policies of different countries regarding electric vehicle incentives.
- Analyzed how consumer demand and government regulation shape the automotive industry.
- Considered ethical responsibilities of a business owner, such as sustainability and fair labor practices.
Technology & Engineering
- Designed a basic schematic of an electric vehicle drivetrain, labeling components like inverter, motor, and battery pack.
- Evaluated trade‑offs between vehicle range, weight, and cost, applying systems‑thinking principles.
- Explored CAD software basics to sketch a simple vehicle body, reinforcing spatial visualization skills.
- Tested a miniature prototype on a ramp to observe torque and speed, recording data for iterative improvement.
Tips
To deepen the learning, have your child conduct a market‑research survey of family members to gauge interest in different EV features, then graph the results. Next, guide them in building a cardboard model of their vehicle and calculate its surface area to estimate paint costs, integrating geometry with budgeting. Invite a local engineer or a virtual tour of an EV manufacturing plant to connect theory with real‑world practice. Finally, set a weekly "innovation journal" where they reflect on challenges faced, solutions tried, and new ideas, reinforcing metacognitive skills.
