Core Skills Analysis
Mathematics
- Grace measured and recorded lengths of wood, PVC pipe, and decorative components, converting centimetres to metres for her project plan.
- She applied geometry by calculating the angles needed for a stable base and a sloped roof, using concepts of right‑angled triangles.
- Grace created a simple budget, adding the prices of all Bunnings supplies and checking the total against a pre‑set allowance.
- She logged the time spent on each building stage, plotted the data on a bar graph, and identified which steps could be done more efficiently.
Science
- Grace investigated stability and centre of gravity by testing different base widths and noting which designs stayed upright.
- She explored light behaviour by installing tiny LED lights inside the lighthouses and observing how illumination diffused through painted glass.
- Grace compared material properties, noting how wood absorbed moisture versus PVC’s resistance to water during a rain simulation.
- She conducted a simple experiment on wind resistance, using a fan to see how shape and weight affected the lighthouse’s wobble.
Design & Technologies
- Grace followed the Design Cycle: research (looking at real lighthouses), planning (sketches), creating (building), testing (stability checks), and evaluating (making improvements).
- She produced technical drawings with scaled dimensions before cutting any material, reinforcing precision and planning skills.
- When a prototype tipped, Grace problem‑solved by widening the base and adding cross‑bracing, demonstrating iterative design.
- She considered sustainability, selecting recyclable PVC and locally sourced timber, and recorded the environmental benefits of each choice.
Visual Arts
- Grace used colour theory to choose contrasting paints that make the lighthouses pop against garden greenery.
- She added decorative patterns and textured brushwork, enhancing visual interest and personal expression.
- Grace evaluated the overall aesthetic by arranging the lighthouses in the garden and adjusting placement for visual balance.
Tips
Extend Grace’s lighthouse project by organizing a field trip to a real coastal lighthouse where she can observe professional engineering, historic design, and maritime navigation in action. Back at home, have her keep a math journal documenting measurements, cost comparisons, and time logs for each new build, turning data into reflective graphs. In science class, set up a controlled experiment testing different waterproof coatings on her models, recording which best resists simulated rain. Finally, host a mini‑exhibition in the neighbourhood where Grace presents her designs, explains her design‑cycle process, and invites peers to vote on the most creative lighthouse, reinforcing communication and public‑speaking skills.
