Core Skills Analysis
Mathematics
- Measured inner and outer diameters of rings using calipers, applying concepts of circumference (C = π d) and radius.
- Converted measurements between millimetres and centimetres, reinforcing unit conversion and decimal place value.
- Calculated material waste by estimating the volume of brass needed for each design, linking to area and volume formulas.
- Used proportional reasoning to scale a sketch design up or down while keeping the ring's thickness consistent.
Science
- Investigated the physical properties of brass (alloy of copper and zinc), noting its malleability, ductility, and thermal conductivity.
- Observed how heating (annealing) changes the metal’s crystal structure, connecting to concepts of phase change and kinetic energy.
- Applied safety science by identifying hazards (sharp edges, hot tools) and using appropriate protective equipment.
- Explored chemical reactions involved in patination (e.g., applying liver of sulphur) to create colour variations on the metal surface.
Design & Technologies
- Followed the design cycle: research, ideation, sketching, prototype, testing, and final production of a functional jewellery piece.
- Selected appropriate tools (files, hammers, soldering iron) based on material properties, demonstrating knowledge of tool‑material interactions.
- Evaluated the ergonomics and durability of the ring, considering comfort, strength, and aesthetic appeal.
- Documented each stage with photos and notes, building a technical portfolio that mirrors industry practice.
Visual Arts
- Applied principles of balance, rhythm, and contrast when arranging decorative elements on the jewellery.
- Explored colour theory through the use of different patinas and metal finishes (polished, brushed, antiqued).
- Developed a personal visual style by experimenting with motifs, textures, and surface patterns.
- Critiqued finished pieces using visual vocabulary, linking artistic intent to the physical outcome.
English / Language Arts
- Read and interpreted step‑by‑step procedural instructions, enhancing comprehension of technical text.
- Wrote reflective journal entries describing challenges, solutions, and future improvements, fostering narrative skills.
- Prepared a concise product description for each ring, practicing persuasive writing and audience awareness.
- Engaged in peer discussion, giving and receiving constructive feedback using appropriate academic language.
Tips
To deepen the learning experience, have the student research the history of brass jewellery across cultures and present a short multimedia showcase. Next, set up a budgeting exercise where they calculate the cost per gram of brass versus alternative alloys, then design a cost‑effective but aesthetically pleasing piece. Incorporate a math challenge by asking them to create a scaling chart for converting a 2‑D sketch into a 3‑D model using geometry formulas. Finally, organise a mini‑exhibition where the student explains the scientific principles behind annealing and patination to family members, turning the workshop into a public‑speaking opportunity.
