Core Skills Analysis
Science
- Zenia evaluated the absorbency and weight of cotton wool versus toilet paper, demonstrating an understanding of material properties.
- She observed how different fibres react when adhered to cardboard, noting the importance of cohesion and surface texture.
- The choice to purchase cheaper toilet paper reflects an awareness of cost‑benefit analysis linked to material efficiency.
- By testing a prototype wing, Zenia practiced the scientific method: hypothesising, experimenting, and concluding which material performed best.
Design & Technology
- Zenia followed a full design cycle: research, sketching, prototyping, testing, and final production of the wing.
- She repurposed cardboard from an old box, showing resourceful use of sustainable, recyclable materials.
- The decision to keep the project cost‑effective illustrates budgeting skills and material sourcing considerations.
- Cutting the cardboard to a custom outline and gluing tissue demonstrates practical skills in measuring, cutting, and assembling components.
Mathematics
- Zenia measured and scaled the wing dimensions from a smaller cardboard model to the final size, applying concepts of ratio and proportion.
- She calculated the area needed for the tissue covering, engaging with geometry and area estimation.
- Accurate cutting required precision with lengths and angles, reinforcing skills in using a ruler and protractor.
- The project involved estimating material quantities, linking to multiplication and estimation strategies.
Art
- Zenia drew the wing outline before construction, practising composition, line work, and visual planning.
- Choosing tissue for its translucency added an aesthetic layer, showing sensitivity to texture and visual effect.
- The final wing’s successful appearance demonstrates an understanding of colour contrast and surface finish.
- Documenting the process in descriptive language strengthens visual‑verbal communication skills.
Tips
To deepen Zenia’s learning, encourage her to test additional everyday materials (e.g., fabric, foam, thin plastic) and record a comparison chart of strength, flexibility, and weight. Next, have her attach the wing to a simple harness and experiment with lift by attaching light weights to see how different materials affect buoyancy. Incorporate a reflective journal where she sketches design revisions, notes observations, and explains why each change was made. Finally, organise a mini‑exhibit where Zenia presents her wing, discusses the design choices, and answers peer questions, reinforcing communication and presentation skills.
