Core Skills Analysis
Science (Working Scientifically)
- Child formulated a testable question about how turmeric concentration affects paint colour, showing inquiry skills (ST3-1WS-S).
- Child planned and carried out systematic mixes of turmeric and water in different ratios, observing changes in hue and opacity.
- Child recorded observations for each material (plastic, paper, cloth) and compared which absorbed the dye most effectively.
- Child summarised the data in a simple chart and communicated conclusions about the best concentration and substrate.
Design and Production (Design & Production Skills)
- Child selected appropriate tools (measuring spoons, mixing bowls) and materials to develop a homemade dye, meeting ST3-2DP-T.
- Child experimented with different substrates, evaluating how each material’s surface influences the final paint finish.
- Child iterated the recipe by adjusting turmeric concentration, demonstrating problem‑solving and refinement of a product.
- Child documented the process with sketches and notes, creating a prototype that could be used for future art projects.
Material World (Properties of Materials)
- Child explored how the porosity and texture of plastic, paper, and cloth affect dye absorption, aligning with ST3-7MW-T.
- Child noted that cloth fibers held more colour than smooth plastic, linking material structure to function.
- Child considered the durability of the colour after drying, beginning to think about material suitability for different uses.
- Child’s observations lay groundwork for future investigations of heat or friction on material properties (ST3-6MW-S).
Tips
Encourage child to design a mini‑research poster that compares the three materials side‑by‑side, adding a rating scale for colour intensity and durability. Next, set up a ‘colour‑mixing lab’ where child can blend turmeric with other natural pigments (e.g., beetroot, spinach) to discover new shades and record the ratios. Introduce basic measurement concepts by having child weigh the turmeric before mixing, reinforcing math skills. Finally, plan a small community art project where the homemade paint is used on recycled cardboard, linking creativity with sustainability.
