Core Skills Analysis
Science
Amelia mixed the hair‑dye chemicals and applied them to her mum's hair, observing how the colour changed from dark to blonde. She learned that hair dye contains pigments and oxidising agents that react with the natural colour of hair, demonstrating a chemical reaction. By watching the transformation over time, Amelia understood the concept of cause and effect in material changes.
Mathematics
Amelia measured the amount of dye and developer needed for the application, using the instructions on the package to ensure the correct ratio. She practiced addition and division when calculating how many millilitres of each component were required for the full set of hair. This activity reinforced her ability to work with units of measurement and follow numerical instructions accurately.
Art & Design
Amelia selected a blonde shade and considered how it would contrast with her mum's original hair colour, applying principles of colour mixing and value. She experimented with blending pigments to achieve a uniform tone, which helped her understand how primary and secondary colours interact. The hands‑on process enhanced her eye for visual balance and aesthetic outcome.
English (Communication)
Amelia read the product label, followed the step‑by‑step directions, and explained each stage to her mum, practicing clear oral communication. She also wrote down notes about the timing and results, developing her ability to record observations in a concise, organized way. This reinforced her reading comprehension and technical writing skills.
Tips
To deepen Amelia's learning, try a mini‑science experiment comparing different hair‑dye brands to see which reacts fastest, documenting results in a simple chart. Incorporate a budgeting activity where Amelia calculates the cost per millilitre of dye and compares it to other beauty products, linking maths to real‑world decisions. Extend the art focus by creating a colour‑wheel collage that includes the blonde hue alongside complementary shades, discussing why certain colours pair well. Finally, have Amelia write a short “how‑to” guide for a friend, reinforcing her English skills and encouraging reflective thinking about the process.
