Projects
Secret Spell Scroll
Children invent a symbol code, write a hidden spell in white wax crayon and reveal it with watery paint. They learn how a substitution cipher works and why wax resists water, so the paint only soaks into the bare paper.
Cardboard Gravity Coin Sorter
Children discover physical sorting algorithms by using gravity and cut-out sizes to separate mixed coins automatically.
Symmetry Butterfly Puzzle
Making a butterfly whose wings match exactly teaches line symmetry, where one half mirrors the other. Recognising patterns and mirror images is an important part of maths and visual problem-solving.
Binary Code Name Bracelet
Threading two colours of bead in patterns of eight shows how computers store every letter as a secret code of just two symbols. Children discover that ones and zeros can spell out anything, including their own name.
