Science Christmas Experiment

Bring science and creativity together with this fun, hands-on Christmas chromatography activity designed for KS2/KS3 (Year 5–9). Pupils explore how colours are made by separating the hidden dyes inside felt-tip pens, then turn their results into festive decorations.

This resource includes a simple step-by-step investigation guide. Chromatography paper is recommended, but everyday alternatives are also suggested to make the activity easy to run in any classroom or at home.

Resources Needed:
• Chromatography paper - available on amazon for around £6 (or white coffee filters as an alternative)
• Beaker / jam jar / any clear plastic container
• Water
• Pencil
• Ruler
• Paper clip or tape
• Felt-tip pens for testing

Pupils learn that felt-tip inks are mixtures of colours and use chromatography to split them apart. Once their chromatograms have dried, they cut out their designs and glue them onto Christmas baubles to create a take-home decoration. This blends science enquiry, observation, and seasonal craft in an accessible, engaging way.

Perfect for introducing mixtures and following a scientific method while keeping learning festive and fun.
