STEM Club Sparks Curiosity with Colourful Chemistry

This week, our STEM Club pupils embarked on a fascinating experiment that combined science and creativity. The children explored the natural properties of red cabbage by extracting its pigment and using it as a natural pH indicator, showcasing how science can lead to beautiful and unexpected results.

The session began with an introduction to acids, alkalis, and pH levels, helping the children understand the science behind what they were about to do. Armed with pestles and mortars, the young scientists ground pieces of red cabbage into a paste before adding warm water to extract the vibrant purple pigment. They carefully filtered the mixture to collect the pure cabbage filtrate, learning essential lab techniques in the process.

Once their natural indicator was ready, the children used it to create colourful scientific art. By painting the filtrate onto paper and adding acids like vinegar and alkalis like bicarbonate of soda, they observed how the indicator changed colour, ranging from red and pink hues in acidic solutions to greens and blues in alkaline ones. This hands-on activity not only reinforced their understanding of chemical reactions but also allowed them to unleash their creativity.

The session was a perfect blend of learning and fun, sparking curiosity about chemistry and encouraging critical thinking. The children were thrilled to see science come to life in such an engaging way, and the vibrant artworks they created were a testament to their enthusiasm and innovative spirit.

Well done to all our budding scientists for their curiosity and effort!
