STEM Club pupils explored key laboratory skills by investigating accuracy and precision, using pipettes to produce consistent circles on filter paper. They then observed microscale electrolysis before generating and capturing carbon dioxide, which was successfully used to extinguish candles, demonstrating its properties in a memorable and engaging way. STEM Club pupils also explored key laboratory skills by producing biodegradable plastic from potato starch and glycerine. They carefully measured and mixed ingredients, heated the solution, and observed the chemical changes that transformed a liquid mixture into a flexible bioplastic. Once set, pupils tested the material’s strength and flexibility, linking the practical work to real-world applications of sustainable materials and plastics, making the session both hands-on and environmentally relevant.
