🔬 Investigating Pressure, Solubility and Food Tests in Science 🧪

It has been another exciting week of practical learning in Science, with both KS3 and IGCSE students exploring how scientific ideas can be demonstrated through hands-on investigations.

In KS3 Science, students learned about gas pressure and investigated how changing temperature affects pressure using a simple but effective experiment. By placing a balloon over the opening of a plastic bottle and moving it between hot and cold water baths, pupils were able to observe the balloon expand and deflate as energy was added to and removed from the gas particles. Students loved seeing the immediate changes and were able to link their observations to the movement and energy of particles.

Students also explored the difference between pure substances and mixtures, carrying out an investigation into the solubility of sugar in hot and cold water. Through predicting outcomes and observing results, pupils developed their understanding of how increasing temperature affects the kinetic energy of particles and, in turn, solubility. It was fantastic to see how accurately students were able to hypothesise and explain their findings.

In IGCSE Biology, students focused on biological molecules and the food tests used to identify them. Learners worked carefully to prepare food samples, developing practical skills such as filtration, before using a range of reagents to test for starch, glucose, protein, fats and vitamin C.

Students observed positive and negative test results based on colour changes and then analysed their findings, applying their understanding to different contexts. The practical required careful observation, teamwork and attention to detail, and students approached the investigation with great focus and enthusiasm.

It has been a brilliant week of practical science, with students continuing to develop strong investigative and analytical skills. 🔬
