This week in the Science Department, some of our Year 8 students impressed us as they tackled a classic chemistry challenge: separating a mixture of sand and salt. Year 8 are currently learning about atoms, elements, compounds and mixtures and have looked at various separating techniques. One of our aims at PGHS is for the girls to be independent so they were given access to a wide range of lab equipment and, with minimal guidance, were asked to plan and carry out their practical. Tasked with designing and carrying out the practical themselves, the students showed creativity, teamwork and impressive scientific thinking. From planning their methods to selecting appropriate equipment and adapting where necessary, each group approached the task with enthusiasm and a keen sense of inquiry. Using filtration, evaporation and a good deal of patience, the girls successfully separated the sand from the salt, learning not just about physical separation techniques but also about the scientific process itself. It was fantastic to see them discussing ideas, refining their methods and problem-solving in real time. We focused on the importance of the proper use of equipment to ensure a high purity of product. This process of planning a suitable method, as well as hopefully being an enjoyable lesson, is developing a key skill that the students will need for their GCSEs, as well as in A-levels, degree and scientific careers if they choose to pursue one.
