Year 11 Chemistry

Year 11 Chemistry students brought polymer science to life through a hands-on practical investigation using sodium alginate to create boba balls with a range of different textures and consistencies. The activity gave students the opportunity to explore the fascinating world of polymers and investigate how chemistry is applied in everyday materials and food production.
Throughout the experiment, students adjusted polymer additives and carefully observed how changes in chemical composition affected the final product. By testing different combinations and recording their observations, students developed a deeper understanding of concepts such as molecular structure, cross-linking and the properties of polymers. The practical nature of the lesson encouraged students to think critically, problem-solve and apply their theoretical knowledge in a real-world context.
As the investigation progressed, students demonstrated significant growth in both their scientific understanding and practical laboratory skills. Many became more confident in following experimental procedures, making predictions and analysing results, while also learning the importance of precision, teamwork and safe laboratory practices. The activity also highlighted how chemistry plays an important role in industries such as food science, medicine and manufacturing.
The lesson was an engaging and memorable way for students to connect classroom theory with real-life applications, while fostering curiosity and enthusiasm for scientific discovery. It was fantastic to see students actively experimenting, collaborating and developing a greater appreciation for how chemistry shapes the materials and products we encounter every day.
