🔬 Diffusion, Dissection and the Respiratory System in Science 🧪

It has been another exciting and practical week in Science, with both our IGCSE and KS3 students taking part in hands-on investigations to deepen their understanding.

In IGCSE Science, students explored diffusion in action through a detailed practical experiment. Using visking tubingto represent a partially permeable membrane, they added a glucose solution and suspended it in boiling tubes of water at different temperatures. Students then tested the surrounding water using Benedict’s Solution to determine how long it took for the glucose to diffuse out.

Through this investigation, students discovered that the rate of diffusion increases with temperature, as particles gain more kinetic energy and move more quickly. It was a fantastic opportunity to link theory with real scientific observation and develop practical investigation skills.

In KS3 Science, students took part in a chicken wing dissection to identify muscles, tendons and ligaments. This allowed them to see first-hand how an antagonistic muscle pair works together to bend and straighten a joint, bringing their learning to life in a memorable way.

Students also began learning about the respiratory system, building their own bell jar lung models to demonstrate how ventilation works. This practical activity helped students visualise how the lungs expand and contract during breathing.

It has been a brilliant week of hands-on science, with students showing great curiosity, engagement and understanding across all topics. 🔬
