Science Club was full of excitement this week as our Year 6 leaders helped Year 2 pupils learn about chemical reactions and why they are important in everyday life, particularly in cooking.
The session began with discussions about how to identify when a chemical reaction has taken place. The children learnt to look for signs such as gases being produced, changes in texture and changes that cannot easily be reversed.
To put their learning into practice, the children carried out a tasty investigation by testing two biscuit recipes. One recipe contained bicarbonate of soda, while the other did not. Before baking, the children made predictions about what they thought would happen and discussed the role of bicarbonate of soda in baking.
Once the biscuits were cooked, the children carefully compared the results. They observed differences in the texture, appearance and size of the biscuits and discovered how the chemical reaction caused by the bicarbonate of soda affected the final product. This helped them understand why certain ingredients are important in cooking and baking.
The Year 6 leaders did a fantastic job of explaining scientific ideas and supporting the younger children throughout the investigation. Meanwhile, the Year 2 pupils demonstrated great curiosity and enthusiasm, asking thoughtful questions and making careful observations.
It was a fun and engaging session that combined scientific enquiry with a delicious real-life application of chemistry.
