One of the key experiments involved measuring the amount of gas produced during a reaction within a set timeframe. Using an upturned measuring cylinder, students collected the gas and tracked its volume, gaining insight into the relationship between reaction conditions and gas production.

In another experiment, students investigated the effect of concentration on reaction rates by observing a colour change. By mixing sodium thiosulphate with hydrochloric acid, the students timed how long it took for a cross beneath the reaction vessel to disappear, signifying the completion of the reaction. By using varying concentrations of hydrochloric acid, students were able to see first-hand how concentration affects the rate at which reactions occur.

These engaging experiments not only enhanced students' understanding of key scientific principles but also allowed them to develop important skills in conducting experiments and analysing results.
