Chemistry is a practical oriented discipline of science.  In the NSS Chemistry and Combined Science (Chemistry Part) curricula, students are expected to develop understanding of various experimental techniques and chemical analyses through different learning and teaching activities.  Other than real-time demonstration and hands-on experience in practical lessons, instruction in mode of multimedia can also serve as a useful tool to familiarise students with the experimental techniques and methods. 


The videos included here have demonstrated the procedures of the selected experimental methods supplementing with the simple theoretical description.  They can be used by students for familiarizing themselves with the corresponding experimental techniques and methods before conducting experiments, practical tests of School-based Assessment and the investigative study, as well as used by teachers for teaching and pre-experiment instruction.
