On 25 May, our Secondary 1 Students headed for a Learning Journey to the Science Centre. Students attended the crime lab workshop before going to the science centre exhibitions – climate challenge and marine alcove. There they learned how forensic science is used to solve crimes by analysing evidences using physical and chemical techniques, as well as a key chemistry lesson in how to describe acidity, neutrality and alkalinity in terms of the pH scale.  It was a good lesson for students who might be thinking of becoming forensic scientists in future!
