To celebrate a century of amazing chemistry-related discoveries, we featured Chemistry as the theme of Science Alive 2015. This programme covered a wide range of activities including Science Drama Shows, Teacher Development Workshops, Family Workshops for parents to do experiments with their children, Student Workshops, as well as the well-received Family Days. This programme was jointly organised by the Hong Kong Science Museum, the British Council, the Education Bureau and the Hong Kong Education City Limited, and sponsored by the Croucher Foundation.
