For many years, chemistry has been considered the central science due to its significant connections and overlap with other sciences. If a scientific discipline involves matter, chances are that chemistry plays an important role. Therefore, we will always need people who have a good knowledge of chemistry. As expressed by Beach and Stone (1988) â€Å"chemistry education without laboratory is like painting without colors and canvas or learning how to ride a bike by reading its operating manual† (Tezcan and Bilgin, 2004). The study of chemistry in schools equips students with knowledge in the classroom and skills of conducting experiments in laboratories during practical sessions that are scheduled once a week for a period of two to three hours (MOH, 2001). 2.1.2 Hazards Chemical in the School E xperiments The teaching of chemistry at secondary school includes the use of hazardous chemical, which is essential for the understanding of chemistry fundamentals.
