Laboratory activities have long had a distinctive and central role in the science curriculum. Science educators have suggested that many benefits accrue from engaging students in science laboratory activities. Since the end of the 19th century, when schools began to teach science systematically, the science laboratory has become a distinctive feature of science education.
Practical work in Chemistry is used to engage students in investigations, discoveries, inquiries, and problem-solving activities. The laboratory is designed to help students gain a better idea of the nature of science and scientific investigation by emphasizing the discovery approach. In addition, it gives students an opportunity to observe chemical systems and to gather data useful for the development of principles subsequently discussed in the textbooks and in class.
