Science is a logical, systematic understanding of things to enhance our knowledge. There are different branches of science; chemistry is one, which enhances understanding of physical phenomena on the basis of theories and observations, and experiments. So in order to boost understanding of the concept of Exothermic and Endothermic reactions in Grade X, the T-chart activity was performed in class. T-Chart is a graphic organizer that examines two facets of a topic, like the pros and cons associated with it, its advantages and disadvantages, facts vs. opinions, etc. By listing the topics as headings for the two columns and writing down several facets that are valid for both options, it’s easy to make a comparison. Students of grade X enthusiastically participated in the activity and wrote the points of difference between them along with examples by writing Chemical Equations.
