Students of Presidium had an interactive session – Making a charge detector, the activity was undertaken to make the students understand that science is fun. Under the guidance and motivation of their parents and teacher, they conducted activities during the science period. Students performed activities to experiment with the behaviour of charged bodies with uncharged or charged particles. The activity encouraged students to observe the characteristics of positive and negative charges. Overall the activity was a wonderful opportunity to get their doubts clear. The activity promoted active participation and learning by doing experience.
