Science Activity for Students of Class 8 To ignite the young minds of our students of class 8 A and 8 B and help them retain their interest in science, a group activity was arranged for them. Our students used various materials like disposable plastic containers, sharpened pencils, carbon rods from dry cells, lemon juice and such items to demonstrate the process of electrolysis. They also made different circuits to verify the magnetic effect of electric current. Each group was graded for this activity based on their overall presentation.
