Class iv A students were given flash cards of various light sources. They identified and classified them as man-made and natural sources.
Students learnt the importance to measure light intensity in their life as to click a photograph or during a cricket match.
Students also arranged the given light sources with least light intensity to maximum light intensity.
Light from the source falls on the object . The light gets reflected from the object and enters our eyes so we see the object. Students see a dark box using a torch and locate the object as a number of books in the dark box.
