Sink and float is one of the most popular and fun concepts of science that pre-schoolers love to explore. Our Senior K.G. students enjoyed a hands-on experiment on float and sink. Children experimented with objects like a piece of wood, a stone, plastic straw, twig, paper etc. which were put into a tub of water. Students got an idea about the varying weight, size and materials that they are made of. They observed keenly and noted the ones that floated and the ones that sank. This was an enjoyable activity which helped our students get a better clarity on this intrinsic property of all materials around us.
