Science Experiments for Class 5

You cannot deny the fact that, “Science is amazing!” Biological concepts of life, natural aspects of our planet Earth, optical illusions created by light & mirror, and candle underwater experiment – all of these are as fascinating as studying the theory of Science. Being a Fifth Grade student, this sense of wonder often might have drawn you towards various scientific activities and experiments.

Let’s explore some of them for you, so that next time when you participate in a Science Exhibition, your Project becomes one of a kind.
