If we think about science experiments, the image we form in our mind is that of a scientist in a white coat, or some students handling the vernier calipers. There is little curiosity about such experiments because students are already told what to do and what to expect as the result, before they enter the laboratory.Towever, there is no need for such a limitation. We can design science experiments by using simple and low cost materials. This book contains 100 such experiments cov ering different science concepts. Using these experiments, student will be able to understand thall science behind simple day-to-day activities. These experiments are also designed to be stunning and the outcomes are often different from what students expect.
