In fact experimentation or experimentation experiments conducted in the field are essential part of any scientific study or research. Through easy and interesting experiments given in this book, the author has tried to simplify the science. All the experiments given in the book are based on scientific facts such as experiments related to atmospheric pressure, high and low temperature, solid, liquid and gaseous freezing and melting, gravitational force, magnetism, electricity, etc. Students will be able to understand the related principles well by performing these experiments in their homes or schools under the supervision of teachers, parents and elders. The language of the book is simple and all the given experiments have been explained. These experiments are based on scientific facts. With the help of this book, you will be able to fulfill the quest of your scientific curiosity.
