Actually science is a wonderful combination of theory and experiments. But it is impossible to understand the specifics of this subject without using it. So all theories are proved. Experiments have also been given to do this.In this book 71 + 10 New Science Projects Junior, the author has written about several important theories of science such as air pressure, volume, density, gravitational force and the surface area of a solid in a simple yet interesting language diction.In all the experiments in this book, such devices such as water glass, candle, balloon, tap etc. have been used, which are easily available to us. This book is very useful especially for small school children from 6 to 14 years. Children can easily enrich their knowledge by repeating these experiments in the presence of their parents. From class fifth to class ninth, students can increase their knowledge by repeating all the 81 interesting experiments given in the book in their home or school.Kids, go ahead and learn about science.
