Publisher’s Note

In line with a number of books and best-sellers in Science for children, particularly the school students, V&S Publishers have now come up with the following two, absolutely new and thrilling books on Science Projects, namely 71+10 New Science Projects Junior and 71+10 Science Activities.

In the book, 71+10 Science Activities , the author has explained the simple laws and principles of Science, such as: Air Force, Pressure, Weight, Emulsification, Osmosis, Gravity and Motion, Rotation, Resisting Motion, Stored Energy, Vibrations, Good and Bad Conductors of Electricity, Experiments with Magnets, Light and Sound for children, and projected them in a very simple and lucid language for the readers-- particularly the school kids who can easily perform these activities at home or school , of course with the help and guidance of their parents, elders or teachers.

Basically, the main idea behind publishing such books are that they are educative, informative as well as interesting and full of fun. Children of all ages, particularly from 6 to 13 can perform these fun-filled activities and learn as well - the basic principles of Science easily and quickly. Moreover, as we are all aware of the fact that Science cannot be understood properly and learnt theoretically without practical demonstrations or experiments - in order to test and prove the different scientific laws and theories.

Therefore, this book will enable all its readers, especially the young ones to learn as well enjoy performing all the 81 fascinating Science Activities listed in the book, each explaining or proving some scientific theory or law - making it really worth reading!

1 Air Force

Things Required:

Sheet of paper

Directions:

Do you know a fast way to stick a piece of paper to your hand without using any glue or tape? Would you believe that air will do the job? Well, it will! Just follow the steps below.

1. Hold your arm straight at your side. Turn your hand so that the palm faces forward.

2. Press a flat sheet of paper to your palm, using your other hand. Now start running as fast as you can and take away the helping hand. The paper will stay in place as you run.

Explanation:

Even though you can’t see air, it is a substance, just like anything else, and it exerts a force against objects. When you ran with the paper, you created a force pushing against the air. The air pushed back against the paper and held it in place against your hand. Hence, we conclude that air too, has and exerts force.

2 Air Pressure Difference

Things Required:

A sheet of typing paper

Directions:

1. Hold an 21 x 28 cm sheet of typing paper high above your head. Use both hands to grasp the paper. Let go. The paper will scoot in various directions and probably turn over.

2. Now make two folds in the long side of the paper, first, 2.5 cm inward, then, 2.5 cm again.

3. Hold the paper over your head, but make sure that the folded edge is at the front, and on the underside, of the sheet. Gently push the paper as you release your grip. The paper will not turn over
