Description

A study of science and scientific theories and laws is almost incomplete without relevant and methodical Experiments. In fact Experiments are an inseparable part of any Scientific Study or Research. In this book, the author has tried to simplify science to the readers, particularly the school going students through easy and interesting experiments. All the experiments given in the book are based on some scientific phenomena or other such as atmospheric pressure high and low temperatures boiling freezing and melting points of solids liquids and gases gravitational force magnetism electricity solubility of substances etc. Thus read each of these fun - filled experiments and carry it out in your homes or schools under the supervision and guidance of your teachers, parents or elders. The language used in the book is simple and all the experiments have been illustrated with relevant diagrams and methodical steps strictly based on scientific facts. So children, grab this book as fast as you can to satisfy your scientific curiosities by performing these incredible experiments and learning science with fun. #v&spublishersContents:Introduction1.

Introduction
S cience, as we all know is a subject which is universal and knows no boundaries. It is also a pivotal subject in the school curricula of almost all the schools, across the globe. Hence, there is no need to explain the significance of science for students. It is invaluable and indispensable in today’s world.

However, science can never be taught theoretically. It always needs practical demostrations through simple experiments and projects as illustrated in this book. There are around 71 interesting experiments explaining the various simple scientific phenomena of gravity, temperature changes, air pressure, boiling, melting and freezing points of solids and liquids, magnetism, electricity, etc., all compiled together in easy language for the children to grasp quickly, and carry them out in schools and homes with adults’ or teachers’ supervision, of course.

The benefits of learning science through experiments are that children do not just understand the concepts but also implement them practically, clearing and testing their ideas independently. They are able to evaluate themselves and use their knowledge in future – not just confine themselves to classroom studies because Experimentation is a must in Scientific Studies to methodically verify, falsify or establish the validity and truth of an invention, theory or law.

Remember to always have fun with your science experiments and don’t worry if your experiments don’t come out as you would expect – some of the greatest scientific discoveries have been made by mistake.
Science is all around us in our daily living and the more you experiment with science and observe; the more fascinated you will become in finding answers.
Hence, go ahead, read the given fun-filled experiments and perform them at home or school with the help of your parents or teachers. Thus, you can also enjoy while you learn.
EXP-1
Make an Egg Float in Salt Water
A n egg sinks to the bottom if you drop it into a glass of ordinary drinking water. But what happens if you add salt? The results are very interesting and can teach you some facts about density.
What you need
One egg, Water, Salt, A tall drinking glass.

What to do
Pour water into the glass until it is about half full.
Stir in lots of salt (about 6 tablespoons).
Carefully pour in plain water until the glass is nearly full. (Be careful not to disturb or mix the salty water with the plain water.)
Gently lower the egg into the water and watch what happens.

What’s happening
Salt water is denser than ordinary tap water; the denser the liquid, the easier it is for an object to float in it. When you lower the egg into the liquid, it drops through the normal tap water until it reaches the salty water. At this point the water is dense enough for the egg to float. If you were careful when you added the tap water to the salt water, they would not have got mixed, enabling the egg to amazingly float in the middle of the glass.
EXP-2
Melting Chocolate
E njoy this simple melting chocolate experiment. You’ve no doubt experienced chocolate melting on a hot day, so let’s do some experiments to recreate these conditions as well as a few others before comparing results and coming to some conclusions. At what temperature does chocolate melt from a solid to a liquid? Is it different for white and dark chocolate? Give this fun science experiment a try and find out!
What you need
Small chocolate pieces of the same size (chocolate bar squares or chocolate chips are a good idea), Paper plates, Pen and paper to record your results.

What to do
Put one piece of chocolate on a paper plate and put it outside in the shade.
Record how long it took for the chocolate to melt, or if it wasn’t hot enough to melt then record how soft it
