Science Experiments

Science Experiments

A science experiment is one which exposes the use of the scientific method to look into a scientific observable facts, phenomenon, principles, developments or laboratory process. It is instigated from the school level itself so that students not only learn the hypothetical but practical aspects of the subject as well. Science Experiments is also carried out for the scientific and technological in the national for the technical advancement and scientific development of the nation.


Scientific Method and Hypothesis:

Science experiments are based on scientific method and hypothesis of the experiments. Scientific method involves the process and the steps of the experiment being conducted. The premises and laws which one justifies or proves by following the scientific method and carrying out a science experiment is what known as hypothesis. Scientific method and hypothesis concluding element of all the scientific experiments.

Elementary Science Experiments:

Science experiments which are instigated at school level are elementary in nature. They include simple to conduct and easy to understand and comprehend. This is so because they are conducted by kids and school going children. Some of the science experiments require laboratory support while some of them can easily be conducted in home. Science Expriments aims to initiate the curiosity in a student that why things happen in a particular way.

The essential characteristics of elementary science experiments is the nature of the scientific method involved in the experiments are simple. Its scientific method is nothing but actually a simple and systematic organization of procedure and steps involved in the experiment being performed for the ease of students.

Advanced Science Experiments:

Science experiments which are performed at national laboratory by the scientists of the country for the purpose of scientific growth and development of the nation are advanced science experiments. Hypothesis of such science experiments are not defined previously but they are formulated after the successful execution of the experiment being conducted. High end scientific method is used in advanced science experiments and generally a heavy expenditure of money is involved in it.

Examples of Elementary Science Experiments:

Electro Magnetism

The aim of this experiment is to make it clear how the flow of electricity can be converted and used as a magnet. The concept is known electro magnetism. The basic idea behind an electromagnet is really uncomplicated: By running electric current through a wire, you can generate a magnetic field. Under this experiment, an iron rod is draped with insulated copper wire and the two ends of the wire are connected to a power battery. As soon as the current flows from the battery to the rod, it turns into a magnet and carries all the physical features of a magnet.

Air: Physical Property of Weight

This experiment aims at proving that air, which is often regarded as an abstract and weight less element has a weight. Under this experiment, a balance is prepared by the help of two sticks. One stick is fixed to other in the shape of English alphabet ‘T to create a balance. On one end of the balance, an empty balloon is attached and on the other end an air filled balloon is attached. One can easily observe in the experiment that the balance is tilted towards the air filled balloon. This proves that air has its own weight.

Creating Volcano:

A virtual volcano can be created by the help of clay. Under this experiment, first of all a volcano like structure is modeled out with clay or plaster of Paris. For the illustration of eruption, a chemical process is used. Under this process, a tablespoon of baking soda is added with a few drops of dish washing detergent. Then ¼ cup of vinegar is added for the chemical reaction to execute. Red coloring can be added for providing real like effects to eruption. The eruption is acid reacting with another substance called an alkali.

Concept of Static Electricity:

The concept of static electricity can be explained by the help of this experiment. Under this experiment, a hard plastic comb or a ruler is rubbed against a fur or nylon and it gains some electrons due to this procedure and is negatively charged up. Now it can attract small tit bits of paper or cereal. When a cereal or a paper is attracted, it has no charge or is neutral but as soon as it comes into contact with the charged up comb, it gains some electrons from it and when both comb and paper are equally charged up, they repel each other and the paper or cereal falls off.
