A science fair experiment is generally a competition where contestants present their science project, results in the form of a report, display board, and/or models that they have created. Science fairs allow students in elementary, middle and high schools to compete in science and/or technology activities.The main motive of a science fair is for students to answer a question or task, not from a textbook but found out themselves by conducting a range of experiments and ongoing research in the short amount of time allocated to them. In order that the questions or tasks spark a true interest in the student they should be able to have an interesting, eye catching project often portrayed on a display board.

Science fairs also provide a mechanism for students with intense interest in the sciences to be paired with mentors from nearby colleges and universities, so that they can access to instruction and equipment that the local schools can.

Science Fair History
Science fairs date back to 1942, when William Emerson Ritter and Edward W. Scripps created "The Science Talent Search" for high school students. The first American National Science Fair was won by Alan J. Fletcher when he was 18, winning with a display on the laws of motion. In the United States, science fairs became popular in the early 1950s. Interest in the sciences was at a new high after the world witnessed the use of the first two atomic weapons and the dawn of television. As the decade progressed, science stories in the news, such as Jonas Salk's vaccine for polio and the launch of Sputnik, brought science fiction to reality and attracted increasing numbers of students to fairs.

Science fair competitions
Most countries have regional science fairs in which interested students can freely participate. Winners of these regional fairs send students to national fairs such as ISEF and CWSF. National science fairs typically send winners to international fairs such as ISEF (which is a national and an international science fair) and EUCYS.

C.S. Sudheer, founder, indianmoney.com, said mutual funds are a professionally managed trusts, where money invested by you and other investors are pooled and invested in stocks, debt or a mix of stocks and debt, depending on the type of mutual fund. SIPs are just a method of investing in mutual funds and to understand better, one should know these difference between mutual fund and SIPs. It is a smart and hassle-free method of investing in mutual funds. Through SIP you can invest a certain, fixed, pre-determined amount at regular intervals of time like once a week, month or quarter. Doing so, SIPs give you the twin major benefits of rupee cost averaging and the compounding benefit.

At present, life insurance enjoys maximum scope because the life is the most important property of an individual.
Each and every person requires the insurance.
This insurance provides protection to the family at the premature death or gives an adequate amount at the old age when earning capacities are reduced.
Under personal insurance, a payment is made at the accident.

An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments vary greatly in goal and scale, but always rely on repeatable procedure and logical analysis of the results. There also exists natural experimental studies.

Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time.Experiments can vary from personal and informal natural comparisons (e.g. tasting a range of chocolates to find a favorite), to highly controlled (e.g. tests requiring complex apparatus overseen by many scientists that hope to discover information about subatomic particles). Uses of experiments vary considerably between the natural and human sciences.

Experiments typically include controls, which are designed to minimize the effects of variables other than the single independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements. Scientific controls are a part of the scientific method. Ideally, all variables in an experiment are controlled (accounted for by the control measurements) and none are uncontrolled. In such an experiment, if all controls work as expected, it is possible to conclude that the experiment works as intended, and that results are due to the effect of the tested variable.
