The best Expo projects are not always complicated, but imaginative and well executed A good Expo project is often:
The hypothesis is a tentative solution to a problem. The research activities are planned to verify the hypothesis and not to find out the solution of the problem or to seek an answer to a question.
It is very essential to a research worker to understand the meaning and nature of the hypothesis. This Tutorial explores how to write a hypothesis with best examples. Hypothesis In outline, an example research program might proceed as follows.
The preliminary investigation might lead to the hypothesis that a tree-based structure with poor memory locality will be slower in practice than an array-based structure with high locality, despite the additional computational cost.
The phenomenon that should be observed if the hypothesis is correct is a trend: The evidence is the number of caches misses for several sets of items to be sorted. And it is important to state what is not being proposed—what the limits on the conclusions will be. The exercise of refining and clarifying a hypothesis may expose that it is not worth pursuing.
For example, if complex restrictions must be imposed to make the hypothesis work, or if it is necessary to assume that problems that are currently insoluble must be addressed before the work can be used, how interesting is the research?
For example, some research consists of applying a black-box learning algorithm to new data, with the outcome that the results are an improvement on a baseline method.
A weakness of such research is that it provides no insights into the data or the black box, and has no implications for other investigations. In particular, such results rarely tell us whether the same behavior would occur if the same approach were applied to a different situation, or even to a new but similar data set.
That is, the results are not predictive. That is, we use experiments to learn about more general properties, a characteristic that is missing from black-box research. However, the hypothesis should not follow the experiments.
A hypothesis will often be based on observations, but can only be regarded as confirmed if it is able to make successful predictions.
Another perspective on this issue is that, as far as possible, tests should be blind. If an experiment and hypothesis have been fine-tuned on the data, it cannot be said that the experiment provides confirmation.
At best the experiment has provided observations on which the hypothesis is based. The research is given direction by the development of specific questions that the program aims to answer.
These questions are based on an understanding—an informal model, perhaps—of how something works, or interacts, or behaves. They establish a framework for making observations about the object being studied. This framework can be characterized as a statement of belief about how the object behaves—in other words, a hypothesis.
Astronomers use nuclear physics to predict the brightness of stars from their mass and chemical composition, for example, while a geneticist may seek to know whether substituting one gene for another can improve the health of a cell. Other hypotheses are constructive.
For example, we propose new technologies and explore their limitations and feasibility, or propose theorems that imply that there may be new solutions to long-standing algorithmic problems.
The scientist observes the man of a special class of phenomena and broads over it until by a flash of insight he perceives an order and intelligent harmony in it. The hypothesis furnishes the germinal basis of the whole investigation and remains to the end its cornerstone, for the whole research is directed to test it out by facts.
At the end, it comes to prominence as the proposition to be accepted or rejected in the light of the findings.Eskom Expo for Young Scientists is an exposition, or science fair, where students have a chance to show others their projects about their own scientific investigations.

How to Write a Testable Hypothesis. A comprehensive, coeducational Catholic High school Diocese of Wollongong - Albion Park Act Justly, love tenderly and walk humbly with your God Micah Step 2: Write the Methods. This section responds to the question of how the problem was studied. If your paper is proposing a new method, you need to include detailed information so a knowledgeable reader can reproduce the experiment.
How to write a Hypothesis. The first stages of a research program involve the choice of interesting topics or problems, and the identification of particular issues to investigate.
The research is given direction by the development of specific questions that the program aims to answer.
