High School Science Fair Projects

Choose The Right Science Fair Topics

All this while you have studied the different branches of science and at times performed one or two experiments in your school laboratories. In the science fair you will get the opportunity to use your own imagination and creativity.

At a higher level you are expected to prepare a project that will abound in originality and correct information. In an upper level competition the judges will test you on the basis of your knowledge in both general science and current science and technology. Your project should be relevant to contemporary uses of science and how it benefits society.

Before you do all that and prepare top quality high school science fair projects you should select a suitable topic. There are several branches of science from which you can choose a topic.

Life Science This branch of science covers a lot of topics primarily related to the biological world. For instance if you are doing a project on plants and bacterial growth you can follow these steps:

* Chalk out a comparison between gram-positive and gram-negative bacteria in terms of the effect of antibiotics on them. * Check the rate of toxicity in water or soil * Test the effect of ultraviolet radiation on bacteria growth. * You can experiment with plant hybrids or cross-breeding * Test the factors that affect the rate of transpiration in plants * Find out differences between organic and chemical fertilizers * Also test for harmful effects of pesticides

Physical Science Some of the basic common tests that you can carry out are:

* Effect of temperature on the refraction index of various liquids * Effect of storage temperatures on batteries * How you can use solar cells to recharge batteries * Compare the strength of different building materials with respect to how much they can bend * Test the extent to which stress and strain affect bridges * You can try out experiments with fire preventive building materials * Test the effects of magnets and electromagnetic fields on living organisms

Chemistry * Here you can perform experiments with the types, effectiveness, and the impact of nutritional value of preservatives in food * You can make a comparison of the properties and effects between sugar or any other natural sweetener and artificial sweeteners * How does the pH level of a solution affect the corrosion of iron and copper? * How can you prevent corrosion? * Try out different methods in which you can filtrate or purify water * Find out how enzymes and yeast cause fermentation

You can also prepare your high school science fair project on topics related to earth science and environmental science. As a student of high school you have to have a serious and higher approach to the function of science in the organic and inorganic world. When you prepare for your science fair project remember it is important that you enjoy your work and do not do it just for the sake of competition. Develop the spirit in you and watch out for the results!
