Easy Science Fair Projects for High School

When you reach high school, you are expected to gain considerable hands on experience for carrying out practical works. Science fairs conducted by schools or a project work assigned to students is a medium through which they can exhibit their scientific endeavor at the maximum. Students should catch up those topics in which they are most interested and then come up with an idea that will be appreciated by everyone. Easy science fair topics for high school are associated with simple techniques that yield high results and are quite absorbing at the same time. For your assistance a few good ideas are elaborated in the next segment.

Easy Science Project Topics for High School Students

Measurement of Bacterial Growth
You can perform a bacterial assay by culturing a microorganism in a growth medium. Usually E.coli is used as a specimen. For performing this experiment you can keep temperature as constant and then culture the bacteria on different agar plates. The experiment could also be performed in many ways, viz, using streak dilution method and culture plates method. Now observe the growth of bacteria after 12, 24 and 36 hours. You can measure the growth with the help of an U.V spectrophotometer or a colorimeter. Note down the growth rates and draw a graph from it. If the experiment has been conducted without any contamination then you will get distinct phases of growth, I.e lag, exponential, stationary and death phase. This experiment is quite interesting and has to performed very carefully under a sterile environment.

Titration Experiment
This is one of the most common topics for high school science fair projects. Titration is done for qualitative and quantitative analysis of acids and bases. While performing quantitative analysis the molarity of the unknown acid solution is determined by measuring the value at which color change of the solution takes place. The experiment is performed with the help of a base that aids in neutralization of pH and thereby, computing the exact molarity of the unknown acid. The equipment consists of a burette, beaker and a clamp for holding the burette. Students usually find out the molarity of the unknown acid by using a known quantity of Sodium Hydroxide solution. While performing qualitative analysis, the acid dissociation constant of different acids are determined with the help of a base for performing titration. You can also try out back titration and redox titration.

Prism Experiment
Performing different kinds of experiments with the help of a prism is very absorbing for students. They not only find it interesting but they derive immense pleasure observing light passing through a prism. You can perform some experiments with the help of a prism like refraction and formation of rainbow and spectrum. When light passes through a prism, it splits into seven different colors since its composed of different wavelengths having different speeds. Demonstrating this nature of light with a clear explanation is a wonderful idea. Refraction experiments are performed with the prism and paper while detecting the spectrum of light could be done with the help of an external light source and a diffraction grating prism.
