A science fair is a great platform for school kids to apply their theoretical knowledge to practical use. The otherwise boring science concepts, when explained through science experiments suddenly become very interesting. Needless to say, kids actively participate in science fairs and hope to bag an award for their project. The preparation for science fair projects begins months before the event. So, in case you too are busy looking for topics or projects for science fair, then this article should be able to provide you with some cool ideas.
Winning Science Fair Project Ideas
One important tip for winning science fair projects is that one needs to understand the concept thoroughly. Many a time students take a complicated topic and present a complex experiment without understanding it. As a result, they often falter when the question answer round comes. On the other hand, kids who take a simple concept and master it have an edge over other kids. A simple concept can be understood thoroughly, hence explaining the experiment also becomes easier. Hence, while choosing a topic for your science fair project, make sure you understand the matter thoroughly.
Capillary Action of Soil
You will need three types of soil; clay, sand and loam for this experiment. Take three tall glass tubes and plug one of their ends with glass wool. Fill each of these tubes with sand, clay and loam. Take a large vessel containing water and immerse the tubes vertically in it. The capillary action of the soil causes the water to rise upward in the tube. Measure the water level in each of the tubes after a few days and find out which of the three soils shows the maximum capillary action.
This experiment allows you to purify water using several mechanisms. The assembly includes a glass beaker, filter paper, funnel, glass tube, filter stand etc. Take some muddy water in a beaker and let it settle for some time. Attach the funnel to the filter stand and place a beaker to collect filtered water from the end of funnel. Fold the filter paper in four folds and place it inside the funnel. Pour muddy water through the glass tube in the funnel, without disturbing it. Collect the water in the second beaker and pour it into two identical glass jars. Treat water in the first jar with alum and leave the jars undisturbed for a couple of hours. Observe the clarity of water in the two beakers and note your observations.
Effect of Music
This behavioral science experiment allows you to study the effect of different music genres on the human mind. Conduct your survey in a kindergarten or a day care center. Play different genres of music and study how kids respond to each of these genres. Also, study the correlation between music and sleep pattern of kids. Note your observations.
Growth of Fungus
Do you want to check how many microorganisms are present on your body? Take a cotton swab and collect a sample from between your toes. Put the swab in a petri dish and allow it to grow in isolation. Check the growth after a few days. You can collect the sample from various areas such as mouth, your pet's mouth etc.
There is really no dearth of good science fair project ideas and topics. You can indeed repeat award-winning science fair projects from previous years, however, make sure to represent it in an innovative way. Most importantly, understand the concept thoroughly so that you are well prepared for any question.
