Easy Science Fair Projects for Kids

The science fair is soon going to be organized at your school and students are busy finding out a good topic for their project work. Teachers are busy with the arrangement, making all possible efforts to guide their students. A few are nervous on how to go ahead with the work while rest have already started working on their topics. School goers can well imagine the situation and the activities that goes around just a few days before the exhibition. If you are falling short of ideas, then the following mentioned experiments would help you out.

Easy Ideas on Science Fair Projects for Kids

The Egg Experiment
At the elementary level, students are keen at performing experiments with eggs because it's one of the easiest thing to do. The two basic experiments performed with eggs are, finding out whether the egg is raw or boiled (without touching) and making an egg float in salt water. So how do you conduct these two experiments? To perform the first experiment, you need to keep a raw egg and a boiled egg side by side. Now spin both the eggs. You will find that the raw egg will wobble while the boiled egg will spin. You can draw an inference by explaining the scientific reason behind it. Raw eggs cannot spin because the white portion of the egg and the yolk present inside are set in motion, as a result of which the center of gravity changes and they start wobbling. While performing the salt water experiment with eggs, you will find out that eggs will float quickly in salt water because it's density is more than normal water. Thus, increasing the density of water makes objects float easily. You can set up this experiment model with a good presentation.

Growth of Plant in Presence of Earthworms
We all know that earthworms survive by eating soil and organic matter present in soil. Now this theory could be utilized for your science fair project with an artificial model of earthworms, soil and a few plant species. The logic that works behind it, is more important. Earthworms burrow in soil and their slow movements aerate the soil. They consume soil and organic matter which is digested and then excreted. Their excreta is deposited as castings which is rich in nutrients beneficial for growth of plants. If plants are grown in areas invaded by earthworms, they will have a better growth rate since nutrient concentration of the soil is increased by deposition of castings. Aeration caused in the soil is another factor that accentuates growth of plants. This way you can explain your experiment along with a short and precise demonstration of the biological phenomenon.

Electricity Project Works
Students having keen interest in physics can opt for electricity project works. One simple demonstration of production of electricity is the potato experiment. You need the following things to perform this experiment, viz, copper electrode, zinc electrode and a potato. Measure the voltage with an analog or digital multimeter. You will get these instruments in your physics lab. Stick both the electrodes in potato for sometime and then connect electrodes to the multimeter with the help of alligator clips. You will observe the reading on the multimeter due to production of electric current. Research more on such phenomenon and come up with new ideas to set up your own electricity project. Some other interesting topics include measuring the speed of electricity, finding out which is the best conductor of electricity and try various other regular methods for generating electricity.

Science fairs organized in schools offer creative freedom to students to bring out their scientific skills for creating a commendable work. I hope you got the concept of conducting experiments for a science fair or working on a project requiring good theory, explanation and presentation. Feel free to take necessary guidance from your teacher whenever needed. All the best!
