Easy Science Project Ideas for Kindergartners – Science Fair Ideas

Science projects are a great way to get kids to develop an undying interest in science and natural happenings around them. Learning a subject hands-on is an experience that kids will cherish when they grow up. Some of the science project ideas illustrated below will help kids set up their independent stalls at the next science fair and demonstrate their science project with immense pride!

Science project ideas for kids

Floating egg – This is an easy science project that the little kids can take up in their next science fair. Stir in lots of salt in a glass of water and slowly slide an egg into it. Notice how the egg floats and doesn’t sink. Explain the theory of buoyancy and density in very simple words to the kids so that they can narrate it to their audience at the fair.

Mixing water and oil – Add a few drops of color to half a pan of water and pour it into an empty soft drink bottle. Add an equal portion of oil and ask kids to mix it thoroughly. A few seconds later, you will notice the oil floating back to the top. With minimum mess and little involvement from the adults, this science project is sure to excite the little ones! Though water is a highly soluble liquid, it refuses to mix with oil because the latter’s molecules are more attracted to each other making it denser and causing it to float above the water.

Making Coquina – Moisten a cup of pasta shells. Make sure that you use at least 3 different kinds of pasta. Mix them with white glue and spread them on butter paper to dry and become rocky. There you go! Your kids have their very own homemade coquina! Exhibit these at your kid’s next science fair and watch him thoroughly enjoy the learning process!

Jumping coins – Fill a bowl with cold water. Place the bottle neck and coin into the bowl of water to chill them. Place the coin at the mouth of the bottle. Wrap your hands around the bottle and wait for a few seconds. The air inside the bottle heats up when you hold it tight with your hands. The warm air pushes harder than the cool air outside the bottle which forces the coin to jump up.

Super-saturation of a liquid – This is a science project that your kids would not mind tasting! Dissolve sugar cubes in a glass of cold water. Make sure that you count the number of sugar cubes that you put in. Mix until the cubes do not dissolve further and start settling at the bottom. Repeat the same process with a glass of hot water. Count how many sugar cubes it takes to dissolve completely in the hot water. Explain to kids that dissolving sugar or any other solvent in water depends upon water’s super saturation level.  However, hot water dissolves more sugar cubes because it has faster moving molecules which are spread further apart. With bigger gaps between the molecules in the hot water, more sugar molecules can fit in between.

Make your kindergartner’s next science fair project a memorable one with these simple and easy science project ideas!
