Cool Science Fair Project Ideas For Elementary Students

Awesome science project ideas for elementary kids include: Do ants produce acid when angered?, How much percentage of an orange is water?, How do fossils form?, How do fogs form?

Finding the right science project usually requires much deliberation. But, you don’t really need a complex project to impress the judges. Here are some simple but cool science fair ideas for elementary students.

Do ants produce acid when angered?

The purpose of this experiment is to determine when insects like ants spray formic acid when angered. Get a few pieces of cabbage, then boil it for at least 15 minutes. Drain the leaves over a glass afterwards. Cut a paper towel into few strips, then dip the strips into the drained cabbage water. Spread out each strip and allow to dry. Afterwards, place the strips over the ants. Note the changes of color, when the strips turn pink, the ants secreted acid, when it’s green, it’s a base.

How much percentage of an orange is water?

This experiment aims to determine how much water is present in an orange. First step is to weigh the orange. Also weigh the aluminum foil used to place an orange on. Cut the orange into very thin slices. Place the orange on the aluminum foil. Allow the orange to dry in a warm place, you may use a desk lamp to speed up the drying process. The completion of the drying process can take about 4 to 36 hours. Once fully dried, weigh again the oranges. Subtract the weight of the dried orange from the fresh one, then do your conclusion.

How do fogs form?


How do fossils form?


With these project ideas, you would surely impress the judges. Not only that, you can be proud of being a bonafide science kid.
