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?
Explain the 2 kinds of fogs, the advection and radiation. Advection fog forms from warm moist air blown inward. The radiation fog is the warm, moist air that forms too close to the ground. Create your own fog using two bottles with narrow necks. Fill 1 bottle with hot water and the other one with cold water then place an after several minutes place an ice cube on the mouth of each bottles. See what happens after.
How do fossils form?
Demonstrate how fossils form. You can make use of cardboard, plaster of Paris, leaver, water, and petroleum jelly. This method is to demonstrate how fossils form in mud. Mix the water and plaster of paris, spread the mixture on a cardboard. Cover the leaf with petroleum jelly and place it on the plaster. Allow it to dry then remove the leaf when the plaster dries, you now have a model for a fossil.
With these project ideas, you would surely impress the judges. Not only that, you can be proud of being a bonafide science kid.
