Discover that the absorbency of fabrics depend largely on the shape and structure of the individual fibers that make up the fabric.

This science fair project explores how osmotic pressure forces water through the root up into the plant.

Will the shape of an ice cube impact how fast the ice melts?

Examine the effect of pressure on carbonation in soda.

This science fair project idea explores how the shape of a boat affects its density and how much weight it can float.

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

This science fair project idea provides evidence that air is everywhere and takes up space.

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

Find out whether cast iron or regular teflon pans heat up faster and also retain their heat longer.

The objective of this science fair project is to set up a compost bin to convert food scraps and organic waste.

Discover whether the â5-second ruleâ is effective at determining whether food is still safe to eat after being dropped on the ground.

This fun science project helps to investigate how much water can a plant take up and release in a certain period of time through the process of transpiration.

What heats up fasterâwater or soil? 5th grade students test the specific heat of water against the specific heat of sand in this great science fair project.

Soil is made up of different layers. How far down do you need to dig to find the soil horizon, or the place where bits of leaves and branches become soil?

This science fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.

Discover whether a metal will expand under hot water.
