Kindergarten Science Fair Project Ideas

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

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.

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

In this experiment, students will create their own version of coquina, a sedimentary rock thatâs formed by seashells and sand, cemented by seawater minerals.

In this science project, young children observe, record, and create collections of colors in their world and increase their powers of observation.

In this science fair project, young children observe, record, and create collections of shapes in their world and increase their powers of observation.

In this science fair project, young children notice and track changes in trees throughout the year.

In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

In this project combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.

This play-activity causes young children to focus on and become more aware of their sense of hearing and the power of their ears.

In this science fair project, we'll explore how blocking the sun's light can stop those can stop photosensitive paper from changing color.
