This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

In this project children practice the scientific method while playing with puffy paint.

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 science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

This science experiment tests why guacamole goes brown and if leaving the pit in will stop guacamole from turning brown.

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

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

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

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

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

Find out whether we can create motion in a dish and as a result, create a wonderful and colorful show.

In this science fair project, young children discover what happens when two fluids that have different densities get together.

This science fair project teaches students about wilting and browning of salad greens.

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

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

This engaging project encourages young children to practice and refine the important scientific skills of sorting and classification.

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.

Using a toy race car kids create a visual model of the Doppler Effect.

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

This project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

In this project, create and examine garden mulch to find out what critters live in the messy, muddy layers just above the soil.

In this project children discover, identify, and sort seeds from a variety of fruits and vegetables

This simple project makes young children aware of their sense of smell and its capacity for providing them with information about their world.

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 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.
