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

This super fun science project, perfect for young children, combines crafts, dressing up as animals, outdoor play, and life science learning.

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

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

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

This project makes young children uniquely aware of their sense of touch and its ability to alone give them information about the world around them.

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

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

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

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

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

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

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

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

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

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.

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.

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

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

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.

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?
