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

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

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

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

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.

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 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.

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

Get ready for a yummy taste test! Just pour the milk -- and make sure you have some chocolate chip cookies on hand.

Learn how different types of soil affect how animal tracks form in this experiment!

This classic children's game demonstrates how sound travels through air vs. through a solid.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

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

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

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

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.

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

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

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.

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

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.

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

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.

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

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