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

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

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

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

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

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

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

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

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

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 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.

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

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.

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

This science fair project idea teaches that time always passes at the same rate and nothing we do in our daily life âreallyâ affects how fast it moves.

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 children practice the scientific method while playing with puffy paint.

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

Kids will learn how to clean fish tank the natural way. Add catfish to the tank and see if your water gets cleaner.

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

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

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

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

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

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