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.

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

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.

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

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

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

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

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

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.

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?

Dinosaurs were huge creatures that left behind huge footprints that lasted for millions of years. In this science fair project, kids learn how dinosaur tracks were left behind!

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

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

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

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

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 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 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.

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

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

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