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

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

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

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

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.

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

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

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 awesome science fair project idea, kids will be attempting to pick up different objects using snail slime.

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

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.

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

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

This science fair project idea investigates whether air has mass and weight.

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

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

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

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

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

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

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

Get a better understanding of water content by dehydrating carrots.

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.

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