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

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.

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

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

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?

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

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.

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

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

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

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

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

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

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

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

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.

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

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

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

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.

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.

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

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

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

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

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