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

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

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

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?

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.

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

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

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

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

Get a better understanding of water content by dehydrating carrots.

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

In this science fair project, we'll explore how blocking the sun's light can stop those can stop photosensitive paper from changing color.

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

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

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.

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

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

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

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

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

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

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

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

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