Discovering the Best Water for Plants

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?

Pasta Coquina: Make Your Own Sedimentary Rock

In this experiment, students will create their own version of coquina, a sedimentary rock thatÃ¢s formed by seashells and sand, cemented by seawater minerals.

How Does Pressure Change Minerals?

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.

Glove In a Jar: Demonstration of a Closed System

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

Air Pressure Science Experiment: Balloon and a Jar

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.

How Well Does Sound Travel Through a Gas? A Liquid? A Solid?

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.

Animal Tracks and Types of Soil

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

Using Garden Mulch to Make a Bug Zoo

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

Why Do Plants Wilt?

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

Do Some Liquids Expand More than Others When Frozen?

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.

Exploring Static Electricity with Sticky Balloons

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

Plants Need Sunlight and Water

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

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

Whole and Parts: Taking Things Apart

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.

Eureka! Volume and the Displacement of Water

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

What Happens When Oil and Water Get Together?

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

How Sound Travels Through Air and Solids

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

The Speed of Sound on a String

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

Density Experiment

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

Leaf Rubbings: Shapes and Patterns

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

Hide and Go Listen: A Hearing Activity

This play-activity causes young children to focus on and become more aware of their sense of hearing and the power of their ears.

Sun Print: How Solar Energy Creates Chemical Changes

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