The objective of this science project was to build a model of a volcano and observe reaction between different substances, including baking soda and vinegar.

What's the science behind those out-of-sight roots? Find out if you can trick roots into growing in different directions.

The objective of this science project is to determine the length of time for different seeds to germinate.

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 science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

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.

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

In this science fair project, students use the streak test to tell minerals apart from each other.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?

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

This science fair project idea investigates emulsifiers that allow oil and vinegar to mix.

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 fair project idea investigates how the shape of an object affects drag.

This science fair project idea investigates if webbed feet help a duck (and others) swim.

This science fair project idea investigates which objects float and sink in honey, water, and oil.

Learn about the layers of the Earth and make a model! Create a earth layer book, cake, or clay diagram.

Do earthworms like moisture or darkness? Find out as we explore the relationship between earthworms and light.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

This science fair project idea explores how length affects the weight a bridge can hold.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

In this project, build an insect model that shows how the head, thorax, and abdomen fit together! Learn insect anatomy by constructing a paper mache critter.

In this science fair project, kids measure how weather conditions affect how fast a puddle evaporates.

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

Do you think you can blow down a sand castle with a mighty wind? Find out which material stands up best to erosion in this erosion experiment.

This science fair project idea investigates how optical distances change the apparent size of an object as seen through a magnifying lens.

This science fair project idea investigates if fats add to the flavor of food.

Can you dig it? This science experiment isn't for kids who like to keep their hands clean.

Is it possible to trick the forces of nature that make your bubbles round to create a square bubble?

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

When you cut a flower to put into a vase, it'll eventually wilt, even with water and sunshine. But is there another scientific secret to keeping flowers fresh?
