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

Kids often ask, "how tall am I?" This science fair project seeks to determine how well kids can guess their own heights.

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

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.

Slime: It's oozy, it's goopy, and it's just plain fun! Learn how to make slime with this fun science fair project.

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

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

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

In this project, a basketball containing different psi is dropped to see how well it bounces.

Learn how to be a bird scientist in this simple project of watching feathered friends in their habitat.

Plants need water to grow. In this project we learn how plants transport water from their roots to their leaves

This science fair project idea demonstrates how air resistance contributes to denser objects falling faster than less dense objects.

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

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

Learn how starch and carbohydrates interact with different solvents in this fun and easy packing peanut science fair project.

What is surface tension? Kids will discover how water-skating insects use surface tension to keep from sinking by making a model water walker.

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.

Why does purple cheese look nasty? Because color plays a big part in how we perceive the taste of different foods. Are birds just like us in this respect?

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

Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

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

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

This science experiment has students test whether a snail moves faster on concrete or dirt.

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

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

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

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

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

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.
