Is it a square or a circle? See if you can trick your friends with this zany science project!

Discover that the absorbency of fabrics depend largely on the shape and structure of the individual fibers that make up the fabric.

This science fair project explores how osmotic pressure forces water through the root up into the plant.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

In this project, a model of a submarine is built to simulate the buoyancy and displacement of water and air.

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

Examine the effect of pressure on carbonation in soda.

This science fair project idea explores how the shape of a boat affects its density and how much weight it can float.

This science project teaches students to classify different shapes of leaves.

Make water and clay play a little more scientific with this hands-on experiment that teaches displacement and shows how an object's shape affects its buoyancy.

This kinesthetic learning activity will help your fourth grader get a firm grasp on the immensity of the solar system.

In this activity, your student will be invited to build a chair out of building blocks that is designed to meet the specific size and shape of a small doll or toy figure.

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

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

Stir up some enthusiasm for experimentation with this candy-cracking science experiment!
