Build a 3d animal cell model with this cool science fair project, which helps kids visualize and understand the function of a cell's parts and organelles.

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

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

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 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.

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.

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 fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.
