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

Who needs paint, glitter, or crayons when you have natural art supplies right outside your front door?

Ever wonder why refrigerator lights turn off when you close the door? Does the darkness prevent food from spoiling? This experiment, determines just that.

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

In this science fair project, young children observe, record, and create collections of shapes in their world and increase their powers of observation.

If your child aspires to be the next Frank Lloyd Wright, we've got some tips on building sand castles that last.

Put those fall leaves to use with this fun art activity. Kids paint and print leaves, to make a beautiful tablecloth, perfect for your next fall celebration.

It's a rare kid who doesn't like a sandbox. Next time you're out digging, build in some earth science, too.

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

On the next chilly, winter day, invite your fifth grader to make a hand warmer by experimenting with the loaded combination of a few natural ingredients.

The next time you and your fifth grader go on a hike, take along this key to figure out which common North American animal left a track along the river bank.

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