Science fair project idea that examines different physical characteristics of a chosen animal. Make educated guesses about evolution based on animal's form.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

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

Here's a fun activity to help build thinking skills in young first grade scientists, and to encourage them to have a blast exploring the mass and volume.

Engineers in training can get started with this simple wheel-and-axle construction activity.

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

By incorporating natural materials and the powers of observation, your child will become a backyard naturalist while building early writing and drawing skills!

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

Here's a classic celery science experiment that uses celery and food coloring to demonstrate how plants absorb water.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

This project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.

If you're looking for something to keep your kid busy on a warm day, and give him some writing practice in the process, bring on the mud!

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

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

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

Put a twist on traditional oil painting with this fun science activity that you and your first grader can do together.

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

Challenge your young dinosaur lover to examine dinosaur footprints and then create their own dinosaur fossil in this hands-on activity.

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 is a fun way to introduce kids to the concept of volume, and give them a quick hands-on activity to boot.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

What's cooler than an explosion? Not much! This simple science experiment lets kids build their own pop rocket. So put on your safety goggles and let her rip.

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

Uh-oh! Is that a pill sitting on the counter or a piece of candy?

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

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

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.
