Introduce your child to the world of motion and physics with a bit of marble play inspired by Sir Isaac Newton!

In this science and engineering activity, children will explore types of tunnels and their purposes and then design and build a tunnel of their own.

Develop your child's mathematical and engineering skills with this fun building brick challenge. In this activity, your learner will be challenged to create a boat out of building bricks.

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.

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

How do we know that air exists when we can't see it, taste it, or touch it? Here's a classic experiment that will teach your kid some basics of aerodynamics!

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

In this science fair project, young children discover what happens when two fluids that have different densities get together.

This activity is a fun challenge for students who have just started learning to program educational robots.

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

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

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.

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.

In this activity, students will be challenged to describe and count the ways a toy moves from one position on a grid to another.

This science fair project idea investigates if webbed feet help a duck (and others) swim.

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

Can you dig it? This science experiment isn't for kids who like to keep their hands clean.

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

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.
