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

In this project children practice the scientific method while playing with puffy paint.

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

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

Children will learn all about cause and effect as they experiment with potion-making in this Halloween themed activity.

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

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

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

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

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

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.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot navigate around several obstacles.

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

This science fair project idea teaches that time always passes at the same rate and nothing we do in our daily life âreallyâ affects how fast it moves.

Kids often ask, "how tall am I?" This science fair project seeks to determine how well kids can guess their own heights.

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

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.
