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.

What is topography? Kids find out by learning to make and read a topographic map in this awesome science fair project idea.

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

What's the best way to make DIY compost? Kids will learn about aerobic and anaerobic decomposition while learning to appreciate the value of composting.

Students will investigate the thermal conductivity of metals by learning how to measure thermal conductivity with this fun and easy science fair project idea.

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.

Use this fun activity to make an optical illusion picture that helps your kindergartener explore the sense of sight, and sharpen his observation skills!

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

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

Throughout history, people have used song as a teaching and memory tool. This project explores whether song improves a person's ability to retain information.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

Checkerboard play challenges students to use spatial reasoning and computational thinking.

Blend art and science in this hands-on activity that shows your kindergartener how primary colors combine to make secondary colors.

Are your taste buds up for the challenge? Put tongues to the test with this science fair project that examines who enjoys sour flavors more, adults or kids?

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

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.

The purpose of this study is to determine if people can tell the difference between organic and conventional food from looking at, smelling and tasting it.

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.
