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.

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 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.

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.

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 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.

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.

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.

In this activity, students will think about the form and function of household objects as they compare and contrast kitchen serving spoons of various sizes and designs.

This science fair project idea investigates if fats add to the flavor of food.

This project determines what category of person is most likely to be ticklish.

This easy aerodynamics activity is a simple way to introduce kids to the scientific method.

Challenge your learner to design and build a city of their own in this creative engineering activity.

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.
