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

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

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

In this fun experiment, learn about brand awareness and the influence of media on children by testing logo recognition in different age groups.

This project examines whether playing music during class helps students learn or if it distracts students from learning.

This science fair project idea researches the different layers of the atmosphere and creates a visual representation of the atmospheric layers.

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 science project encourages students to investigate the Mozart Effect, the idea that classical music promotes learning.

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 activity, children will work on their mathematics and engineering skills as they attempt to recreate the Eiffel Tower out of building blocks!

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.

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.

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?
