Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

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

In this exciting design challenge, your child will use design thinking skills to create a mixture that can inflate a balloon.

What's the chemistry behind dyeing Easter eggs? Will adding vinegar to dye help the eggshell absorb the color? This colorful science project has the answers!

What causes sound? Here's a simple science experiment that adds a visual element to the science of sound to help kids better understand this tricky concept.

This science fair project idea explores the different properties of matter.

This simple heat transfer experiment is a great introduction to the concepts of heat transfer and conduction.

Do you think you can blow down a sand castle with a mighty wind? Find out which material stands up best to erosion in this erosion experiment.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

Kids learn how to prevent erosion by growing grass. They'll test soil with grass against raw soil in this revealing science fair project idea for 4th grade.

What are buttress roots? In this fun science project, make a model of a rainforest tree and learn how they help trees survive in the tropical rainforest!

Learners hypothesize about and experiment with soil erosion in this hands-on activity.

This science fair project on testing water hardness is a great introduction to practical chemistry. Test and learn the difference between hard and soft water.

Gymnosperms are coniferous trees that reproduces using pine cones to spread seeds. Check out this simple pine cone experiment to learn about the process!

In this activity, students will create a stop motion animation by creating a clay figure and taking a series of digital photographs.

Use simple items to create a kindergarten "grow box" that lets a kid see just how salad plants send down their roots and grow underground.

Kids discover what a homogeneous mixture is by adding sugar to distilled water and identify the various factors affecting solubility.

This science fair project idea demonstrates that light travels in straight lines and experiments with reflecting light.

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

In this experiment you observe and determine how well your cat uses his whiskers to navigate through a maze.

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

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

Ever wondered how a plant drinks water? This science project will teach you how and help you create a beautiful floral display!

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

Here's a fourth grade science craft with lots of benefits: it's good for birds, good for your child's learning, and good for the planet, too.

Teach your child how butter is created by shaking up cream the old-fashioned way.

Here's a classic celery science experiment that uses celery and food coloring to demonstrate how plants absorb water.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.
