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 experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.

The goal of this science fair experiment is to demonstrate the effects of air pressure on objects and analyze applications of air pressure principles.

Here's a household scavenger hunt that shows kids the natural sources behind everyday objects...and builds reading skills, too!

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

Delight your budding scientist with this cool physics magic trick and teach her some basic physics concepts while you're at it!

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

In this hands-on activity, kids learn what it takes to foster seedlings into full-grown plants, all in a regular old soda bottle!

Get your sense of humor ready for this fun science experiment that demonstrates the fundamental physics of air pressure.

Teach your first grade scientist the difference between liquids and solids using maple syrup.

Alive or not? This yeast experiment you can conduct with your little scientist explores the answer to this timeless question.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

Here's a science activity that lets a first grader use an empty dish detergent bottle to create his own fountain as he explores air pressure.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

Kids construct a single fixed pulley system to learn how pulleys can make work easier in this cool physics and engineering science fair project idea.

Build a bird feeder science craft that brings birds to your yard, and a smile to the whole family's face.

Introduce your child to the importance of preserving the world's biodiversity by turning a lesson on endangered species into a fun game for the whole family.

In this simple and social activity, children use size comparison skills to find objects in nature that are bigger, smaller, longer, and shorter.

This science fair project idea explores substances that cause a bubble to last longer.

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

Help kids tap into their inner inventor by teaching them how to make peanut butter through trial, error, and lots of taste testing!

Introduce your child to the world of motion and physics with a bit of marble play inspired by Sir Isaac Newton!

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

How does salinity affect the point at which water freezes? Kids will find out by performing this cool melting ice experiment.

This activity works well with a group or just with a parent and child, and it can make a great party game since it's both fun and inexpensive.

Encourage your kindergartener to investigate and chronicle the weather she observes during the coldest months of the year.

In this outdoor science activity you'll find tips on how to create a nature journal by choosing a native plant or animal and tracking that species.

In this project students experiment with making music using only glasses of water.
