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

Discover that the absorbency of fabrics depend largely on the shape and structure of the individual fibers that make up the fabric.

Understanding absorption means understanding why certain fibers and materials can absorb water! Kids will see absorption in action in this simple project.

In this cool physics experiment, use double plane mirrors at various angles to learn about light reflection. Then, see if you can solve a puzzling problem!

This science fair project idea explores which fruit molds the fastest.

When you cut a flower to put into a vase, it'll eventually wilt, even with water and sunshine. But is there another scientific secret to keeping flowers fresh?

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

Explore the craters, maria, and highlands on the surface of the Moon! In this fun science project you'll create a 3-D model of the moon using paper mache.

Would it hurt to skip brushing your teeth just this once? Let's find out by seeing which foods produce the most mouth bacteria.

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

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

Kids will create their own version of Richard Feynman's rubber band heat engine to learn about thermodynamics with this cool science fair project idea.

The moon doesn't produce its own light, so why can we see it shining in the sky? Learn about reflection and planetshine in this fun and easy science project!

Demonstrate how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.

This science fair project idea investigates the hardness property of minerals.

This science project teaches young students about germs, bacteria, and the importance of washing their hands. Students will test what is the best way to wash.

Slime: It's oozy, it's goopy, and it's just plain fun! Learn how to make slime with this fun science fair project.

In this CD hovercraft science project, students will construct their own DIY hovercraft.

Crayons aren't just good for creating colorful masterpieces -- they're also great for science!

Use chemical analysis to identify a variety of mystery powders that look the same but actually have very different properties.

Kids make a paperclip perform an act of magnetic levitation and test how effective various materials are at magnetic shielding in this science fair project.

This science fair project idea determines the most effective method of preserving food.

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?

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