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.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

Show your child how to concoct a simple duo of household ingredients that changes color as acids and bases are added!

Find out whether optical mice are useful on all surfaces or if there are drawbacks to this supposedly superior solution to the traditional roller-ball mouse.

In this activity, your kid will watch coal turn into crystals right before her very eyes, and learn some science along the way!

This science fair project idea studies which kind of rock (sedimentary, igneous, or metamorphic) is most damaged by frozen water.

This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

This experiment uses a yeast solution, liquid detergent, and hydrogen peroxide to produce an exciting reaction like no other!

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

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

This science fair project idea investigates how color affects temperature.

This science fair project idea discovers which brand of bubblegum produces the largest bubbles.

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

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

What is the hydrologic cycle and how does it work? Check out this fun and easy science project where you will model and learn about Earth's water cycle!

Examine whether distilled water, spring water, or regular tap water yield faster plant growth.

This science fair project idea discovers if an artificial light source will yield the same plant health and growth rates as light from the sun.

The objective of this science fair project is to test the growth rate of a plan in a crystal medium in comparison to traditional soil.

What happens when colored beams of light mix? You might be surprised.

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.
