How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

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 trick uses vertical and horizontal forces to help your child to push apart your hands apart, no matter how hard you try to keep them together!

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.

Create a homemade pair of sunglasses with colored lenses to see just how light and color affect our sight! Use this fun project to practice science!

This surprisingly good glue recipe comes from common kitchen items.

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

In this 3rd grade science activity, you'll experiment with the little-known fourth state of matter: polymers! Mix borax with white glue and watch what happens.

This awesome diffraction grating experiment puts high school students' applied math skills to the test by having them calculate the wavelength of laser light.

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

This activity is a great introduction to polymer chemistry. It might seem complicated, but all you'll need is the material found inside of a baby's diaper!

Take this "paper plate snack test" with your child for a hands-on lesson in making healthier choices to teach your child about what's in his food.

This potato cannon activity teaches your middle schooler about the principle of Boyle's Law. Make a potato cannon and have a blast learning about science.

Wool can absorb 1/3 of its weight in water, while still keeping the body warm. She can test this theory by performing a scientific sock comparison!

Future whistleblowers can learn about product safety standards with this exercise in writing and researching.

Have your child build his own mini waterfall, and help him develop his planning, problem solving, and architectural skills.

When you see those sunscreen "protection levels," what does that really mean? Try this experiment to find out.

In this science experiment, your child will test the strength of hollow structures in order to understand how strong bird bones really are.

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.

Introduce your child to science with something they see everyday--their shadow!

This kids' activity is fun to perform and impressive to watch. Plus, it's a great example of Newton's First Law of Motion at work.
