Compare ability of selected materials to block UV-A radiation. Shine black light though glass at detecting beads underneath. Note color intensity.

Learn about magnifying glasses, concave lenses and inverted images by sending rays of light through a magnifying glass in this cool science fair project!

Science fair project that examines albedo, and how this information is applied in the design of cars, sportswear, and other items. Which colors reflect light?

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

This quick and simple preschool mirror activity will introduce your child to the science of reflection and light with a flashlight experiment and picture game.

You don't need to wait for rain to see a rainbow. Make one yourself, and teach your child about light and weather in the process.

This experiment evaluates if the lighting in a room affects the speed at which test subjects perform mental tasks.

In this science fair project, we'll explore how blocking the sun's light can stop those can stop photosensitive paper from changing color.

Believe it or not, images that are cast upon your eye's light-sensitive screen (called the retina) are upside down. Here's a fun, fast experiment to prove it!

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!

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 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.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

This science fair project idea focuses on the production of oxygen by plants during the photosynthesis process.

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 learn about the color rendering index by finding the best lightning for makeup in this fun and original physics science fair project idea.

Science fair project that demonstrates the process known as refraction, which allows glasses and contact lenses to help people with poor vision.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

Deck the halls with last season's Christmas lights for a spectacular and electrifying science activity.

What causes the seasons to change? Kids find out by modeling the earth's tilt using a globe, flashlight and graph paper in this cool science fair project idea.

Stir up some enthusiasm for experimentation with this candy-cracking science experiment!

Kids learn how fiber optics work with a dramatic total internal reflection experiment using a fish tank, water, and a laser pointer.

Scavenger Hunt! Check out this fun science fair project idea to explore the difference between opaque, translucent, and transparent objects around your house.

Do your laundry and your science project simultaneously! This science fair project investigates whether the color of a garment affects the time needed to dry.

Check out this cool science fair project idea on spectrum spinners and investigate how certain color combination can produce other colors.

How does a flashlight work? Kids will make a complete circuit and explore how voltage contributes to brightness with this science fair project idea.

Science fair project in which you will build your own algae photobioreactor which will meet the physiological requirements of algae for maximum growth.

Kids learn how to manipulate additive and subtractive colors to send secret messages with red colored filters in this cool science fair project idea.

What is a series circuit and how does it work? Learn about voltage, electrical current, and resistors in this cool science experiment!

What causes dilated pupils? Young scientists will find out by applying what they already know about changes in pupil size and making models of the pupil.
