Use applied math to model orbital eccentricity in this cool science fair project for 7th grade.

Give your child a chance to experiment with how things grow. And throw in something extra to up the fun factor even more...her very own grass pet!

The objective of this project is to examine the ways in which a passive solar house may contribute to conservation of energy.

Test products which claim to reduce wrinkles, and determine which is the most effective. Test effectiveness over three weeks, using a sample of volunteers.

Try this simple 2nd grade science experiment to teach your child about the principles of luminosity and light reflection.

Bring the magic and mystery of the night sky to the light of day with this fun constellation art project!

Measure the effectiveness of detergent containing a UV-absorbing compound in blocking UV-A radiation. Use black light and UV detecting beads.

We all know that the Moon has different phases, but it can be hard to figure out why. Try this activity to see how the Moon's phases really work.

The objective of this science project is to determine the relationship between carbon dioxide gas and the temperature of the atmosphere.

The objective of this project is to evaluate whether a top will spin at different rates during different phases of the moon.

This science fair project idea teaches how the gases and pollution in the air affect the earth's atmosphere temperature.

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?

In this fun experiment, we'll find out how color affects heat absorption!

How does distance affect the spreading of light? Kids see diffraction and the inverse square law of light in action with this great science fair project idea.

Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.

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

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.

Kids will make a beautiful rainbow in a jar and learn what enables different types of liquids to remain distinct in separate layers.

In this science fair project, students determine whether a bean plant grows faster and taller using a traditional soil planting method or hydroponic method.

In this math and science activity, help your middleschooler learn about proportion and measurement with just her shadow and a tape measure!

This experiment will explore how manipulating a graph of historical information might reveal new information about data.

This science fair project will help students learn about non-vascular plants, such as mosses.

Science fair project that evaluates how well clothing fabrics block UV radiation by examining the properties of different fabrics.

Science fair project that explains and demonstrates the parallax principle.

Bake some cookies with an oven that collects sunlight and traps the shorter wavelengths (heat!).

There is debate about whether chalkboards or whiteboards are better. This experiment explores which leads to better retention of visually-displayed information.

The purpose of this science fair project is to explore whether UV light passes through some colors and not others by looking at blue, red, purple, and clear.

Create a mini plant habitat with your kid to help teach him what it takes to make an ecosystem work.

This activity turns your kid into the family weatherman. Plus, it teaches him to collect data and begin to understand graphing.
