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?

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

Determine if âdouble dippingâ chips really spreads more germs than dipping only once per chip.

Science fair project that examines the behavior of water and gravel in creek beds and the formation of sedimentary rocks.

In this science fair project, students use hot and cold water to simulate what happens when a warm front meets a cold one.

This science fair project determines if the allelopathic chemical produced by the black walnut tree biodegrades immediately or persists over several days.

In this science fair project, you'll make a "ghost" appear in a test tube, and learn about what happens when hot water and cold water interact.

This project investigates several commercially decaffeinated tea types (black, green, oolong, white) for the presence of detectable traces of caffeine.

Science fair project which determines if plants really do need water to grow, or whether they just need to be kept wet.

This science fair project idea explores what it takes to create a biosphere, or a self-sustaining ecosystem.

Science fair project which compares the rates of photosynthesis for various light sources. Which type of light will be best for photosynthesis and why?

Science fair project which determines whether plants are able to get enough nutrients from different types of garbage.

Science fair project in which you will stage an election campaign to determine whether people are more swayed by a positive ad or negative ad.

What is mulch? Kids will provide soil with a wet blanket of mulch and see if that helps keep drought-stricken soil damp.

Fudge is one of very few desserts people make at home that is actually crystalline. What happens when the fudge crystallizes at different temperatures?

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

Science fair project which evaluates different athletic shoes in order to find out whether any of them affect a person's ability to run.

Science fair project that compares the properties of different fabrics to determine whether natural or synthetic fabrics are better at wicking away moisture.

Create a double-slit interference out of cardboard. Produce an interference pattern that demonstrates the wave and particle characteristics of light.

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

The objective of this experiment is to find out if cooked beans grow faster, if at all, than uncooked beans.

Science fair project that determines the correlation between the ability of selected materials to conduct heat and a material's density.

This science experiment explores why leaves change color in the fall and the role of photosynthesis in leaf coloration.
