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.

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

This science project is to discover which Black Walnut tree tissue contains the most concentrated amount of Juglone, a substance that works like an herbicide.

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

This science fair project compares the allelopathic chemical produced by the Black Walnut tree to a commercial herbicide in stopping the growth of a shrub.

Learn with makes water molecules work with this fun and easy science activity!

In this experiment two environments will be compared: a room with interior design that uses correct Feng Shui versus one with incorrect Feng Shui.

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

This experiment explores whether music affects the growth of bacteria and could help figure out better ways to process sewage and other microbe-assisted duties.

This science fair project will go beyond the simple definition of conservation to explore the different facets of what conservation means.
