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

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

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

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

This science fair project compares the allelopathic affects of juglone, a chemical agent produced by the Black Walnut tree, on two plants.

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.

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.

This science fair project uses paper chromatography to investigate whether black, brown, orange, and purple are pure colors or mixtures of other colors.
