The Science Fair Project in a Bag
name given by
which some plants chemically inhibit the
germination, or growth of competitors. The chemicals may be released
cell tissues directly into the air (volatile chemicals), or released
soil from the roots or from decomposing leaves. The all time champion
allelopathy is The Black Walnut Tree, which
produces a potent pesticide and herbicide called “juglone”
(5 hydroxy-1, 4-napthoquinone), which occurs naturally in
all parts of the tree and thereby creates
a protective zone around the Black Walnut Tree.
Designed as a hands-on activity this kit includes everything needed for student investigators to compare the allelopathic affects of juglone, the chemical agent produced by the Black Walnut tree, on fast growing plants over the course of 7 days and its biodegradability in soil.
Because preparing juglone from Black Walnut tree tissue can
be quite messy we recommend this kit for hands-on use by boys and girls
upper elementary and middle school grades. This activity is also a great teacher demonstration for younger students.
The Allelopathy Investigation Kit includes:
Radish, corn and tomato seeds
1.5 oz. Black Walnut juglone solution
Planting cups & plastic spoon
Interactive CD-ROM with lab investigations, data input and presentation software
Black Walnut tree tissue
Your next science fair project or class presentation will be a
rewarding experience. Our clear and scientifically designed
experimental investigations will help you make the grade as you
discover how allelopathy chemically inhibits the growth other plants
and how this chemical warfare between plants may have potentially
important applications for agriculture and home lawn care.
Each kit contains the major items needed to conduct two scientific
investigations and our ready-to-use data reporting CD will enable you
to record your results quickly and efficiently, you simply enter the
data and print out your results.
Parents and Teachers:
This science kit was not only design for classroom use, but also as a
science fair activity. The major supplies needed to setup, conduct, and
record the results of allelopathy investigations to post on a Tri-fold
display board are included in the kit.
A real-world application for the data gained from this science fair
project is to consider the use of Juglone and/or other natural
allelopathic substances as potential alternatives to the use of
traditional commercially produced herbicides with all of the
accompanying ill effects to people and the environment that commercial
The materials in the kits provide highly interactive learning; they
conform to the National Science Standards, the various State Education
Standards, and are thematic and interdisciplinary.
