Allelopathy is when plants release chemi- cals that inhibit the growth of other plants. A well-known example is the black walnut, which secretes juglone, a toxic substance to many plants like tomatoes, which suffer “walnut wilt” and die if their roots contact the tree’s roots. Students germinate two types of seeds to determine allelopathy between the species.

What effects do hormones have on plants? Will varying concentrations affect plants differently? In this introduction to plant hormones, students see firsthand the powerful effects of gibberellic acid by plac- ing varying solution concentrations on bean seedlings then observing and recording the exciting results. Students also can design and conduct their own gibberellic acid experiments.

Students use a variety of “liquids” on radish seeds to determine their impact
on germination. The results will surprise students on how sensitive seeds can be to their surroundings. Teacher Notes, repro- ducible student handouts and all necessary chemicals and specialized equipment are provided.
FB1634 I $37.70
Nutrient Deficiency in Plants—
Hydroponics Laboratory Kit
Students compare hydroponically grown plants with plants grown in soil. In their experimentation, they will also study the effects of missing macro- and micro-nutri- ents. Pre-mixed nutrient solutions, seeds and growth chamber materials make preparation time minimal. Includes detailed instructions, hydroponics background and anticipated results.

IMSA Fusion—Out of the Silo: Agronomic STEM
Use the IMSA Fusion Out of the Silo: Agronomic STEM curriculum Premium Module Kit to explore STEM topics in the context of agronomy, the science and technology of producing and using plants for food and fuel. Students investigate plant genetics, soil science, crop management systems, new technologies and other issues at the forefront of agronomic research. Data analysis, policy development, efficient process design and problem solving will engage learners in a deeper understanding of the role of agriculture in Illinois and beyond.
