Seed Germination and Moisture— Guided-Inquiry Kit
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.

Discover Life in the Soil— Student Laboratory Kit
Students will be fascinated to find what is living in the upper layer of soil at school
or at home. Students collect a soil sample and extract organisms in a Berlese–Tullgren apparatus. After a few days, students examine the extracted organisms under magnification. After each group identifies the types of organisms in their sample, students compare the biodiversity and population density among other collected soil samples.

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.

Tree Growth Study—Super Value Kit
Plant Wars—
Student Laboratory Kit
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.

Trees contain some of nature’s most accurate records. Students unlock these historical mysteries and uncover environmental trends of the past by studying actual tree round samples. Differences between hardwood and softwood trees, good years of tree growth versus poor years and ages of trees will be determined. Includes 5 sets of three different types of tree round samples, detailed student and teacher notes and all required materials.
