Discover Life in the Soil— Student Laboratory KitStudents 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 appa-ratus. 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.FB1991 I $31.75Nutrient Deficiency in Plants—Hydroponics Laboratory KitStudents 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.FB1231 I $70.05Hydroponics SystemCompact freestanding hydro-ponics gardening system fits in just 2½ square feet. Grow flowers, herbs and vegetables in six individual planters rest-ing in a pump-aerated nutrient solution that allows plants to absorb food and water as needed and grow without soil. System includes reser-voir, formed cover, growing medium, planters, seed starter cubes, pump and tubing, hydroform nutrient, pH test kit, illustrated instructions and water level indicator.FB1680 I $121.50Stomata and Transpiration Rates—Student Laboratory KitStrengthen students’ knowledge and under-standing of stomata and transpiration with an engaging two-part lab activity. Students observe the physical properties of stomata and determine the average number by microscopically viewing leaf impressions. They then investigate and measure plant transpiration rate under various conditions to learn about photosynthesis, guard cells and gas exchange. FB1861 I $73.50FLINN SCIENTIFIC I MIDDLE SCHOOL LIFE SCIENCEPLANTS, CONTINUEDSeed Germination and Moisture—Guided-Inquiry KitStudents use a variety of “liquids” on radish seeds to determine their impact on germi-nation. The results will surprise students on how sensitive seeds can be to their surround-ings. Teacher Notes, reproducible student handouts and all necessary chemicals and specialized equipment are provided.FB1634 I $37.70
