Characteristics of Algae— Student Laboratory KitDiscover photosynthetic algae and increase microscopy skills as students compare living and preserved species of Chrysophyta, Euglenophyta and Chlorophyta. After inspecting internal and external features of specimens on prepared microscope slides, students observe live samples of the organisms to study their behavior. A great introduction to a pond or marine water classification lab!FB1930 I $68.95Gibberellic Acid and Plants—Student Laboratory KitWhat effects do hormones have on plants? Will varying concentrations affect plants differ-ently? In this introduction to plant hormones, students see firsthand the powerful effects of gibberellic acid by placing varying solu-tion concentrations on bean seedlings then observing and recording the exciting results. Students also can design and conduct their own gibberellic acid experiments. FB0478 I $107.75Plant Wars— Student Laboratory KitAllelopathy 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.FB1563 I $33.45MIDDLE SCHOOL LIFE SCIENCEPLANTS, CONTINUEDSeed Germination SetThis convenient selection of seeds for germination studies and experiments includes two types of dicot seeds (radish and pea) and two types of monocot seeds (barley and corn) so students can witness firsthand the developmental differences from seed to young plant. FB0584 I $14.65Growing Gloves—Super Value Laboratory KitLet students observe all the structures of “unknown” germinating seeds right on your classroom window. Clear, plastic five-fingered gloves allow comparison of plant embryos as they grow and develop into plants. Students will easily notice the defining structures of monocots and dicots and be able to catego-rize them accordingly. FB1807 I $37.75Hydroponics ExperimentThe unique growth chambers in this kit enable students to view plants thriving in a nutrient solution and not in soil. They will compare the growth phases of five different plants and also experiment with induced nitrogen and iron deficiencies. Two complete hydroponic growth chambers are included.FB0477 I $103.45
