Flash Cards of Common Freshwater Invertebrates of North America contains flash cards depicting 75 different freshwater invertebrate taxa that are both common and widely distributed across North America. Each individual two-sided card features an original high-quality color scientific illustration of an organism on one side and, on the other, the common and scientific name of the organism along with basic questions and answers about the biology, ecology, and environmental tolerances of the pictured organism. In addition to the flash cards, a booklet containing diagrams of body parts, taxonomic classifications, a glossary of 52 terms used in text on the cards, and suggestions for using the cards will accompany each set. These products are based upon illustrations and information contained in J. Reese Voshell's highly esteemed book A Guide to Common Freshwater Invertebrates of North America, although they have been updated to include the most recent and pertinent information on the adaptations and functions of freshwater invertebrates in natural ecosystems and how the organisms respond to environmental stresses created by humans. Flash Cards of Common Freshwater Invertebrates of North America are designed specifically for teaching/learning how to identify common freshwater invertebrates and to understand their biology and ecology - including such important basic information as where the invertebrates live, how and what they eat, how they move or avoid moving, how they breathe, their unique anatomy and behavior, and why they are important to their - and our - ecosystems! Flash cards are acknowledged to be effective teaching/learning resources because they use visualization to associate and integrate diverse information. Flash cards are equally effective for group learning or individual instruction. The flash cards offered here have been designed in accordance with the principles of interpretation - effective communication, emotional or intellectual connections, revelation based on information, and provocation - all of which bring about the desire for learning. These cards will be especially useful for teachers and students at all levels of instruction, naturalists, water quality monitors, interpreters of freshwater environments and ecosystems, landowners, resource managers, anglers, and others with interest in, or responsibility for, studying, interpreting, monitoring, or managing freshwater resources. Flash Cards of Common Freshwater Invertebrates of North America comprises three sets of cards; each set contains 32 cards total. Sixty taxa appear in only one set and fifteen taxa appear in two sets; those taxa that appear twice are treated at different levels of detail in the two sets. The cards are printed in full color on synthetic material with uv-resistant inks and are coated to further protect against fading. Each card measures 4" wide x 6" high. SET ONE covers the major classes and orders of freshwater invertebrates.
