An inquiry-based approach to watershed education. Students ask questions, learn to design and implement a river study from acquiring and reading watershed maps to determining/scheduling study sites and water quality testing. They will then compile and analyze results, share the results with their community, and learn to take action through a variety of productive avenues and disciplines.
A great tool for beginning a school-based, community involved water monitoring program. Includes a valuable, comprehensive manual and a set of 9 test factor modules. Same economical, safe, TesTabs® method as the Earth Force Low Cost Water Monitoring Kit. Each module contains easy-to-read, diagrammed instructions; a color chart; a test factor flashcard; and all the necessary apparatus and non-hazardous TesTabs® to perform 100 tests (44 tests for coliform bacteria; unlimited for benthic macroinvertebrates and turbidity).
Recommended for grades 4 and higher. Also ideal for community groups/citizen monitoring efforts.

Colonize submerged leaves in stream habitats. The ability of freshwater macroinvertebrates to flourish depends upon the properties of the water and conditions in the environment. The relative abundance and variety of freshwater macroinvertebrates can be used as bioindicators to assess the quality of the water and the effects of land use on the environment.
This Alkalinity test kit provides total alkalinity readings only, using a Direct Reading Titrator. Testing range/sensitivity 0-200 ppm/4 ppm as CaCO3.
This kit tests for Total, Calcium and magnesium hardness by using the Dropper Bottle method. All results are as CaCO3. Range/sensitivity is 1 drop = 10 ppm or 1 gpg CaCO3.
This kit tests for Nitrite-Nitrogen using the diazotization/coupling reaction to form a pink color. The results are determined using the Octa-Slide 2 Comparator. Range/sensitivity is 0.05, 0.10, 0.20, 0.30, 0.40, 0.50, 0.60, 0.80 ppm NO2-N.
A 12″ galvanized steel sampler with a 1″ core diameter, saw-toothed tip, and cut-away side for examination of core prior to removal for testing.
A complete outfit for pond fish culture, ideal for fresh water analysis. Nine critical test factors can be efficiently and accurately determined on-site. Designed with field analysis as a priority; all reagents, components and accessories are arranged in pre-drilled ethafoam. Short form instructions are provided in a handy lid label for easy access. Long form instruction booklet provides detailed instructions and test kit diagram. Unit is supplied complete with labware, accessories, sampling bottle, and reagents for 50 tests of each factor.
This Sulfide Test kit tests for sulfide using the Octa-Slide 2 Comparator. Range and sensitivity is 0.2, 0.5, 1.0, 2.0, 5.0, 10.0, 15.0, 20.0 ppm S2-.
An 8″ resin column (10.25″ total height) that softens up to 70 gallons of medium hard water (7 gpg hardness) before requiring regeneration or fresh resin. Model S softener is furnished in the Model AT-38 and AT-Q-38 outfits.
Help kids understand the life cycle and habitats of freshwater aquatic macroinvertebrates with this set of flashcards and manual. The 22 full-color cards feature photos of both immature and adult insect stages, and detail life cycle and habitat information. The accompanying manual contains facts on insect characteristics, life cycles, taxonomy, classification, food webs and how macroinvertebrates can be indicators of water quality.
Instructions for activities with the cards are included. The Freshwater Aquatic Macroinvertebrate: Insect Life Cycle and Habitat Flashcards can be used as an extension to the Freshwater Aquatic Macroinvertebrate: Identification Flashcards and the Leaf Pack Experiments Stream Ecology Kit.
