Macro Mania is a classroom adventure that introduces the use of stream macroinvertebrates to determine water quality. Lecture material sets the scene for the activity.
Students will learn about the influence of land use on water quality and the practice of macroinvertebrate sampling to measure water quality. Six teams will be given a deck of macroinvertebrate cards representing a sample of macroinvertebrates from one of three sites, a poster-sized sorting sheet and a map. By sorting the deck of cards onto the sorting sheets, students will determine the water quality at their site from the distribution of macroinvertebrates in their sample. Optional math, public speaking, writing, art and card game extensions will further emphasize the land use/water quality connection. Includes a deck of cards and sorting sheets for six teams. Also includes Macro Mania manual containing background information, step-by-step instructions for activities and extensions. Colorful Macro Mania classroom poster is also included!
This kit tests for Iron using the Octa-Slide 2 Comparator. Range/Sensitivity is 0.5, 1.0, 2.0, 3.0, 4.0, 6.0, 8.0, 10.0 ppm Fe.
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.
Designed for the testing and study of saline systems – oceans, bays, salt marshes, etc. This field-friendly outfit contains individual test modules for seven key salt water test factors, water sampling bottles, three supplemental handbooks now available as a download, and data sheets. The downloadable handbooks include A Laboratory Manual for Marine Science, Limnology, and Investigating Water Problems.
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 kit tests for nitrate and phosphate in water using the LRC Comparator. Range/sensitivity is 0.2, 0.4, 0.6, 1.0 ppm NO3–N; 0.2, 0.4, 0.6, 1.0 ppm PO43–.
These 6″ x 4″ (15 x 10cm) plastic zipper top bags have instructions for collection and preparation of soil samples printed directly on each bag. By preventing contamination or accidental mixing of different samples, these convenient soil bags help insure accurate test results.
Package of 100.
Determine turbidity or degree of visibility in natural waters with this weighted 20 cm diameter disk.
Too Shallow for a Secchi Disk? Turbidity is easily measured by using a standardized turbidity reagent to match the turbidity of a water sample. All the necessary apparatus and reagents needed to test four basic water quality test factors and detailed instructions are housed in a secure foam insert within a rugged field carrying case. Economical reagent refill packages are available for either the entire outfit or individual reagents.
