Use this set of 18 full color flash cards alone or as an addition to any macroinvertebrate activity. (Included in the Leaf Pack Experiments Stream Ecology Kit). The front of each card features a full-color photograph of a common macroinvertebrate in its natural environment. A list of dichotomous characteristics, a measuring scale, and detailed drawings on the back of each card aid in the identification process.
Helpful notes prevent confusion between macroinvertebrates with a similar appearance. A hole can be punched in the wide border of the laminated cards so they can be organized on a ring for field or classroom use.
This kit tests for nitrate or nitrite using the Octa-Slide 2 Comparator. Range/sensitivity is 0.25, 0.5, 1.0, 2.0, 4.0, 6.0, 8.0, 10.0 ppm NO3-N.
TesTabs® kit for measuring pH. Ideal for younger students and teachers who would like an alternative to liquid pH indicators. Ideal companion to Soil NPK Kit (Code 3-5880).
Stainless steel sampler is designed for use on soft bottoms (sand or silt). A simple trigger holds the sampler open while lowering to cover a uniform area. Scissor design closes sampler, retrieving a volume of sediment to the surface for analysis.
A popular, economical tool for learning the basics of water quality. No other test kit on the market compares to this portable, easy-to-use water testing kit. Students will have fun analyzing sample water for eight different test factors. This complete kit includes a manual with step-by-step, diagrammed instructions; an easy-to-use laminated color chart, and all the necessary apparatus and non-hazardous TesTabs® to test ten water samples (three samples for coliform).
Use this kit at home or pack it into a field bag and explore the water quality of natural aquatic systems nearby. The Earth Force Low Cost Water Monitoring Kit can be used to test fresh, brackish, or saline aquatic environments.
A great learning and water testing tool for any investigator ages 8 to 98! Ideal for citizen monitoring efforts, too.
(now offered with bi-lingual instruction manuals in English and Spanish)
A creepy, crawly, wet investigation of the health of streams, ponds, and other freshwater environments. Following the easy-to-read BUGKIT manual, one to two students learn to collect, observe, sort, and identify aquatic insects as a tool for measuring water quality.
Students can complete the activity at home after collection or spend an afternoon outdoors beside a stream. The BUGKIT includes mesh leaf bags for collection, trays and plastic dishes for sorting, a magnifying lens, BUG GUIDE, and a BUG BOARD identification chart. Ideal for bug-hunters, age 8 and up.
The Insta-TEST® Copper & Iron Test Strip Kit measures Copper levels from 0-3.0 ppm and Iron levels from 0-5.0 ppm. The Copper test strip has been improved with a one-dip formula that offers very distinct colors. The one-dip Insta-TEST® Iron test strip formula eliminates the need to pre-treat the sample with a reduction tablet prior to measuring Iron with a test strip. The Iron strip makes the testing process simpler with just one dip of the strip into a pool or spa before matching the reaction to a color chart on the bottle. There are 25 strips packaged per bottle.
This kit tests for Nitrate-Nitrogen using tablet reagents and the Octa-Slide 2 Comparator. Range/sensitivity is 0, 1, 2, 4, 6, 8, 10, 15 ppm NO3-N.
A rugged field carrying case houses individual test kit modules and valuable handbooks to assist and supplement soil science studies. Each individual test module includes complete instructions, A Study of Soil Science handbook now available as a download, and all the necessary apparatus and reagents to perform 50 soil macronutrients tests.
A comprehensive introduction to the study of soil properties and nutrients. Includes the popular and easy-to-use soil sampling tube, soil sample bags, the Soil Texture Unit, and individual test modules for four important soil test factors (see Specifications).
