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.
This kit tests for Nitrate-Nitrogen using the LRC Comparator. Range/sensitivity is 0, 0.2, 0.4, 0.6, 0.8, 1.0 ppm NO3-N.
Safe, easy, and economical! Students can perform up to fifty tests each for nitrogen, phosphorus, and potassium levels using non-hazardous TesTabs®. Each kit includes the necessary apparatus, simple diagrammed instructions, and a laminated color chart.
The NPK Soil Test Kit was specifically designed to meet the needs of the GLOBE Program™ (Global Learning and Observations to Benefit the Environment). This soil test kit is fun to use and easy to ship anywhere! Ideal for upper elementary, middle, and high school students.
Collect water samples quickly and easily! This newly designed horizontal water sampler allows water to be sampled at specific depths. A 20 meter calibrated line, marked at one meter intervals, is included. The clear acrylic tube allows a visual inspection of the sample prior to dispensing and holds approximately 1,200 mL of sample.
Send the weighted messenger down the line to trip the closing mechanism at the desired depth.
The LaMotte Acid Rain Study Outfit includes dependable tools necessary to make surveys of acid precipitation, and determine the pH levels of local ponds, lakes, and streams. This complete outfit includes a durable, tapered rain gauge; an easy-to-use pH test kit; study guide; and activity sheets. The comprehensive study guide and support materials will stimulate classroom activities and discussions. Recommended for grade levels 5 and above.
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.
