Aquatic Insect Identification Flashcards

Aquatic Insect Identification Flashcards

Use this set of 18 full color flash cards alone or as an addition to any macroinvertebrate activity. (The set is 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.

Watershed Tour™

Watershed Tour Kit

Introduce students to stream and river ecosystems through a classroom-based tour of a virtual watershed.

Geared toward students in grades 4-8 and designed for teachers who are unable visit a stream with their students.

Students will learn about stream ecology, water quality issues, and their own connection to a watershed.

Through a week long series of hands-on TesTab® tablet tests, games, and activities, students will “test” four stations along a river continuum — from the headwaters to the mouth of the river as it enters the estuary — to study how the river changes and how human activities can influence water quality. Includes lecture materials, illustrated handouts, teacher’s tips, test procedures, TesTab reagents, data sheets, and games. TesTab reagents and test tubes for 30 students in groups.
