The updated digital Watershed Tour introduces students to stream and river ecosystems through a classroom–based exploration of the virtual Big River watershed. Students learn about stream ecology, water quality, and how their own actions can affect a watershed. Through hands on activities, student groups evaluate simulated water samples to collect chemical and biological data from four mystery sites. They apply their knowledge of watersheds to analyze the data to determine the water quality and identity of their site. They write an action plan for the Big River river keeper for maintaining or improving the water quality at their site.
Activities can be modified to fi t schedules, curriculum needs or learning opportunities. Data sheets and puzzles for each unit can be printed or filled electronically by students using a computer or tablet. Some activity sheets must be printed. Includes Instructor Manual, Student Manual with “On the Way to the Bay” game, classroom color chart, reagents and test tubes for 50 students. NGSS Aligned.
Water resistant data sheets for recording data after sorting and identifying freshwater aquatic macroinvertebrates to Order and some Families level. Includes instructions and formulas for calculating the Pollution Tolerance Index (PTI) Score and Pollution Tolerance Index Rating. Write on, wipe off and re-use. For field or indoor use. English and Spanish. Set of six.
Spiral bound dichotomous key for identification of aquatic macroinvertebrates to Order and some Families level. Color-coded based on Pollution Tolerance level. Includes glossary, body part illustrations and size reference. Water resistant for field or indoor use. Enhancement to Leaf Pack Stream Ecology Kit. English and Spanish.
Set of six.
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.
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.
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.
