[Environmental Education Units.] Succession in a Micro-Aquarium. Minnows and Models. Brine Shrimp.
Minneapolis Independent School District 275, Minn.
These three booklets are outlines of teaching procedures, using living material, designed for elementary school children. While emphasizing science, many opportunities are provided for exercises in mathematics, art, and writing, thus integrating the curriculum. All booklets contain exercises on data collection and organization; two have exercises designed to give practice in estimating population sizes from samples. Brine shrimp are used to provide experiences with life cycles and interactions with environmental factors. Minnows provide data needed to build a mathematical model: the relationship between temperature and activity. Emphasis is placed on testing predictions (interpolated and extrapolated) to check the validity of the model. Collection of pond water, and observations of changes in numbers and variety of organisms in a micro-aquarium is intended to make children aware of the general applicability of the concept of change in natural communities. This last activity also introduces the necessity for sampling under standardized conditions. Some theoretical background material is included. This work was prepared under an ESEA Title III contract.
