ABOUT THE ANNOTATIONS IN "EARTH SCIENCE—CORE MATERIALS"
Curriculum materials are arranged alphabetically by title in each category (Core Materials, Supplementary Materials, and Science Activity Books) in chapters 1 through 4 of this guide. In addition, each annotation has a two-part entry number. For each entry number, the chapter number is given before the period; the number after the period locates the entry within that chapter.
For example, the first entry number in chapter 1 is 1.1; the second entry in chapter 2 is 2.2, and so on.
The entry numbers within each curriculum chapter run consecutively through Core Materials, Supplementary Materials, and Science Activity Books.

2.3 Ecosystems. STC. Field-test ed. Washington, D.C.: National Science Resources Center, 1992.
Grade: 5 In Ecosystems, students learn about the interdependence of organisms and the natural environment by using 2-liter soda bottles to set up, observe, and experiment with two miniature ecosystems—an aquarium and a terrarium. After studying the two separate ecosystems, students connect them and observe the ecocolumn, noting any changes that may indicate an imbalance in the system. They read about aquatic and terrestrial organisms—plants, algae, fungi, bacteria, and animals—and pollution. They study habitat changes and conduct experiments simulating the effects of acid rain, road salt, and fertilizer. As a final activity, students in small groups investigate a real ecosystem in danger—the Chesapeake Bay. They read about the problems of the bay, analyze the situation from several points of view, propose possible solutions, and begin to grapple with the trade-offs involved in various solutions.
Ecosystems is a 16-lesson unit that requires 8 weeks to complete. The teacher's guide includes a unit overview, the 16 lesson plans, an
