Caribbean Cruise: Examining the Movement and Quality of Organic Matter Over Time From Two Caribbean Watersheds

Particulate organic matter (POM), which consists of small pieces of twigs, leaves, soil, and other items found in the water, is an important component of an ecosystem and the food web. In this study, the scientists wanted to study a certain type of POM called coarse particulate organic matter, or CPOM. The scientists wanted to figure out how the amount and quality of CPOM changed over a period of time in the Luquillo Experimental Forest.

Note To Educators
The Forest Service's Mission
The Forest Service’s mission is to sustain the health, diversity, and productivity of the Nation’s forests and grasslands to meet the needs of present and future generations. For more than 100 years, our motto has been “caring for the land and serving people.” The Forest Service, an agency of the U.S. Department of Agriculture (USDA), recognizes its responsibility to be engaged in efforts to connect youth to nature and to promote the development of science-based conservation education programs and materials nationwide.

What Is the Natural Inquirer?
Natural Inquirer is a science education resource journal to be used by students in grade 6 and up. Natural Inquirer contains articles describing environmental and natural resource research conducted by Forest Service scientists and their cooperators. These scientific journal articles have been reformatted to meet the needs of middle school students. The articles are easy to understand, are aesthetically pleasing to the eye, contain glossaries, and include hands-on activities. The goal of Natural Inquirer is to stimulate critical reading and thinking about scientific inquiry and investigation while teaching about ecology, the natural environment, and natural resources.
