Logjams and Beaver Dams – Vol. 1 No. 18
Carbon is naturally stored in the environment. In fact, carbon is in every living thing. Some habitats are better at storing carbon and that impacts the entire carbon cycle. In this article, scientists explore how carbon is stored in mountainous areas.

Standards addressed in this Monograph:
Next Generation Science Standards
- ESS2.C-M1Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
- ESS2.C-M5Water’s movements—both on the land and underground—cause weathering and erosion, which change the land’s surface features and create underground formations.
- LS2.A-M4Similarly, predatory interactions may reduce the number of organisms or eliminate whole populations of organisms. Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in these competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared.
- LS2.B-M1Food webs are models that demonstrate how matter and energy are transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.
- LS2.C-M1Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
- LS4.D-M1Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling.
- MS-ETS1-2Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
- MS-ETS1-3Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
- MS-ETS1-4Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
- MS-LS2-3Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
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.
-
Meet the Scientists
Introduces students to the scientists who did the research. This section may be used in a discussion about careers in science.
-
What Kinds of Scientist Did This Research?
Introduces students to the scientific disciplines of the scientists who conducted the research.
-
Thinking About Science
Introduces something new about the scientific process, such as a scientific habit of mind or procedures used in scientific studies.
-
Thinking About the Environment
Introduces the environmental topic being addressed in the research.
-
Introduction
Introduces the problem or question that the research addresses.
-
Method
Describes the method the scientists used to collect and analyze their data.
-
Findings & Discussion
Describes the results of the analysis. Addresses the findings and places them into the context of the original problem or question.
-
Reflection Section
