Chesapeake Bay: An Estuary in Crisis

from The Mariners' Museum

Program image

The Chesapeake Bay is the largest estuary in the United States. Its watershed encompasses 64,000 square miles, is home to 17,000,000 people, and includes all or portions of six states. The Bay is also home to approximately 3,600 plants and animals and serves as an economic and recreation resource for humans. But the Bay is suffering.

During this program, students will examine the resources of the Chesapeake Bay, from the years before early European settlement to today. By exploring the changes in the Bay over time, students will discover the factors that have contributed to its decline. The program concludes with a discussion of the changes students can make in their daily lives to improve the health of the Chesapeake Bay, or any other watershed in which they may live.

Participating classes will receive the supplies necessary to perform their own environmental cleanup, and will have the opportunity to post their images and clean-up statistics to a special website

Standards Alignment

National Standards

Grades K-4
Life Science(CONTENT STANDARD C):
ORGANISMS AND THEIR ENVIRONMENTS
• All animals depend on plants. Some animals eat plants for food. Other animals eat animals that eat the plants.
• An organism's patterns of behavior are related to the nature of that organism's environment, including the kinds and numbers of other organisms present, the availability of food and resources, and the physical characteristics of the environment. When the environment changes, some plants and animals survive and reproduce, and others die or move to new locations.
• All organisms cause changes in the environment where they live. Some of these changes are detrimental to the organism or other organisms, whereas others are beneficial.
• Humans depend on their natural and constructed environments. Humans change environments in ways that can be either beneficial or detrimental for themselves and other organisms.
Grades 5-8
Life Science(CONTENT STANDARD C):
POPULATIONS AND ECOSYSTEMS
• A population consists of all individuals of a species that occur together at a given place and time. All populations living together and the physical factors with which they interact compose an ecosystem.
• Populations of organisms can be categorized by the function they serve in an ecosystem. Plants and some micro-organisms are producers--they make their own food. All animals, including humans, are consumers, which obtain food by eating other organisms. Decomposers, primarily bacteria and fungi, are consumers that use waste materials and dead organisms for food. Food webs identify the relationships among producers, consumers, and decomposers in an ecosystem.
• For ecosystems, the major source of energy is sunlight. Energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis. That energy then passes from organism to organism in food webs.
• The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.
DIVERSITY AND ADAPTATIONS OF ORGANISMS
• Extinction of a species occurs when the environment changes and the adaptive characteristics of a species are insufficient to allow its survival.
Earth and Space Science(CONTENT STANDARD D):
STRUCTURE OF THE EARTH SYSTEM
• Water is a solvent. As it passes through the water cycle it dissolves minerals and gases and carries them to the oceans.

Science in Personal and Social Perspectives(CONTENT STANDARD F):
POPULATIONS, RESOURCES, AND ENVIRONMENTS
• When an area becomes overpopulated, the environment will become degraded due to the increased use of resources.
• Causes of environmental degradation and resource depletion vary from region to region and from country to country.
NATURAL HAZARDS
• Human activities also can induce hazards through resource acquisition, urban growth, land-use decisions, and waste disposal. Such activities can accelerate many natural changes.
RISKS AND BENEFITS
• Risk analysis considers the type of hazard and estimates the number of people that might be exposed and the number likely to suffer consequences. The results are used to determine the options for reducing or eliminating risks.
• Students should understand the risks associated with natural hazards (fires, floods, tornadoes, hurricanes, earthquakes, and volcanic eruptions), with chemical hazards (pollutants in air, water, soil, and food), with biological hazards (pollen, viruses, bacterial, and parasites), social hazards (occupational safety and transportation), and with personal hazards (smoking, dieting, and drinking).
• Individuals can use a systematic approach to thinking critically about risks and benefits. Examples include applying probability estimates to risks and comparing them to estimated personal and social benefits.
• Important personal and social decisions are made based on perceptions of benefits and risks.
SCIENCE AND TECHNOLOGY IN SOCIETY
• The effect of science on society is neither entirely beneficial nor entirely detrimental.
• Technological changes are often accompanied by social, political, and economic changes that can be beneficial or detrimental to individuals and to society.

Grades 9-12
Life Science (CONTENT STANDARD C):
THE INTERDEPENDENCE OF ORGANISMS
• Organisms both cooperate and compete in ecosystems. The interrelationships and interdependencies of these organisms may generate ecosystems that are stable for hundreds or thousands of years.
• Living organisms have the capacity to produce populations of infinite size, but environments and resources are finite. This fundamental tension has profound effects on the interactions between organisms.
• Human beings live within the world's ecosystems. Increasingly, humans modify ecosystems as a result of population growth, technology, and consumption. Human destruction of habitats through direct harvesting, pollution, atmospheric changes, and other factors is threatening current global stability, and if not addressed, ecosystems will be irreversibly affected.
Science in Personal and Social Perspectives (CONTENT STANDARD F):
POPULATION GROWTH
• Populations grow or decline through the combined effects of births and deaths, and through emigration and immigration. Populations can increase through linear or exponential growth, with effects on resource use and environmental pollution.
NATURAL RESOURCES
• Human populations use resources in the environment in order to maintain and improve their existence. Natural resources have been and will continue to be used to maintain human populations.
• The earth does not have infinite resources; increasing human consumption places severe stress on the natural processes that renew some resources, and it depletes those resources that cannot be renewed.
• Humans use many natural systems as resources. Natural systems have the capacity to reuse waste, but that capacity is limited. Natural systems can change to an extent that exceeds the limits of organisms to adapt naturally or humans to adapt technologically.
ENVIRONMENTAL QUALITY
• Natural ecosystems provide an array of basic processes that affect humans. Those processes include maintenance of the quality of the atmosphere, generation of soils, control of the hydrologic cycle, disposal of wastes, and recycling of nutrients. Humans are changing many of these basic processes, and the changes may be detrimental to humans.
• Materials from human societies affect both physical and chemical cycles of the earth.
• Many factors influence environmental quality. Factors that students might investigate include population growth, resource use, population distribution, overconsumption, the capacity of technology to solve problems, poverty, the role of economic, political, and religious views, and different ways humans view the earth.
NATURAL AND HUMAN-INDUCED HAZARDS
• Normal adjustments of earth may be hazardous for humans. Humans live at the interface between the atmosphere driven by solar energy and the upper mantle where convection creates changes in the earth's solid crust. As societies have grown, become stable, and come to value aspects of the environment, vulnerability to natural processes of change has increased.
• Human activities can enhance potential for hazards. Acquisition of resources, urban growth, and waste disposal can accelerate rates of natural change.
SCIENCE AND TECHNOLOGY IN LOCAL, NATIONAL, AND GLOBAL CHALLENGES
• Humans have a major effect on other species. For example, the influence of humans on other organisms occurs through land use--which decreases space available to other species--and pollution--which changes the chemical composition of air, soil, and water.

State Standards

Delaware-
Science Standard 5
Earth’s dynamic systems are made up of the solid earth (geosphere), the oceans, lakes, rivers, glaciers and ice sheets (hydrosphere), the atmosphere, and organisms (biosphere). Interactions among these spheres have resulted in ongoing changes to the system. Some of these changes can be measured on a human time scale, but others occur so slowly, that they must be inferred from geological evidence.
• Surface water always flows downhill. Areas of higher elevation separate watersheds. In Delaware, this water eventually reaches the Delaware River, the Delaware Bay, the Atlantic Ocean or the Chesapeake Bay.

District of Columbia-
Grade 4-
