Description

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object, co-developed between NOAA and NSTA, is the fourth of four Science Objects in the Coral Reef Ecosystems SciPack. It explores the natural and human causes of ecosystem stress. Human beings live near coral ecosystems and use them in a variety of ways. Increasing amounts of stress is brought on these ecosystems as humans continue to modify the surrounding environment as a result of population growth, technology, and consumption. Human destruction of habitats through direct harvesting, pollution, atmospheric changes, and other factors is threatening the stability and overall health of many coral reefs. Human activities may also exacerbate the impact of natural disturbances on coral reefs or compromise the ability of the reef to recover from events such as hurricanes, tsunamis, or disease.

  • Life Science
    • Organisms and environments
      • When the environment changes, some plants and animals survive and reproduce, and others die or move to new locations.
      • 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.
    • Populations and ecosystems
      • A population consists of all individuals of a species that occur together at a given place and time. (5-8)
      • All populations living together and the physical factors with which they interact compose an ecosystem. (5-8)
      • Populations of organisms can be categorized by the function they serve in an ecosystem. (5-8)
      • Food webs identify the relationships among producers, consumers, and decomposers in an ecosystem. (5-8)
      • Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates. (5-8)
      • Lack of resources and other factors, such as predation and climate, limit the growth of populations in specific niches in the ecosystem. (5-8)

Review on Coral Reef Ecosystem: Crisis
  Ronaldo Relador (Bowie, MD) on February 29, 2012
  Presenting the truth on a very special ecosystem in a very balance way. This is a material for advocates of defense for the environment.

Stresses to a Coral Reef
  Adah (San Antonio, TX) on October 20, 2010
  This Science Objects describes and elaborates about the stresses, both biotic and abiotic, to a coral reef ecosystem. Subtopics include hurricanes, both positive and negative effects of tsunamis, reef eating predators, bleaching and coral diseases. This is followed by human interactions such as commercial exploitation, runoff from land, invasive species, ship groundings, marine debris, tourism and recreation. Two student preconceptions address those held by elementary students. There is an animation about Degree Heat Week in 2005. This Science Object provides a link for Email Help from a Content Mentor. The Science Object is peppered with check for understanding questions throughout it and ends with a short quiz. This is an excellent overview of the problems facing coral reefs but it also provides a section about stewardship of the reefs. This resource overflows with a wealth of information and provides a strong background understanding of the ecological problems facing this un

Thourough description of stresses to ecosystem
  David K on January 15, 2011
  This science object looks at both natural and human causes to the damage and stress on coral reef ecosystems. This information is presented in list form (4 topics for natural causes and 8 topics for human causes) and concludes with information on endangered species and ideas for stewardship. This object has a wealth of information with a good bit of review questions and can supplement any discussions or units on humans interacting with their environment. Very few interactive components, though.
