Beating the Heat in the World's Big Cities
Read the Fine Print
Rating
0.0 stars

This article describes the urban heat island phenomenon and provides an overview of a research project investigating the effect as seen in New York City. Topics include the large proportion of earth's population now living in cities and the exacerbating effect of climate change on heat islands. A discussion of the study in New York describes how researchers used LandSat imagery to correlate the hottest areas of the city with a lack of vegetation (especially trees) in those areas. Suggested mitigation solutions included planting more trees, converting roof surfaces to reflect light, and the use of 'green roofs', specially constructed systems that use living plants as the outermost layer.

​​Nature has the power to make children healthier, happier and smarter. But over the last few generations, childhood has moved indoors, leaving kids disconnected from the natural world. This worldwide trend has profound implications for children’s healthy development—and the future of our planet.

Community Ecology: Feel the Love - Crash Course Ecology #4
Rating
0.0 stars

Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous, so a lot of interactions are actually about side-stepping direct competition and instead finding ways to divvy up resources to let species get along. Feel the love?

Connecting Kids to Nature: Invasive Species
Read the Fine Print
Rating
0.0 stars

Moving plant and animal species to new environments can be beneficial, but can often cause environmental and economic harm.
The next time you are outdoors, introduce the term invasive species to children and discuss its meaning by asking:
• How would this area look different if a family of elephants lived here?
• What impact would the elephants have on the plants and animals nearby?
• Where do elephants live in the wild? Why don’t elephants live here?

Conservation and Restoration Ecology: Crash Course Ecology #12
Rating
0.0 stars

Hank wraps up the Crash Course on ecology by taking a look at the growing fields of conservation biology and restoration ecology, which use all the kung fu moves we've learned about in the past eleven weeks and apply them to protecting ecosystems and to cleaning up the messes that we've already made.

Defining Desertification
Read the Fine Print
Rating
0.0 stars

This feature article from the National Aeronautics and Space Administration (NASA) Earth Observatory discusses the use of satellite imagery to evaluate desertification which is occurring in the Sahel, a region of central African savannah that forms the boundary between the Sahara Desert to the north and the wetter, more fertile regions to the south. Topics include the use of Very High Resolution Radiometer (VHRR) data, obtained from National Oceanic and Atmospheric Administration (NOAA) meteorological satellites, to develop a vegetation index, and exactly how the term 'desertification' should be defined in order to distinguish temporarily degraded land from that which has permanently lost productivity.

Earth Observatory: Clouds and Radiation
Read the Fine Print
Rating
0.0 stars

The study of clouds (where they occur, their characteristics, etc) plays a key role in the understanding of climate change. This site discusses how the relative thickness and altitude of various cloud types result in their either reflecting solar radiation or transmitting and trapping it, thereby warming Earth's surface. It features text, a scientific illustration, and links to other relevant topics and datasets.

Rating
0.0 stars

This site provides a brief description of the Dustbowl in the American Great Plains during the 1930s and relates its effects to what is occurring presently in the Sahel of North Africa. In this dry savannah environment, human activity coupled with prolonged drought are causing desertification. The site features text, satellite imagery, and links to other related materials.

Exploring Environmental Issues: Biodiversity
Read the Fine Print
Rating
0.0 stars

Exploring Environmental Issues: Biodiversity was developed by Project Learning Tree in partnership with the World Wildlife Fund. In this sixty-page module, students learn that decisions about growth and development, energy use and water quality, and even human health, all rest to some extent on perspectives about biodiversity. Educators and students step back from biodiversity issues and specific species to examine broader concepts and larger connections—not just biological, but political, cultural, ethical, and economic as well. Educators can download the complete Exploring Environmental Issues: Biodiversity module at no cost.

Exploring Environmental Issues: Biotechnology
Read the Fine Print
Rating
0.0 stars

The word “biotechnology” usually conjures images of modern techniques and topics of controversy such as cloning, stem cell research, and genetically modified organisms. However, the practice of manipulating organisms to create a product has long been used by human societies. Our Biotechnology Series is designed for high school and community college educators in the fields of Biology, Environmental Science, Social Studies, and Agriculture. A special effort has been made to construct activities that support instruction in AP Biology, AP Environmental Science, and AP Human Geography. This module was created as a supplement to the Focus on Risk curriculum. Educators can download the complete Exploring Environmental Issues: Biotechnology module at no cost.
