A variety of symbiotic relationships exist between sharks and other marine species in this segment from Nature.

In this video segment adapted from the International Institute for Sustainable Development, Inuit observers describe how their traditional understanding of weather patterns is being challenged by unpredictable weather behaviors.

In this video segment from Louisville Life, high school students in Louisville, Kentucky describe the benefits of creating rain gardens as a solution to non-point source water pollution.

In this ecology investigation, students will build and place rock baskets to collect benthic macroinvertebrates in a local waterway. They will observe and identify their macroinvertebrates and use the data to determine the pollution tolerance index for various areas of a river.

This article highlights activities for elementary students that model icebergs and develop an informal understanding of the concepts of buoyancy and density. Suggestions for inquiry-based activities are included.

Learning Assistants are used to facilitate student discussion in peer instruction during clicker questions (i.e., classroom response systems), by asking Socratic questions, emphasizing reasoning, and probing student thinking.

Using quadrats along line transects in two different habitats, students will gather data which will provide evidence that shows the interrelationships between vegetation types and small mammal populations

This activity is a field investigation in which students conduct a plant survey of two study plots, analyze their findings through graphing and mathematic models, investigate the impact of human activity in the general area (optional) and generate questions for further investigation of the study plots.

This activity is a field investigation where students will compare the biodiversity of two separate habitats based on the collection and identification of insects.

This article provides ideas and lessons on how elementary teachers can integrate webcams from the Arctic and Antarctica into their teaching. Five webcams are highlighted as well as three lessons on writing poetry and observing animal behavior.

In this lesson designed to enhance literacy skills, students examine our growing waste problem and learn about strategies we can use to lessen the strain on our landfills and Earth's natural resources: reduce, reuse, recycle.

This video segment adapted from Texas Parks and Wildlife Department explores the role of the wetlands in our environment, including providing habitats for wildlife, acting as natural water filters, and playing a part in the greater water cycle.

The use of new technological motion sensing cameras creates a motivation for students in this life science lesson.

In this ZOOM video segment, cast member Francesco follows the paper trail to find out what happens to his recyclables. He visits a material recovery center and learns how paper is recycled and the number of trees that are saved as a result.

In this adapted video segment, ZOOM guest Laura shows us some of the natural features of Yellowstone National Park, including geysers, hot springs, fumaroles, and mud pots, as well as some of the wildlife.

In this video segment adapted from the College of Menominee Nation, learn about the emergence of invasive forest species and diseases and their possible impact on the Menominee tribal forest.

This video segment adapted from Last Oasis explores the use of new dams as a way to provide or store water. In the 1990s, the city of Denver was looking for a new source of water for its growing population, and its plan to build a new dam suddenly became highly controversial.

This is a field investigation in which students test water quality in 2-3 areas using their own testable question.

This activity is a 3 part lab activity where students create a model of an area in a community. The students test how dirty water flows through their models observing where water is filtered or not. Using what was learned by the models, students will draw a community scene that has man made areas alongside areas that benefit groundwater filtration.

In this video segment adapted from ZOOM, visit a water treatment plant and learn how water from a local reservoir is turned into drinking water.
