The Phoenix metropolitan area, like many large cities, has problems with air pollution at certain times of the year. You can do a simple experiment to determine some of the factors that affect air pollution.

This video from First Alaskans Institute spotlights the Alaska Native community of St. Paul and its hands-on commitment to care for the land and animals on which it depends.

This presentation offers an overview of the developing concept of The Anthropocene -- a term coined to describe our current geological epoch, in which human impact on the planet will leave a permanent trace.

This video segment from the Nevada Department of Wildlife looks at various species of bats and how they impact the environment.

This Nature video segment explores how the relationship between humans and grizzly bears has changed over the course of American History, and it describes the closing of the Yellowstone National Park garbage dumps in the 1970s.

Learn about the precautions humans must take in the face of a growing grizzly bear population in this video from Nature.

This video lesson aims to motivate students about chemistry and to raise their awareness about how chemistry helps in solving certain environmental problems. In this lesson, the air pollution problem created by cars and other vehicles is presented. The lesson will highlight causes of this problem, harmful products from it and possible solutions. There will also be discussion of ways to convert the pollutants produced by burning oil in vehicles into more friendly products.

Suney Park wants her students to know that what they learn in class is relevant to their lives and the world. In this introduction, she shows us how her students come up with a plan to recreate the Earth and its atmosphere and test their own hypotheses about rising CO2 levels.

Suney Park's hands-on activity has her students making the greenhouse effect happen in a model. Using a light bulb for the sun, they create different control groups that imitate Earth's atmosphere with the help of a soda bottle. This adds up to a meaningful experience that connects what students learn in class to real-world events.

After a month studying climate change, students create models of the earth and its atmosphere, and design experiments to test the variables involved in climate change. Students write their own driving questions, develop hypotheses, and build the models to use in their experiments.

Suney Park has her class of scientists set up their experiments step-by-step. Even though it can be chaotic and mistakes can be made, there is purpose and meaning to having the kids be responsible for all aspects of the experiment and the learning that goes on in that process.

This video segment from Nature shows the destructiveness of the shark fin and shark cartilage industries.

In this video segment adapted from LOKE Films and the Arctic Monitoring and Assessment Programme, learn how human populations in the Arctic are affected by industrial contaminants in the food chain.

In this video profile produced for Teachers' Domain, meet teacher Dustin Madden, an IŰ__ŒóíŠupiaq who hopes to inspire students to take an active role in protecting the natural environment by giving them a foundation in math and science.

In this jigsaw, students will graph various Bald Eagle population numbers and determine the impact humans have had on the eagle. Specifically, they will investigate why the Bald Eagle was listed as endangered, the affects of DDT on eagles, and the affects of lead. Based on an original activity titled "Bald Eagle Population Graphing" from The Raptor Center, University of Minnesota http://www.cvm.umn.edu/raptor/prod/groups/cvm/@pub/@cvm/documents/asset/cvm_66866.pdf

In this lesson, students will learn what erosion is and how human actions influence erosion. Includes introduction, demonstration instructions, and questions for wrap-up discussion.

NGSS: K-ESS3-3

Time: 50 minutes

Materials: plastic containers with sand and gravel, sponges, and plastic cups.

The rapid depletion of fossil fuels and the rising sea level from the warming of the earthŐs atmosphere are converging to dramatically alter our future. Edward Mazria, founder of Architecture 2030, unveils a new study of sea level rise showing fly-over 3D images depicting potentially calamitous coastal and national impacts. (57 minutes)

Dr. Joseph Bookstein argues that the real cause of global warming is not the burning of fossil fuels but rather the needs and wants of the global human population, now over 6.6 billion. He discusses methods, feasibility, and implementation strategies for voluntary population reduction. (52 minutes)

Located in Newport, Oregon, Hatfield Marine Science Center plays an integral role in programs of marine and estuarine research and instruction, as a laboratory facility serving resident scientists, as a base for far-ranging oceanographic studies, and as a classroom for students. Site features information on courses, seminars, facilities, and current research. Education Programs section includes teacher and student resources. Resources applicable to local and distant educators.

In this video segment adapted from United Tribes Technical College, meet Native Americans who are concerned about climate change and believe that action today can help future generations once again live in harmony with Earth.
