Packet of activities to assist in explaining solar and lunar eclipses, night and day, the four seasons and much more.
This lesson explores if it is normal that world temperatures are rising at the currently observed fast pace.
The purpose of this resource is to develop an understanding of some of the relationships between soils of different types and water. Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes through the soil and observing changes to the clarity of the water and to the characteristics of the soil. Students will be able to explore the concept of Earth as a system.
In this video from Science City, Kerri-Ann Richard, an environmental engineer, describes how she became interested in the field and why it is important to clean up the environment by removing contaminants from soil and ground water.
In this Nature video, follow geologists as they retrieve samples from a fresh batch of Kilauea's molten lava.
In this video segment adapted from NOVA, scientist Mike Garcia draws lava samples at the foot of the active Kilauea volcano to see if it is related to its neighboring volcano, Mauna Loa.
In this video segment adapted from the Alaska Native Heritage Center, discover the connections between Alaska Native subsistence culture and the natural cycle of the seasons.
In this adapted ZOOM video segment, cast members get hands-on in the recycling process by using old newspapers to make new paper.
In this video segment adapted from ZOOM, cast members make a seismometer and experiment with different ways to make it register movement.
In this video from the Science and Technology Chat series, take a tour of a re-created Nevada gold mine to learn about mining techniques.
In this video segment adapted from Hope in a Changing Climate, learn how an environmentally devastated ecosystem has been restored, benefiting both the local economy and global efforts to fight climate change.
This video segment adapted from NOVA relates the dramatic story of vulcanologists trying to predict the timing of the cataclysmic eruption of Mount Pinatubo in the Philippines.
This interactive activity adapted from A Science Odyssey Web site helps you visualize different types of plate tectonic activity and shows the impact this activity has on Earth's surface.
In this video from WOSU Columbus, learn about the types of communities of plants, animals, birds and fish that abound in wetlands.
Observe the Nisqually Glacier at Mount Rainier in this video segment from NatureScene.
Nitrogen, one of the most abundant elements in the universe, is essential to life. This interactive activity adapted from the University of Alberta provides an overview of the nitrogen cycle.
This brief video segment produced for Teachers' Domain features time-lapse video of a sunrise and a sunset.
This video adapted from KTOO explores the impact of oil contamination on the herring population of Prince William Sound, Alaska, in 1999, 10 years after the Exxon Valdez oil spill.
This video segment adapted from NOVA follows the clean-up effort after the 1989 Exxon Valdez oil spill off the coast of Alaska. Also featured is a marsh where an oil spill occurred 20 years earlier; analysis suggests that environmental damage may last for decades.
In this video segment adapted from the Yukon River Panel, visit fishing communities along the Yukon River and see how Alaska Native peoples exercise stewardship of salmon to ensure that it remains a central food source and cultural touchstone.
