Ecology is the study of how living things interact with each other and their environment. This includes living things (biotic factors) and non-living things (abiotic factors).
Introduction to ecosystems. How land ecosystems are classified into biomes.
In this video produced by ThinkTV, explore the effects of land masses on local climate conditions, and learn about regional impacts of land-atmosphere interactions.
In this video segment adapted from NOVA scienceNOW, scientists examine the link between rising sea surface temperature and more intense hurricanes.
In this media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.
Scientists discuss whether or not endocrine disrupting chemicals, which may cause birth defects and other health concerns, should be controlled in the absence of conclusive proof, in this video segment adapted from FRONTLINE: Fooling with Nature.
Watch students as they conduct an energy audit on a home and gain hands-on experience for a career in the green energy industry, in this video adapted from ATETV.
This feature, adapted from Interactive NOVA: "Earth," follows the path of energy as it is transferred via the food chain from one type of organism to another.
This video segment, adapted from NOVA, describes the energy flow in a coral reef, including its food web.
Students explore the biosphere and its associated environments and ecosystems in the context of creating a model ecosystem, learning along the way about the animals and resources. Students investigate different types of ecosystems, learn new vocabulary, and consider why a solid understanding of one's environment and the interdependence of an ecosystem can inform the choices we make and the way we engineer our communities. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
In this adapted video segment, ZOOM guest Tommy takes us on a tour of the Florida Everglades. He describes what makes a wetland biome unique, including the soil, precipitation, and biodiversity.
Example identifying roles in a food web.
Learn about population growth rates and how they can be modeled by exponential and logistic equations.
Species extinction is happening at an alarming rate according to scientists. In this lesson, students are asked to consider why extinction is a problem that we should concern us. They are taught that destruction of habitat is the main reason many species are threatened. The lesson explores ways that engineers can help save endangered species.
In this video segment adapted from Interactive NOVA, astronaut John Young experiences extreme temperatures on the Moon that are a result of the Moon's low gravity and lack of atmosphere.
In this video from Common Ground and Cleaner Water, Tribby Vice, a Kentucky farmer, talks about the changes he has made on his farm to protect the water quality of the stream running through his property and the watershed in which he lives.
In this video segment adapted from NOVA scienceNOW, scientists in western Greenland explain how a glacier there is shrinking and moving faster due to increased melting.
This video segment from the teacher video series Learning That Works uses a case study to highlight the effectiveness of a project-based, real-world approach to teaching science.
In this video segment adapted from NOVA, scientists investigate how farming along the Mississippi River impacts floods and what can be done about it.
This video segment from NatureScene features the area of the Congaree Swamp where the high ground and the flood plain meet. Learn how a few feet of difference in elevation on a floodplain can yield drastic changes in what youŰ__Ű__Çll find living there.
