Short AMERICAN EXPERIENCE video tells the story of how environmentalists, Alaska Native peoples, and engineers concerned about the effects of permafrost challenged plans for the Alaska oil pipeline. [5:19]
This video segment from Wild Europe: "Wild Arctic" explores the struggle for survival in one of Earth's most extreme environments.
In this lesson, students will learn about rondo form and practice a chant. After learning about the structure of the chant, they will work in small groups to create a chant about a habitat. The chants will then be combined with the model chant to create a rondo form.
How do ecosystems work, and how can understanding them help us protect them? In this unit, students investigate the 30 by 30 initiative, a proposal to protect 30% of US lands and waters by 2030, and the reasons humans engage in conservation. Students use the Serengeti National Park as a case study to figure out ecosystem and conservation principles and apply those understandings to conservation dilemmas in the US.
OpenSciEd content is highly rated in EdReports and is aligned to NGSS standards.
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 focuses on the four foods most important to the grizzly bears' survival, and it describes the threats to the supply of each of them.
In this video segment from Nature, learn about the problems bears are creating on ranch land surrounding Yellowstone National Park.
Students will create a food chain model and use it to describe the movement of matter among plants, animals, decomposers, and the environment. Resources include a detailed lesson plan, student handouts, pictures of a completed chain, examples of student work, and a video of the lesson in action.
Students will build a food web diagram and illustrate the movement of matter through a series of food chains. Resources include detailed plans, examples of student work, videos of the lesson in action, and sample food webs.
In the following video students will learn how the environment impacts human health and the ecosystems around us, on both a small/local and large/global scale. [15:42]
This video segment from Evolution: "Extinction!" shows the impact of invasive species on native ecosystems.
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.
By the end of this section, you will be able to do the following:
Discuss the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfur
Explain how human activities have impacted these cycles and the potential consequences for Earth
By the end of this section, you will be able to do the following:
Describe the basic ecosystem types
Explain the methods that ecologists use to study ecosystem structure and dynamics
Identify the different methods of ecosystem modeling
Differentiate between food chains and food webs and recognize the importance of each
By the end of this section, you will be able to do the following:
Describe how organisms acquire energy in a food web and in associated food chains
Explain how the efficiency of energy transfers between trophic levels affects ecosystem structure and dynamics
Discuss trophic levels and how ecological pyramids are used to model them
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
This comprehensive study guide covers the main terms and concepts needed for a unit on biomes.
