Students will add acidity to a healthy lake to see what happens to plants and animals in this interactive activity adapted from EcoKids.
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
This site from the Environmental Education for Kids contains colorful and detailed information on water resources. Site covers fascinating tips and facts, as well as engaging quizzes on the wonderful world of water. Best suited for grades 3-6.
Use this student portal to understand all you can about acid rain and its harmful effects. Modules for interactive games, stories, puzzles, vocabulary terms and links to other activities and experiments.
Market-based regulatory programs designed by the EPA, with information for consumers and industry cap-and-trade policies, Clean Air Act, and other government-sponsored efforts to reduce air pollution.
Air pollution occurs both inside and outside and is dangerous to individuals as well as to the planet. The Environmental Protection Agency oversees laws and regulations related to air quality and has gathered a wealth of information to help individuals understand the issue and address air pollution problems.
This 27-page booklet explains the Clean Air Act using everyday English.

This activity is an in class lab where students will compare different acid solutions on seed germination and growth.
Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through multiple topics and activities, students see how electricity and magnetism are interrelated.
This hands-on activity explores five different forms of erosion (chemical, water, wind, glacier and temperature). Students rotate through stations and model each type of erosion on rocks, soils and minerals. The students record their observations and discuss the effects of erosion on the Earth's landscape. Students learn about how engineers are involved in the protection of landscapes and structures from erosion. Math problems are included to help students think about the effects of erosion in real-world scenarios.
Through an overview of some of the environmental challenges facing the growing and evolving country of China today, students learn about the effects of indoor and outdoor air pollution that China is struggling to curb with the help of engineers and scientists. This includes the sources of particulate matter 2.5 and carbon dioxide, and air pollution impacts on the health of people and the environment.
The goal of this activity is to understand how techniques of persuasion (including background, supporting evidence, storytelling and the call to action) are used to develop an argument for or against a topic. Students develop an environmental case study for presentation and understand how a case study is used as an analysis tool.
Learn about some sources of outdoor air pollution.
