This teaching activity addresses environmental stresses on corals. Students assess coral bleaching using water temperature data from the NOAA National Data Buoy Center. Students learn about the habitat of corals, the stresses on coral populations, and the impact of increased sea surface temperatures on coral reefs. In a discussion section, the connection between coral bleaching and global warming is drawn.

Educators can use the resources in this Collection to teach their students about the science and beauty of corals. They can use these organisms and ecosystems to teach many scientific concepts including symbiotic relationships, reproduction strategies, food webs, chemistry, biotic and abiotic interactions, human impacts, etc. Additionally, educators can use corals to teach about conservation and stewardship of the environment. Even if you don't live near a reef, students can learn that they can help protect coral reefs in the U.S. and around the world. There are many actions, small and large, that you and your students can take to help conserve coral reefs.

A Day in the Life of a Drop is a set of activities designed to help students in grades 3-5 understand the connections between the source of the water they use and the ways their water use habits affect the environment and human health. Students also learn how to reduce their impacts and engage family members. After completing the worksheets provided, students and families take the Pledge to Filter Out Bad Water Habits to demonstrate their commitment to saving water for the future.

Hypoxic zones are areas in the ocean of such low oxygen concentration that animal life suffocates and dies, and as a result are sometimes called "dead zones." One of the largest dead zones forms in the Gulf of Mexico every spring. This data visualization discusses the causes of hypoxia in the Gulf of Mexico.

This interrupted case study focuses on the seasonal hypoxic area in the Gulf of Mexico known as the Dead Zone. It follows Sue, a college student, whose father is a commercial fisherman affected by the lack of fish in his usual fishing grounds in the summer. In her quest to determine why the fish disappear, Sue learns about both the biological and physical forces that produce, maintain, and eventually dissipate the hypoxic zone. The case introduces students to the marine food web, the aquatic microbial loop, the impact of exogenous nutrients, and the physical forces that affect oxygen content and water stratification. It could be used in introductory biology or ecology courses or in an oceanography course.

Decomposers eat and break down dead organic material and release nutrients into the soil. Decomposers help in nutrient cycling because they release atoms, which are then recycled in the environment (soil, air, water). Decomposers range from obvious earthworms to non-obvious microscopic microbes and bacteria.

- Abstract:

Drought affects humans, animals, and plants. Humans can change the course of the water cycle, to some extent, to meet their needs, but can they do so without imposing risks on the plants and animals? As urban areas continue to grow, policy makers must plan for potential water shortages, taking into account competing interests for water.In this lesson, students will look at drought from a variety of perspectives. The lesson focuses first on the scientific definition of drought, including weather patterns, water cycles, water requirements by plants and animals, and physiological responses by plants and animals to drought. The lesson also focuses on the current and historic social and economic impacts of drought.

- Abstract:

" Water supply is a problem of worldwide concern: more than 1 billion people do not have reliable access to clean drinking water. Water is a particular problem for the developing world, but scarcity also impacts industrial societies. Water purification and desalination technology can be used to convert brackish ground water or seawater into drinking water. The challenge is to do so sustainably, with minimum cost and energy consumption, and with appropriately accessible technologies. This subject will survey the state-of-the-art in water purification by desalination and filtration. Fundamental thermodynamic and transport processes which govern the creation of fresh water from seawater and brackish ground water will be developed. The technologies of existing desalination systems will be discussed, and factors which limit the performance or the affordability of these systems will be highlighted. Energy efficiency will be a focus. Nanofiltration and emerging technologies for desalination will be considered. A student project in desalination will involve designing a well-water purification system for a village in Haiti."

Sand covers only about 20 percent of the Earth's deserts. Nearly 50 percent of desert surfaces are gravel plains where removal of fine-grained material by the wind has exposed loose gravel and occasional cobbles. This web page, produced by the U.S. Geological Survey, features text and photographs that describe desert landforms, soils, plants, and the role of water in the formation of desert landscapes.

This OLogy activity, a hide-and-seek game, introduces kids to the many different ecosystems in the ocean. The activity opens by telling kids that the ocean is made up of many different communities called ecosystems, and that all living things in an ecosystem depend on each other. Then, in the Think and Link game, kids are challenged to connect all the featured organisms in three ecosystems.
