This ZOOM video segment shows how to create a self-contained environment and explores evaporation, condensation, and precipitation.

This interactive resource adapted from NASA describes the different temperature, precipitation, and vegetation patterns in seven biomes: coniferous forest, temperate deciduous forest, desert, grassland, rainforest, shrubland, and tundra.

Students are introduced to the concepts of biomimicry and sustainable design. Countless examples illustrate the wisdom of nature in how organisms are adapted for survival, such as in body style, physiological processes, water conservation, thermal radiation and mutualistic relationships, to assure species perpetuation. Students learn from articles and videos, building a framework of evidence substantiating the indisputable fact that organisms operate "smarter" and thus provide humans with inspiration in how to improve products, systems and cities. As students focus on applying the ecological principles of the previous lessons to the future design of our human-centered world, they also learn that often our practices are incapable of replicating the precision in which nature completes certain functions, as evidenced by our dependence on bees as pollinators of the human food supply. The message of biomimicry is one of respect: study to improve human practices and ultimately protect natural systems. This heightened appreciation helps students to grasp the value of industry and urban mimetic designs to assure protection of global resources, minimize human impact and conserve nonrenewable resources. All of these issues aid students in creating a viable guest resort in the Sonoran Desert.

How can you tell if harmful bacteria are in your food or water that might make you sick? What you eat or drink can be contaminated with bacteria, viruses, parasites and toxins—pathogens that can be harmful or even fatal. Students learn which contaminants have the greatest health risks and how they enter the food supply. While food supply contaminants can be identified from cultures grown in labs, bioengineers are creating technologies to make the detection of contaminated food quicker, easier and more effective.

This article continues an examination of each of the seven essential principles of the climate sciences on which the online magazine Beyond Weather and the Water Cycle is structured. Principle 3 states that life on Earth depends on, is shaped by, and affects climate. The climate dictates where and how species can survive. The author discusses the scientific concepts underlying the life forms' dependence on the climate and expands the discussion with diagrams, photos, and online resources.

MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with videocameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch "gaaaa" slowly turn into "water." Astonishing, data-rich research with deep implications for how we learn. Deb Roy studies how children learn language, and designs machines that learn to communicate in human-like ways. On sabbatical from MIT Media Lab, he's working with the AI company Bluefin Labs. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 20-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

Plumbing Apprenticeship Program Level 3

Short Description:
The content of this block is organized to introduce the plumber apprentice to the theory and installation of potable water systems and landscaping irrigation systems. Providing safe potable water is one of the major responsibilities for plumbers and this block will cover the design and installation of piping from the available water service to point of use. Water used for landscaping will also be addressed with a focus on a balanced approach to the design, use, and safety of a residential automatic irrigation system.

This activity provides instructions for using a flashlight and aquarium (or other container of water) to explain why the sky is blue and sunsets are red. When the white light from the sun shines through the earth's atmosphere, it collides with gas molecules with the blue light scattering more than the other colors, leaving a dominant yellow-orange hue to the transmitted light. The scattered light makes the sky blue; the transmitted light makes the sunset reddish orange. The section entitled What's Going On? explains this phenomena.

This resource was created by Janis Nicholas, in collaboration with Lynn Bowder, as part of ESU2's Mastering the Arts project. This project is a four year initiative focused on integrating arts into the core curriculum through teacher education and experiential learning. 

This lesson contains videos, slides, and assignments for students that learning about the different bodies of water and the different forms of water. 

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Bogs are unique ecosystems, which have important ecological functions in carbon storage, climate stability, water quality, and biodiversity. The bog microbiome, composed mostly of bacteria that live in association with bog plants, plays key roles in these functions. However, the differences in associated bacteria between vascular plants and the non-vascular bryophytes that predominate in bogs remain unclear. Researchers recently used shotgun metagenomics to investigate the microbes associated with 12 representative bog species. Vascular plants tended to be colonized by specific bacteria, while bryophytes exhibited greater bacterial species richness and diversity. The two plant groups also had different marker species. The gene profiles of vascular plant- and bryophyte-associated microbes revealed functional differences, including differences in nitrogen cycling..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This guided inquiry activity, in which ice is used to boil water in a Florence flask, works well in the introductory class to a chemistry or physical science course. The students will learn the difference between observation and inference and apply this understanding to various other situations in which observations and inferences must be made. The students will also use outside sources to try to explain why the activity worked.

The repercussions of the Great Migration are far-reaching. Today, much of the restlessness and struggle that the Blues helped to articulate in the Migration era remains central in other forms of American music, including Hip Hop. In this lesson, students look to Muddy Waters and Howlin' Wolf as case studies that illustrate why African Americans left the South in record numbers and how communities came together in new urban environments, often around the sound of the Blues.

This lesson investigates how electrifying the guitar was a contributing factor to the emergence of a sound that came to define Rock and Roll and, to a large extent, mid-20th century American popular culture. Featuring content from the PBS Soundbreaking episode, "Going Electric," which includes the guitar playing of luminaries Charlie Christian, Pete Townsend, Muddy Waters and Jimi Hendrix, this lesson examines the spirit of curiosity, adaptation and invention that characterized the early 1950s and in the 1960s led to the guitar's emergence as a versatile and attractive instrument for musicians and as the quintessential Rock and Roll icon.

In this lesson, students listen to Flint-based rapper Jon Connor's song "Fresh Water for Flint" to better understand the sense of frustration and injustice people living in the city felt during the water crisis. Students then experiment with creating their own water filtration system to better understand the scientific and engineering principles behind water treatment. Lastly, they consider the biological effects of lead poisoning and determine specific, political, economic, and scientific causes behind the Flint water crisis.

Question Let's suppose that you have a shoe box full of water (the box is waterproof, of course). The shoe box weighs about 9 kg (19.8 pounds). Suppose you emptied the box and filled it completely with rock (little or no air space). How much would it weigh? Let's empty the box again and fill it completely with pure gold. How much would the box weigh now?

Here’s a new “spin” on an old toy. In this modern adaptation of a classic toy—the spool racer—a plastic water bottle is propelled by energy stored in a wound-up rubber band.

In the activity students learn about the properties of solutions, acidity and pH, electrolytes versus non-electrolytes, and solution concentration. Hopefully, this activity will also dispel common misconceptions about tap water and bottled beverages.
