This video provides history on product development by General Motors and other industries that led to the release of Chlorofluorocarbons (CFCs). It explains the connection between global warming and the ozone hole, chemical build-up in our lower and upper atmospheres, the increase in GWP gases, increased air quality ozone alerts and the 1987 Montreal Protocol that banned the use of CFCs globally.

Human Resource Development (HRD) is a practice that combines training, organization development, and career development efforts to encourage the improvement of individual, group, and organizational performance. Often confused with Human Resource Management (HRM), this video discussed the four basic sections of HRD.

This animation starts with a schematic illustration of glacier growth and then introduces six different methods that researchers use when studying ice cores in order to deduce the climate of the past. The research methods that are briefly introduced are ice layering, pollen, oxygen isotopes, ice crystals and gases trapped inside, and other chemistry.

This video, video transcript, and accompanying poster, go beyond a description of weather and climate to highlight how NASA tracks the changes in climate and why it matters. Students will leave the video with the important sense of why data (in this case, gathered by satellites) is helping all of us monitor sea level, clouds, and to know that the earth's climate is getting warmer.

In this video you learn what happens when a Beluga whale, normally found far north in the arctic, suddenly shows up in a Bay in Nova Scotia? What happens when she starts swimming with people and approaching boats full of tourists? This segment shows how one incredible friendly whale transformed a town, and captured the hearts of children and adults alike. Please see the accompanying study guide for educational objectives and discussion points.

Windmills have been used for hundreds of years to collect energy from the wind in order to pump water, grind grain, and more recently generate electricity. There are many possible designs for the blades of a wind generator and engineers are always trying new ones. Design and test your own wind generator, then try to improve it by running a small electric motor connected to a voltage sensor.

They have big, sharp teeth, long eel-like bodies, and they look like they could bite your fingers right offŰÓbut Jonathan can pet them. TheyŰŞre Wolffish, and in this video Jonathan visits both Atlantic and Pacific species. You wonŰŞt believe the amazing encounters he has with these friendly but mean-looking fish. Please see the accompanying study guide for educational objectives and discussion points.

Material created for an exhibition curated by the University of Tennessee at Chattanooga Special Collections.
Since 1886, there has been a library serving the University of Tennessee at Chattanooga campus and metropolitan area. As the campus has grown and changed over the years, so too has the library, responding to the needs of the university. Although many of the library resources available to current students, faculty, staff, and community members look different than those of years past, this exhibition celebrates the library’s commitment to supporting information discovery and providing infrastructure for learning that have been a part of its mission from day one.

Interactive hx diagram (Mollier) for displaying the changes in state of humid air at sensible temperature change, wet cooling, mixture air, humidification and custom state points. Automatic calculation of the required heat flow for cooling and heating. Free online tool, no registration required.
More detailed information: To analyze changes of state of moist air normally a diagram with the specific enthalpy as the ordinate and the humidity ration as the abscissa is used. This specific type of diagram was proposed in 1923 by the German professor of applied physics and mechanics, Richard Mollier. The Mollier diagram is respectively created for a certain constant pressure, usually the atmospheric pressure (p≈1bar). The thermodynamic properties of moist air are represented in the state diagram as lines of constant state variables - so-called isolines.
