In this lesson, students will work in teams to do further research on the ethics issues presented in the documentary The Nobel: Visions of Our Century.
Biotic Indices of Stream Macroinvertebrates for Fun and (Educational) Profit
Water quality monitoring activities can support student inquiry into ecological concepts and pollution issues, as well as offer insight into integrating field and lab work. This exercise provides students with practice in identification (to order or family level) of stream macroinvertebrates that they've previously collected. Provided information indicates water pollution tolerance of the various taxa. Students use the data to calculate several different biotic indices for the macroinvertebrates
Investigating Fungi Which Cause Rot and Decay
The fungi which cause rot and decay in our forests are vital members of the ecosystem. By decomposing the hard woody stems of trees they help recycle important nutrients, minerals, and carbohydrates. Unlike many organisms which are easy to see, the fungi are often hidden under bark or within living stems and their presence is not obvious. This laboratory exercise provides instructors with information about where to find and how to visualize and manipulate fungi which cause rot and decay, while d
Lennox Castle Hospital
This unit looks at the history of institutions in the twentieth century, starting with a case study of Lennox Castle Hospital. It tries to make sense of the history of Lennox Castle, and of institutional life in general, through testimony of those who experienced institutions as inmates and as nurses, as well as through Erving Goffman's model of the 'total institution'. It examines the social bases of segregation, the professionalzsation of staff in asylums and institutions, and campaigns for ch
Gravitropism is the turning or growing in a different direction of a plant in response to gravity. This plant's shoots grow upward and exhibit negative gravitropism because they are growing away from gravity's pull.
Celery in pure water
The celery stalks take up the water and continue to live in this environment.
Roots can grow in multiple directions. Just because this plant was in a cup didn't stop the roots from growing longer and creating individual branches.

Safari 2000 Tropospheric Ozone
The fires that raged across southern Africa in August and September of 2000 produced a thick river of smoke that observers compared with the aftermath of the Kuwaiti oil fires in 1991. NASA-supported studies currently underway on the event will contribute to improved air pollution policies in the region and a better understanding of its impact on climate change.
EPTOMS Ozone (7-26-96 - 12-4-00)
This animation shows the total ozone as measured by Earth Probe TOMS since the earliest measurements by that instrument. Days on which no data was taken appear as blank.
North America NDVI 1993 August
NDVI in North America for August 1993, based off data collected over the 1981-2000 time frame.
Ozone Layer Shielding Our Planet
An animation showing the ozone layer shielding our planet from the suns intense ultraviolet radiation. Ozone absorbs nearly all of the biologically damaging UV radiation from the sun.
Digital Earth Workbench: 3D Hurricane Luis
The Digital Earth Workbench is an interactive application that runs on a SGI Onyx Infinite Reality system and is controlled by an Immersive Workbench, tracked stereo glasses, and a tracked wand. The application allows an unprecedented freedom to roam georeferenced datasets at multiple resolutions and timescales. This animation is one of a series of direct screen captures of the application in operation. The occasional menu appearance denotes direct intervention by the operator to add or delete d

Total ozone measurements from Earth Probe TOMS over Antarctica for the period July 25, 1999 through September 25, 1999
Science of Sound
Welcome to Science of Sound. This course is offered as a regular class Fall Semesters on the USU campus in Logan, Utah. It is also available over the internet Fall, Spring, and Summer semesters, or as a yearlong independent-studies course. In each case, work is submitted using the internet. The only difference in the regular class held Fall semester is that students meet with the professor three times a week to discuss the material in the text. A teaching assistant is assigned to answer question
