Homogenization of northern U.S. Great Lakes forests due to land use
Human land use of forested regions has intensified worldwide in recent decades, threatening long-term sustainability. Primary effects include conversion of land cover or reversion to an earlier stage of successional development. Both types of change can have cascading effects through ecosystems; however, the long-term effects where forests are allowed to regrow are poorly understood. We quantify the regional-scale consequences of a century of Euro-American land use in the northern U.S. Great Lak
HIV/AIDS Education in America (MWV14)
In this episode of MicrobeWorld Video we ask some leading researchers, education specialists, and public health officials about the state of HIV/AIDS education in America and ideas they have to support the teaching of microbial evolution using the latest HIV/AIDS research all while instilling innovative prevention strategies. Filmed at a forum for educators on February, 11, 2008 at the Koshland Science Museum in Washington, D.C. and at San Diego State University, this episode features the follow
Enhancing Your Biology Course and Lab WWW Pages with the Latest in HTML, CGI, and JavaScript Feature
This workshop directed at individuals with basic htm and web page construction experience, demonstrates how to enhance your course webpages. We will demonstrate techniques in a platform independent manner such that you can add tutorials, quizzes, embedded sound, video, image maps and JavaScript to your course homepages. We will discuss the potential and limitations of enhanced webpages and the basic differences between the Internet and your own campus Intranet. We will show how to optimize your
Electron Flow in Photosynthesis
The fascinating concept of electron flow is explored with simple equipment in an exercise for first-year students. Students use a spectrophotometer to generate an absorption spectrum for spinach chloroplasts, and then make a prediction about the effect of wavelength of light on the rate of photosynthesis. Students design their own carefully controlled experiments to test their predictions.
Lunar Lollipops
The students work in teams of two to discover the relative positions of the Earth, Sun and Moon that produce the different phases of the Moon. The students will be given a Styrofoam ball that they will attach to a pencil so that it looks like a lollipop. This ball will be the Moon, the students will be the Earth and a hanging lightbulb will be the Sun. The students will move the "Moon" around them to discover the different phases. They will fill in the position of the Moon and its corresponding

4.2.5 Focusing
BBC News 24, Sky News, CNN – we live in an era where news has become almost instantaneous. This unit will look at how news is gathered and the technology used for its dissemination. You will also be encouraged to examine how information might be manipulated by questioning its reliability.
Earth Today 1998 Countdown
The ability to see Earth from space has forever changed our view of the planet. We are now able to look at the Earth as a whole, and observe how its atmosphere, oceans, land masses, and life interact as global systems. Earths atmosphere, hydrosphere, geosphere, and biosphere are dynamic, changing on timescales of days, minutes, or even seconds. Monitoring the Earth in near real time allows us to get an up to date picture of conditions on our planet. More SVS visualizations for the Earth Today ex
Urban Signatures: Sensible Heat Flux (WMS)
Big cities influence the environment around them. For example, urban areas are typically warmer than their surroundings. Cities are strikingly visible in computer models that simulate the Earths land surface. This visualization shows sensible heat flux predicted by the Land Information System (LIS) for a day in June 2001. Sensible heat flux is higher in the cities--that is, they transfer more heat to the atmosphere--because the surface there is warmer than in the surroundings. Only part of the g

Strum Along
Music and sound are two different concepts that share much in common. Determining the difference between the two can sometimes be difficult due to the subjective nature of deciding what is or is not music. The goal of this activity is to take something constructed by students, that would be normally classified as just sound and have the class work together to make what can be perceived to be music. Students will construct a basic stringed instrument made of a shoebox and rubber bands. This activ

3.1 Exploring your personal ecology
There is increasing recognition that the reductionist mindset that is currently dominating society, rooted in unlimited economic growth unperceptive to its social and environmental impact, cannot resolve the converging environmental, social and economic crises we now face. The primary aim of this unit is to encourage the shift away from reductionist and human centred thinking towards a holistic and ecological worldview.

1.11 Summary
Have you ever wondered how scientists analyse the environment? This unit introduces you to the techniques used by science students at residential schools. You will learn how to determine where rocks have come from and how they were made. You will also examine the processes involved in determining the ecology of a particular area.

Plausible? Journeying Through Space and Time in a Wormhole
Journeying Through Space and Time in a Wormhole - Professor Ian Morison discusses time, one of the most mysterious concepts in our Universe. It is easy to describe how we define its passage and how we can make exceedingly accurate clocks but questions as to what determines the arrow of time and whether time travel is possible can tax the most brilliant minds!
