4. Encouraging physical activity
In this unit, aimed at teachers of Physical Education, we begin by looking at some of the common misconceptions relating to fitness and activity levels together with accepted definitions of these concepts. We consider how active young people should actually be, and discuss how PE teachers can ensure they are making an effective contribution to this area of public health.

Voice-leading analysis of music 2: the middleground
This unit continues our examination of ‘voice-leading’ or ‘Schenkerian’ analysis, perhaps the most widely-used and discussed method of analysing tonal music. In this unit, this method is explained through the analysis of piano sonatas by Mozart. The unit is the second in the AA314 series of three units on this form of harmonic analysis, and concentrates on the ‘middleground level’ of voice leading. As you work through this unit, you will become familiar with the deeper levels of harm

This unit is the first in the MSXR209 series of five units that introduce the idea of modelling with mathematics. This unit centres on a mathematical model of how pollution levels in the Great Lakes of North America vary over a period of time. It demonstrates that, by keeping the model as simple as possible extremely complex systems can be understood and predicted.

Rainfall Accumulation from Hurricane Isabel (WMS)
Hurricane Isabel generated large amounts of rain over the Atlantic ocean as it approached East coast of the United States in September 2003. In fact, unlike many hurricanes, most of the Isabels rainfall did not occur over land; flooding on land was caused mainly by storm surge. This animation shows accumulation of rainfall from the hurricane--each frame shows the total amount of rain since the start of the measurement period. Rain from other sources has been masked out, so the hurricane track is

TOMS Ozone at the South Pole: October Averages from 1979 through 2000
The year 2000s Antarctic ozone hole is the largest ever observed. Scientists continue to investigate the phenomenon, and are somewhat surprised by its scale. Using data from NASAs Total Ozone Mapping Spectrometer (TOMS) instrument onboard the Earth Probe satellite, researchers can evaluate and compare current conditions over the south pole to readings taken by other instruments in years past. Continued monitoring of polar ozone levels helps researchers gain a better understanding of how the plan
