Introductory advice
Global warming: are we responsible? Is our environmental impact damaging the planet? This unit examines the use of ozone depleting technology, the impact of fossil fuel use and explores how the development of technology can influence the direction of a society. From the Industrial Revolution to the present day find out how we have changed the planet.
1.1 Environment and technology
Global warming: are we responsible? Is our environmental impact damaging the planet? This unit examines the use of ozone depleting technology, the impact of fossil fuel use and explores how the development of technology can influence the direction of a society. From the Industrial Revolution to the present day find out how we have changed the planet.
Comparing modelled and observed temperature
This unit provides an introduction to global warming. We will be considering the history of global warming by looking at the pattern of ice ages and analyisis of recorded temperatures. We will aim to gather meaningful information from this data. We will briefly assess the impact and influence of humans on global warming and, finally, we will examine climate models and how to predict future changes.
4 The end of the last ice age: the Holocene
What affects the atmospheric and ocean flows? This unit explores the mechanisms that are important; the most rapid carrier is the wind. The basic principle of global atmospheric circulation is simple: warm air rises and cold air sinks. How does this principle affect the atmosphere and flow of water in practical terms?

Earth's physical resources: petroleum
The discovery of of the world's first major underground oilfield in Pennsylvania, USA in 1859 sparked the continuing era of the world's reliance on cheap energy from oil and gas. This unit begins by examining the geological characteristics of petroleum and the key ingredients necessary to form oil and gas accumulations. Then there is a brief description of industrial operations during the life cycle of an oilfield, starting with subsurface analysis and exploration drilling. The unit also highlig

Iraqis in Egypt: Time is Running Out
This documentary film looks at the lives of six Iraqi families who have been forced to flee their homes and are now living in Cairo. This documentary film looks at the lives of six Iraqi families who have been forced to flee their homes and are now living as refugees in the massive urban sprawl of Cairo. As the years pass by, their situations are becoming increasingly desperate, with little or no rights in their country of first asylum.
1.5.1 Juvenile survival
In this unit, we study one aspect of the fluctuating nature of an organism's environment. We consider how organisms living in a temperate climate, such as that in Britain, are adapted to cope with winter. You will see that there is much diversity of adaptations among organisms, with different species coping with the demands of a fluctuating environment in quite different ways. As cyclic variations are a widespread feature of environments, the range of adaptations to them is an important source o

Introduction
Genomes are composed of DNA, and a knowledge of the structure of DNA is essential to understand how it can function as hereditary material. DNA is remarkable, breathtakingly simple in its structure yet capable of directing all the living processes in a cell, the production of new cells and the development of a fertilized egg to an individual adult. DNA has three key properties: it is relatively stable; its structure suggests an obvious way in which the molecule can be duplicated, or replicated;
A World of Hurt. The true global death count of environmental degradation.
It's no secret that environmental degradation has been shown to have damaged people's health, often fatally, in many specific cases.
Now, however, world-leading research at the University of Adelaide has linked the two on a staggering global scale.
Learning outcomes
The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows.

Introduction
Water is arguably the most important physical resource as it is the one that is essential to human survival. Understanding the global water cycle and how we use water is essential to planning a sustainable source of water for the future. In the UK there area areas where water supplies are limited, shown by recent droughts. Globally, there are many areas that do not have enought water to support the currently population adequately. Decisions will have to be made on the best way to use water in a

5 chilly snowmen counting 1-5
Fun song for Christmas counting. This video will teach counting to 5 along with basic subtraction. A teacher's voice is singing in the background while the screen shows 5 snowmen on a felt board. Run time 01:55.
Energy Futures Lab Special Lecture - Powering the Planet
Professor Nocera describes science's greatest challenge to find secure, sustainable and environmentally responsible ways to meet the dramatic increase in global energy consumption.
2.5 Nicolas Malebranche and George Berkeley
Part 2.5. Focuses on Malebranche, a lesser-known French Philosopher, and his ideas on idealism and the influence they had on English philosopher George Berkeley.
