This is the story of studying Mars on Earth at Devon Island, the largest uninhabited island in the world located 500 kilometres southwest of the Magnetic North Pole. Devon Island is an analogue to Mars which has made it extremely interesting to NASA. Mars on Earth follows the largest scientific mission on Earth known as the NASA/Haughton-Mars Project. With exclusive access, we follow Dr. Pascal Lee and his team of 60 scientists in their exploration of Mars on Earth.

Arctic Diamond Fever
This is the story behind the multibillion dollar fever that has led internationally renown geologists to the most unlikely place on earth – a land package the size of Texas in the empty, remote and vast barren lands of the Artic. Fueled by the fever of the hunt for that rare and precious find and in spite of deathly obstacles, geologists began what has become the biggest staking rush in world history. This is the search for the oldest, hardest, and most valuable gem in the world.

Climate Change: Our Responsibility
This program establishes the vital importance of the greenhouse effect for life on Earth and then presents a balanced argument to assess whether or not anthropogenic climate change (often called global warming) is in fact taking place. Clear arguments are presented on both sides of the debate and illustrations given covering both more economically developed countries and less economically developed countries, with impacts and responses fully explored. A thorough and balanced examination of this important and often contentious issue.

Renewable Fuels
Traditionally we have relied heavily upon non-renewable energy resources, however we have now reached a tipping point globally where the environment cannot sustain such impact, nor do we have the resources to continue this. This program clearly shows the environmental impacts of both renewable and non-renewable energy sources. It guides us through numerous renewable energy sources, how the energy is collected and the pros and cons of renewable energy. The program also explores what is happening around the globe with the introduction of wind farms, wave parks and solar farms. This is an up-to-date look at a vital issue.

The Greenhouse Effect: Climate Change and Global Warming
What exactly are greenhouse gases? Are they really causing climate change? Global warming has suddenly become the hottest environmental issue, and this program clearly explains the science of greenhouse effect and the evidence that we are causing climate change. The DVD contains an advanced version for senior students, with in-depth analysis of greenhouse gases and their effects. In addition there are fascinating extras including ice core research in Antarctica, how warming threatens coral reefs, and how carbon capture and storage work.

Waves in the Ocean (Senior)
This is a remake of the best-selling 1985 video of the same name. Updated with graphics/animation, exciting new footage and a specific science/physics focus, this film provides an excellent summary of the nature of waves, as illustrated by waves in the ocean. Topics covered include: how waves are formed by the wind; elliptical paths of water particles in a wave; wave characteristics – amplitude, wave height, wavelength, period, speed, frequency; interference; reflection; refraction; diffraction; translatory waves; why & how waves break.

Waves in the Ocean (Junior)
An inspirational film showing the beauty and order behind the movement of the ocean wave. Topics include how waves are formed by the wind; eliptical paths of water particles in a wave; reflection off cliffs; bending by shallow water; sets; how to catch a wave.

River Landforms
Using examples from around the world, this video looks in detail at the landscapes and features along the courses of rivers, examining the processes that have shaped them over thousands of years. Topics include : sources of rivers, erosion, transportation, deposition, drainage basins and patterns, flood plains, levees, terraces, meanders, sandstone, granite and limestone landforms.

Rainforests
Presented by Richard Morecroft, this video is an excellent introduction to rainforests, providing information on their nature and structure and the role of light, water, soils, fauna, and vegetation in a rainforest. The video concludes with ideas that summaries the main points of view about logging rainforests, leaving viewers to develop their own opinions.
