This program explores natural forces inside our planet, how and why earthquakes occur, the 2004 tsunami and the international response that followed. Senior seismologist Gary Gibson takes us through some reasons why the earth has such destructive potential, and the natural forces behind the 2004 tsunami. Featuring a range of natural disaster footage, graphics, footage of the tsunami aftermath, and interviews with aid workers involved in the international response.
Join environmental engineer Will Toliopoulos as he takes us into the field to explore the rock cycle. We begin with a tour of Earth's core, mantle and crust, and how they interact to form the three main types of rock - igneous, sedimentary, and metamorphic. Next is a detailed exploration of the three rock types, how they are formed, their properties, structure and characteristics. And finally there is the rock cycle itself, here explained in detail using real-life examples and dynamic graphics. Our youthful presenter clearly explains concepts and defines key terms while keeping this complex topic fresh and interesting.
It affects everything we do, from our day to day plans of what clothes to wear to affecting the way we feel. Weather is a giant continuum of change and is crucial to the planet's survival. But how is it measured and why is it sunny one day and raining the next? This Australian-made, curriculum fit program explores what is weather and how is it measured; how do we forecast weather; weather warnings and finally the global climate. Including interviews from key senior personnel at the Bureau of Meteorology this program gives excellent insight into the recording and forecasting of weather.
Take a ride with a storm chaser and follow a twister, then create one yourself on a kitchen counter. What makes Tornado Alley perfect for tornadoes to form?
Pluto is the first of the dwarf planets. We learn why Pluto has been declassified as a "regular" planet. Find out what these strange icy worlds are like in the darkness of deep space.
It could happen any time! But don't worry, we now have ways to see them coming. Our Host Bob shows how scientists are working to prevent asteroids from hitting us.

Travel more than two kilometers underground and see how scientists are trying to capture mysterious dark matter and dark energy, which make up more of the universe than stars and planets.
From the tap in your own home to the mighty Amazon River, humans often use water without really thinking where it has come from or where it is going to. Such a precious resource is often taken for granted and this program looks at how we use and dispose of water in our homes, in industry and on the land. The conservation and regulation of water is a topic that is evolving daily and is not restricted by political boundaries. From individuals to national and international governments, the natural resource of water is something we all must help manage.
Watch as astronauts train for a space mission. Learn how to make dinner on the Space Shuttle. Pay a visit to Space Camp and the International Space Station.
Through dramatisation and animated graphics, this program clearly explains current theories regarding the structure of the Earth, and how the continents came to be in their current positions. It explores the history behind the widely accepted theory of Tectonic Plates, involving Continental Drift and Sea Floor Spreading, and then examines the alternative theory of Global Expansion. Featuring a range of geological evidence, expert opinions and even a trip back in time to visit Galileo Galilei at his home in Florence, this program looks at how once hotly-disputed ideas can become accepted as scientific fact.
Our appetite for the earth's resources and consumer goods has led to increased levels of carbon dioxide entering our atmosphere, trapping more heat from the sun and leading to global warming of the atmosphere.
This program argues that action could and should be taken at both international and political levels, then addresses the question of what each of us as individuals can do to reduce our use of non-renewable energy sources and lower our personal 'carbon footprint' on the planet.

Why does the sun rise in the east? Why does the moon change shape? How do tides happen? This program explains in detail how the Earth and the Moon move with respect to each other and the Sun, why we have day and night and different time zones. Why we have four seasons every year, two tides and the different phases of the moon. This program will enhance student understanding of key concepts that are effectively demonstrated through clear graphics and animation.
Australia's diverse landscape and climate has always been subject to many environmental hazards. Using case studies of cyclones, floods and droughts, this program demonstrates how property can be protected and lives saved with well-coordinated disaster management plans. The program highlights the measures that should be taken by government and non-government organisations, as well as on the individual level, in order to prepare for and respond to a natural disaster. Warning: The program features a brief scene of an animal being shot.

The coast plays a large part in the lives of most Australians, yet it is also a resource that is under-appreciated and often torn between bureaucracies. In this program we talk to some of Australia's leading coastal experts about the numerous values of the coast, how beaches are formed, the range of habitats that are a part of the coast, the major uses, impacts and threats and the levels of governance that shape our coast.
Renewable energy offers a long term solution to the problems caused by our use of fossil fuels, but if we want to make an immediate impact, the best place to start is energy conservation. Developed countries like Australia have relied on cheap energy to maintain high living standards, but this has produced a culture of wastefulness and inefficiency. This program takes the audience on a tour of an energy efficient house to show how the average home can cut energy use. And to make sure the audience identifies with the subject, we also visit an average Australian household and an average Australian secondary school, to see what they've done to conserve energy. Once people are educated about the way we use energy, they realise how easy it is to make the small changes that are needed to cut our energy use. This program shows that this results in big savings on our energy bills and makes a significant contribution to the health of our planet.
This program profiles examples of technologies harnessing renewable energy - such as a wind farm, a bus running on ethanol, and a solar house - and uses these examples to examine the current state of renewable energy in Australia. Some sources of renewable energy, such as the wind industry, are amongst the fastest growing industries in the world! The program is an entertaining and informative guide to an extremely important issue for the future of our planet.
A primary producer of peaches in Shepparton discusses diversified farming and growing conditions including the need for irrigation and subsequent environmental considerations. We investigate the climate needs, weed and pest control, water management, and the re-use of factory waste. In Lismore we talk to a macadamia producer about his farming operations, processing and value-adding as well as integrated pest management, soil erosion controls, conflict with urban encroachment, and factory noise and waste controls. Seasonal work and noise pollution are also covered as we follow the products from the farm to the factory to our tables at home.
Describing the greenhouse effect in detail and following the "Classical Science" processes of observation and description, we see the search for regularities and connections between data and the formulation of probable explanations for why connections exist. Testing these "most probable explanations" is frequently done using computer models and the program describes how simple mathematical models have developed into remarkably useful predictive tools. Topics covered include: observation of the past temperatures of the earth (using oxygen isotopes in ice cores) and the present quantity of greenhouse gases, construction of a computer model of the greenhouse effect with such variables as clouds, cities and plants and testing the model by using data from the past to predict present conditions.
