This is an information sheet providing an introduction to different varieties of rocks and minerals that might be mistaken for fossils. It is also available as a two-page pdf file for download.
The world's largest dam project is set to bring enormous benefits to the Chinese economy. But there's a potential side-effect of altering the natural system - the likelihood that more geological disasters such as landslides will occur in the area. Find out why in this clip from 2008.
This is a black-and-white photograph, taken on acetate film, of a natural rock arch formation at Sorrento Back Beach on the Bass Strait side of the Mornington Peninsula, Victoria. The photograph has been taken at low tide, looking through the arch of weathered rock towards the ocean. Some sparse vegetation is growing on ...
See how geology can tell us a story about how Earth has changed over time, as well as help predict natural disasters and save lives. Find out how geology can help you understand the world around you even when you are at the beach.
China has built the massive Three Gorges Dam to provide hydro-electricity. The dam provides power without the harmful emissions produced by burning coal. But are there other costs? Hear from a Chinese professor whose opposition to the dam has waned, but who calls for careful attention to the problems that this dam has created ...
See the world's largest dam - China's Three Gorges Dam - which provides hydroelectric power. Learn about some of its benefits, and, as you watch this clip from 2008, consider these benefits against the social cost of displacing local communities.
Farmers along Victoria's Upper Murray claim that soil erosion on their properties is being caused by water released from the Snowy Mountains Scheme, a hydro-electricity project located in the Southern Alps. This clip from 2013 investigates the degradation occurring in an area where prime agricultural land is valued at 10,000 ...
Come on a journey with young scientist Alex Jaeger as he tells us about fossils found along the Jurassic Coast in Victoria. Find out how the area's landscape and ecosystem have changed over time. Alex explains how fossils are formed and what they reveal about Australia's past in his 2013 Sleek Geeks Eureka Science Schools ...
In English coastal villages, erosion by wind and waves has washed away great swathes of land. What drives this process? Can anything be done to protect people's homes against the merciless power of the elements?
Take a trip around the English coastline. In each location, the erosive power of the wind and the waves is obvious. But it's differences in the underlying geology that account for the diverse range of landforms that you are about to see.
Coastal settlements are often battered by forces of erosion. See how planners use accurate, reliable data about the changing coastline to combat erosion. Take a trip to the beach to see how technology, including GPS and airborne laser systems (Lidar), are lending a hand.
Join canyoning instructor Zak Griffiths as he investigates a river's incredible force and energy. See how features of the river can change from one day to the next. View an animation showing how various materials in the river are transported by moving water.
Moving water can be a powerful force of nature. The speed of the water flow directly affects particle movement (transportation and deposition). See how the Hjulstrom Curve graph helps understand erosion by plotting the relationship between particle size and river velocity.
Is soil our most important natural resource? Erosive scars in many parts of Australia's agricultural landscape suggest we should be doing more to protect this asset. Meet Peter Andrews, a soil advocate. Peter's approach to landscape management might be unconventional, but it appears to be gaining support.
This comprehensive teacher resource focuses on the observable properties of the sky and landscape in their local environment. They observe changes of different scales and time scales and classify changes as natural, constructed or managed. Students investigate the impact of people, compare features of objects before and ...
Look at how a tree makes a shadow during a sunny day. Notice that objects always casts shadows that face away from the Sun. Examine how the shape and position of a shadow is related to the time of day and position of the Sun. Explore the shadows cast by different objects such as a bike, an umbrella and a child. Position ...
Look at how a tree makes a shadow during a sunny day. Notice that objects always casts shadows that face away from the Sun. Examine how the shape and position of a shadow is related to the time of day and position of the Sun. Match the shadows cast by different objects such as a bike, an umbrella and a child.

Listen to a weather report on a radio. Dress a character in clothing suited to the weather conditions predicted. Sail in a yacht race.
Position jigsaw pieces to complete a diagram of sediment layers. Explore the formation of rocks such as marble, mudstone, shale and granite. Look at the effects of erosion on rock layers. This learning object is one in a series of three objects.
