Sedimentary, igneous and metamorphic rocks contain minerals and are formed by processes that occur within Earth over a variety of timescales (ACSSU153)
Imagine the forces required to change one type of rock into another type. Listen to presenter, Bernie Hobbs, explain the forces that transform sedimentary rocks to metamorphic rocks. She visits the Australian Nuclear Science and Technology Organisation (ANSTO) to demonstrate how limestone can be transformed into its matching ...
Dr Ben Kear, a paleontologist at La Trobe University, introduces muttaburrasaurus, a dinosaur found near Muttaburra in Queensland. Muttburrasaurus was a giant herbivore, a plant eater. What does its fossilised skull really look like?
Have you ever wondered how scientists know when the early mammals appeared on Earth, or how long ago dinosaurs died out? Watch this clip to discover the role of fossils, and the rocks they are found in, in revealing the order and history of life on Earth. This clip takes you to fossil sites in Queensland; and to Shark Bay ...
Dr Ben Kear, a paleontologist at La Trobe University, introduces Minmi, one of Australia's most famous dinosaurs. It's an armoured dinosaur, a small ankylosaurus coverered in nodules of bone and bony spikes. Meet the man that discovered Minmi.
Travel back in time, deep into Australia's past, and find out what plant fossils from the Eocene epoch reveal about previous climate changes. Eocene plant fossils, found in rock in Tasmania, provide evidence about the landscape, vegetation and climate 50 million years ago. How might this information be useful for our future?
Why did most of the world's oil deposits form at a specific prehistoric time? Learn how overheated super-greenhouse climates caused vast stretches of the world's oceans to stagnate and become depleted of oxygen. Discover the connection between these anoxic events and Earth's oil reserves. Watch scientists investigating ...
Imagine the power of wind and water as mountains are worn down and sent to the sea. Recognise the importance of water as it moves particles of different sizes and deposits them to form new soils that support plant and animal life. Consider evidence that erosion is an important process in the formation of new rock in a continual ...
Uluru is found in Uluru-Kata Tjuta National Park in Australia's Red Centre. This region contains many landform features and is a place of special significance for both Aboriginal and non-Aboriginal peoples alike. Find out about the Earth movements that created these incredible landforms and the creation stories of the area's ...
This online resource is a Connected Learning Experience (CLE) explore the rock cycle.In this investigation, students explore the processes in the rock cycle that result in new rocks being formed.
Through hands-on investigation, they learn about the formation and properties of the different types of rocks.
Explore the different types of minerals inside rocks. See that most rock-forming minerals are made up of just two common elements. Discover that most minerals are made up of the same basic building blocks put together in different ways, and that this can explain some of their properties.
Palaeontologists piece together what ancient life looked like by observing fossilised remains, like an insect from 20 million years ago, dino droppings, tracks and egg shells.
Explore how forces and energy are continually shaping and changing the Earth's surface. Find out about fast and slow changes and the connection between them first observed by English scientist Charles Lyell. Discover the Earth's age, how rocks form, what they contain, and what they reveal about the Earth's long history.
When did Diprotodon die out? To answer this question, teams of scientists and volunteers are working together to excavate Diprotodon bones and study the landscape where they're found. Go on the road with Catalyst to the 'badlands' of South Australia and investigate the evidence behind Diprotodon extinction.
Imagine tunnelling deep, deep below the Earth's surface. What do you think you would find thousands of kilometres down? Watch this clip to find out what is inside the Earth, what it's made up of and how hot it is. Find out about earthquakes, volcanoes, and geysers, and how they help us to understand about the composition ...
Matila is a giant sauropod, a diamantinasaurus around 95-98 million years old. It's one of the amazing dinosaurs discovered near Winton. Sauropods were giant herbivores (plant-eaters). Other kinds of sauropod include Brachiosaurus, Diplodocus, Apatosaurus and the massive Argentinosaurus.
Do all scientists wear white lab coats and work with chemicals? Watch this clip and discover how a career in science can take you soaring to dizzying heights. Find out what an exploration geologist does and why helicopters are used in the job. This clip will inspire you to consider a career in one of the many varied fields ...
See how crude oil became indispensable to modern life as the transport industry developed and our 'thirst' for oil developed. Find out how petrochemicals derived from oil are contained in virtually everything, from plastics and paints, to pesticides and painkillers.
Follow a carbon atom as the central character in a story about crude oil. Watch as this ancient chemical that has existed since the dawn of time is recycled through all life forms, oceans, rocks and the atmosphere. See the origins of the vast oil fields on which the modern world now depends.
How long does it take to wear away a mountain? Discover the forces of nature that can turn rock into soil and a mountain into a small hill. Watch as the presenter demonstrates some of those forces that can change the face of the Earth. Find out that even plants and animals play a role in creating soil.
Imagine what the world looked like hundreds of millions of years ago. Watch this clip to discover how fossils are preserved and what they tell us about the Earth's past. Find out about trilobites, an intriguing, ancient creature that lived in the sea during the Cambrian period. Their fossils are a piece of the past helping ...
