It’s Alive: Conditions on Earth

In this resource, students investigate and measure the conditions of planet Earth. They explore temperature, gravity and the needs of living things. Students also discuss how some conditions on Earth are constant, while other conditions regularly change, and how living things have adaptations to survive these changes.


Digging palaeontology

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.


Some plants don't need much fertiliser

Native to western New South Wales, silver senna (or Senna artemisioides) can also be found in other parts of Australia. Like most native Australian plants, silver senna likes dry, warm climates and dislikes frost, especially when young. It fixes its own nitrogen and so doesn't require additional fertiliser. See if you can ...


Red kangaroos: efficient hoppers

The red kangaroo can cover many kilometres at speeds of around 30-40 kilometres per hour. Watch these amazing animal athletes in action and find out what makes them such champion long-jumpers.


Silk of spectacular spiders

Discover what makes spiders so spectacular in this award-winning clip about the feeding habits, adaptations, and physical features of spiders. See close-up footage of spiders weaving their webs, catching their prey, and sheltering in their retreats. Brandon Gifford entered this video in the 2013 Sleek Geeks Eureka Science ...


Cambrian fossils on Kangaroo Island

All fossils provide interesting clues to what life on Earth was once like, but there is something quite unique about the fossils found at Emu Bay on Kangaroo Island, South Australia. Watch this clip to find out why.


Ancient fish out of water

See fossil evidence of the largest Devonian lobe-finned fish ever found. Known as the Age of the Fishes, the Devonian period marks an important time in the evolution of land animals. Find out why this fossil is an important find.


How do mangrove trees survive?

Imagine a plant that lives in mud and is soaked in sea water twice a day. Find out how mangroves thrive in conditions that would kill other plants. View the amazing adaptations that make mangroves such special plants.


Minmi, Australia's ankylosaur dinosaur

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.


Captain Ahab learns about whales

Have you ever wondered how long whales have been swimming around in our oceans, and where they came from? Watch this short skit in which knowledgeable shipmate Ishmael (otherwise known as young scientist Cassandra) explains the evolutionary history of whales to Captain Ahab.


Time to act on climate change

Could human activities push the Earth's climate to breaking point? Find out why concentrations of atmospheric carbon dioxide are reaching critical levels and how we can lessen future climate change. View some of the evidence and claims presented in this clip.


Antarctic wildlife

What wildlife would you expect to see in and around Antarctica? Come aboard the Australian ice breaker Aurora Australis to find out. How have these animals adapted to the harsh environment?


Little penguin adapting big time!

Discover the features, habitat and adaptations of the little penguin, and the conservation efforts aimed at helping it to survive in the wild. Also known as the fairy penguin, this species is not endangered but in Australia is only found in small isolated populations.


It's all in the trunk

Elephants are large, but how large? See how heavy a bull elephant is when its mass is described in numbers of cars or people. An elephant's trunk is a wonderful adaptation - a perfect tool. See why! Find out how elephants communicate using everything from loud trumpeting to low-frequency rumbles.


Elephant evolution

The elephant, the largest land mammal, is believed to have evolved from an aquatic pig-like animal. Many of its ancestors, such as the woolly mammoth, have become extinct, but three species of elephants remain. Find out to which marine animals elephants are thought to be closely related.


Antibiotic resistance

Antibiotics are drugs used to treat infections and diseases caused by bacteria. Unfortunately, bacteria has an enormous capacity to adapt, which means they become immune to antibiotics. What are the repercussions of bacteria in our bodies becoming resistant to antibiotics and why could this present a big problem to human health?


Sending seeds into space

Why might we need to keep a collection of seeds from all over the world? Where would we keep a collection like that? Should we send some of them into space? Watch this clip to reveal answers to all these questions and more.


Decreasing snowfalls threaten pygmy-possum

The Mountain Pygmy-possum spends winter hibernating beneath snow at temperatures of two degrees. But what could happen to the species if there is little or no snow blanket to hibernate beneath? Watch this clip to find out.


Matilda, a giant diamantinasaurus dinosaur

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.


Leaping tall felines in a single bound

Discover one of the greatest high-jumpers of the animal world. If cat-fleas were the size of humans, they could jump 400 metres into the air! Find out how and why these tiny jumpers leap so high.
