We'd like to think our dogs offer us comfort when we get upset or injured. Can the 'classic test' of empathy in humans tell us something about dogs? The reporter investigates the phenomenon of empathy: the ability to be aware and sensitive to the feelings of others from their perspective.
This Connected Learning Experience (CLE) students explore the digestive system in higher animals. In this investigation, the specialised structures and functions of cells in the tongue are explored to determine how this organ helps animals survive.
Claims regarding the taste map of the tongue, published in 1901, are evaluated ...
This Connected Learning Experience (CLE) explores the digestive system in higher animals. Students will learn about the role of the digestion in the context of modelling the human digestive system.
Lesson focuses on how engineers design tyre treads to increase safety and reliability. Students are presented with the challenge of designing a new tyre tread that will be safe when driving in rainy conditions. Student teams will design and construct a sample tread out of clay, then test and evaluate the effectiveness of ...
When you walk with a glass or a cup filled with liquid, do you find yourself spilling some of the liquid? Some scientists have studied why this happens and how best to avoid it.
Do you think left-handed people have characteristics that are different from right-handed people? It seems that right-pawed dogs have certain characteristics that make them better Guide Dogs, but how do you find out whether your dog is right-pawed or left-pawed to begin with? Watch this experiment to find out!
Fiery red, cool blue and sunny yellow are phrases used to describe feelings associated with colours. But what actually is colour? Why is it there and what helps us to see it? Follow Chloe Sheridan as she unravels the complexity of seeing colour by delving into its physics and biology. She entered this video in the 2013 ...
Have you ever wondered what causes that annoying 'red-eye' in photos taken with a flash? How can you avoid or lessen it? Marko Moutafis uses eye models as he takes us through a lively demonstration to help answer these questions. He entered this video into the 2013 Sleek Geeks Eureka Science School Prize competition.
This 5 minute video segment from Catalyst describes how a school student conducted his own scientific investigation. Daniel O'Doherty was intrigued to find out what was the carbon impact of travel to and from school each day, and what could be done to reduce this impact. His project won the 2008 Action Against Climate Change ...
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?
In this lesson, you will learn about how particles behave when they are exposed to higher temperatures. Diana will conduct experiments to show you how a gas, liquid and solid behave differently when they are heated.
If you picked up a paper book and a metal box do you think one would feel colder to the touch or would they feel the same? Watch this clip to see if people's predictions about the temperature of objects match their observations. You may be as surprised as they are!
Discover what scientists are doing to try to save the striking-looking Southern Corroboree Frog from extinction. Watch this clip to learn about this critically endangered Australian frog, including why it is threatened and how a frog-proof fence might help its survival.
Have you ever wondered what happens to the on-farm waste from our food crops? It's not all left to rot into the soil. Watch as an innovative farmer joins forces with a clever engineer to turn farm waste into a new product with unique properties.
An expert in plant pollen finds herself working in forensic science, helping police solve crimes. Find out how Dr Lynne Milne's knowledge of plant pollen was used in a criminal investigation. See how soils have a 'signature profile' based on the types and abundance of pollen.
Did you know that samples of polar ice can tell us what the atmosphere was like almost a million years ago? The Bureau of Meteorology has records that go back 3000 years! Why do you think scientists are interested in learning what the atmosphere was like before industrialisation?
Dr Paul Fraser has been part of the Greenhouse Gas team at the CSIRO for over 40 years. His team measures the carbon dioxide in the atmosphere, by taking and analysing air samples from different locations around the world. Paul explains that there are a number of versions of carbon dioxide, made up of different isomers ...
