This interactive simulation explores speed, acceleration and unbalanced forces in a simple system. In a series of simulations students identify when forces are balanced vs unbalanced; determine the net force on an object with more than one force acting on it; and predict the motion of an object with zero net force or given ...

Imagine you are a salesperson having to travel between multiple locations. How would you achieve this in the quickest way possible? This is a problem that has stumped mathematicians for decades, and there is even a prize for anyone who can come up with an algorithm to solve it. In this video, three methods are used to try ...

This study guide considers the science behind breeding, genetics, health and animal welfare in the cattle and sheep industries - keeping animals free of disease and parasites, improving biodiversity and protecting against feral animals. A range of articles and student activities explores how farmers and scientists are working ...

• TLF-IDM020088

This study guide examines ways Australian cattle and sheep farmers are monitoring and researching how greenhouse gas emissions are being produced by farms and steps farmers use to reduce them. This includes selective breeding programs to produce cattle and sheep whose digestive processes emit less methane, research into ...

This interactive simulation explores how genetic variability in a population leads to natural selection. In a series of simulations students explore which mutations are favoured by the selection agents of predators and food variety and which mutations are neutral; which traits change the survivability of an organism in ...

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy. This TedEd animation (4:58 ...

This is a black-and-white photograph of the exterior of an exhibition home made of fibrolite (fibro-cement) that was constructed by James Hardie and Co Ltd (now known as James Hardie Industries). The street outside the home is crowded with people, some of whom have come to view the fibrolite home. The photograph measures ...
