Catalyst: Can you solve the 'travelling salesman problem'?

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 ...

Catchment management: the drain is just for rain

Stormwater originated as rain and flows into creeks, rivers and other water bodies. Any rubbish or chemical pollution collected during this journey can end up polluting the waterways. This activity looks the impacts of stormwater and rubbish in our waterways. Outcomes of this learning activity are for students to: understand ...

Energy skate park

This interactive simulation explores the conservation of energy in a skater moving on a curved ramp. In a series of simulations students explore the transformation of energy between kinetic and potential energy; how changing the mass, friction, or gravity affects the skater's energy; students can predict position or estimate ...

Waves Intro

This interactive simulation explores waves, using simulated water waves, sound and light. In a series of simulations students make waves with water, sound, and light and see how they are related; explain how changing the frequency and amplitude affects the characteristics of the wave and design an experiment to measure ...

Experimentals: Do different things fall faster?

Want to find out what happens when you drop a watermelon and an apple from the top of a building? In this clip, Bernie Hobbs and Ruben Meerman, investigate whether the mass of an object influences how fast it falls. Bernie and Ruben ride the 'Giant Drop' at Dreamworld, drop a watermelon and apple from an eighth floor balcony, ...

Atoms of Fire: Atoms and organic compounds

Can you imagine someone who lived over 2400 years ago saying that all matter is made up of atoms? Democritus, an ancient Greek, did. Explore the history of this scientific idea with chemist Amanda Tilbury. Hear how Swedish scientist Jöns Berzelius postulated much later that only living tissue could make an organic compound ...

Exploring atoms: atom structure

See how scientists such as Ernest Rutherford have investigated the structure of atoms. Explore possible models. Fire charged particles at atoms and find which model best fits the results. This learning object is one in a series of six objects. Three of the objects are also packaged as a combined learning object.

Catalyst: Climate and bushfires in Australia

What can science tell us about the major cause of bushfires in Australia's past? How can it help us predict future bushfires? Two scientists discuss evidence related to bushfire regimes (bushfire patterns, types and intensity). Please note that this clip contains recent images of homes destroyed by fire that may disturb ...
