In this resource students explore how an electromagnet works in real life. They can then apply their learning in an electromagnetism game by changing the magnetism of a scrap lifter in a scrap yard and removing various amounts of scrap. The resource demonstrates the connection between the power applied, the number of coils ...

This is an interactive teaching and learning resource that years 7 to 10 secondary students can use to simulate the orbits of the Earth, Moon and a space station while altering the physical quantities involved. Orbital pathways, velocity and force vectors can be displayed in either scale or cartoon views. The mass and velocity ...

Many scientists believe we are already experiencing megafires and that they will continue to increase in the future. In this clip you will hear from Australian scientists at the forefront of fire research. Discover what they have to say about the causes, projections, and consequences of an increased megafire threat.

The phases of the Moon and lunar eclipses occur due to the Moon's orbit of Earth, and its position in relation to both the Earth and the Sun. Watch this animation showing a model of the Moon's orbit, its phases and a lunar eclipse. Discover what a total lunar eclipse is and what causes the red colour of a 'blood moon'.

Figuring out how to clean up contaminated rivers is a big challenge. It's also tricky to work out where the most contaminated parts of a river system are and whether its fish are safe to eat. Watch this video and learn how engineering has helped to solve these problems. Why do you think engineers looked to the bottom of ...

Demand for certain kinds of food changes with time as people's tastes change. Avocados were not always popular, but in recent years their popularity has increased so much that supply cannot keep up with demand. Learn how stem cell scientists at the University of Queensland are leading the way in research that could cut ...

The latest coal rush is sweeping across Queensland, but this time without having to dig the coal up. Animations show the processes used to extract coal seam gas (CSG) out of the ground, which can then fuel gas turbines in power stations. Discover how CSG avoids some of the environmental effects of traditional coal mining, ...

How did the ancient Egyptians move and lift huge stones during construction of the pyramids? Secondary student Angus Atkinson designed an experiment to find out how the lives of pyramid workers could have been made easier. See how as you watch this video, which he entered in the 2013 Sleek Geeks Eureka Science Schools Prize.
