This resource is designed to support science teachers in addressing concepts in electricity in the BOS NSW Syllabus for the Australian Curriculum in Science - Stage 3. Making decisions about the use of electricity is approached from an understanding of circuits, sources and sustainability.

• TLF-IDM015387

Have you ever imagined how much energy the Sun outputs every day? Listen as Dr Charles Lineweaver, from the Planetary Science Institute at ANU, describes why a solar farm based in space can capture and use more of the Sun's enormous energy potential.

• TLF-IDM015531

Discover how nanotechnology is contributing to the creation of new, improved batteries that may soon be used in all our mobile phones and portable music devices - even in cars and trams. Catalyst's Tanya Ha looks at how traditional batteries produce electricity and how their efficiency may be increased by tiny devices known ...

How are scientists using technology to get energy out of coal without having to dig it up? Find out how underground coal gasification (UCG) burns and converts the coal to gas underground. Visit UCG trial sites in Queensland and hear how UCG avoids some of the environmental effects of traditional coal mining, but may have ...

• TLF-IDM016657

In this simulation students elect to measure the current in a circuit containing either one or two light bulbs in series and observe the relationship between current and brightness of the light bulbs. Students drag and drop a battery, switch, ammeter and light bulbs into position on a circuit.

Harnessing energy from ocean waves is a newer type of technology for generating electricity. But what equipment do you need to capture wave energy and how does it work? Venture inside a huge, submarine-like wave power machine on the Edinburgh coast to see how it converts wave motion to electrical energy.

Most of the world's energy comes from burning fossil fuels: coal, oil and natural gas. This results in huge amounts of greenhouse gas emissions. However, some countries are moving towards cleaner, renewable energy sources. Travel to Spain, Iceland and Scotland's Orkney Islands to learn about some alternative ways of harnessing ...

Imagine how much Australia could reduce its carbon emissions if every business generated its own electricity from renewable energy sources. It's now possible for large and small businesses to do just that. In this audio file, listen to how Elgo Estate wines reduced carbon emissions by installing a wind turbine, even generating ...

• TLF-IDM018780

Everyday energy sources like natural gas, oil, and coal originate in areas where buried plants and animals have been trapped under pressure for millions of years. We depend heavily on these 'fossil fuels', yet forget how closely they connect us to a world long gone.

• TLF-IDM019524

Venture underground into a coalmine and see how coal formed in layers from the remains of plants and animals that lived long ago. You'll soon see why it's considered a non-renewable resource, yet coal is a source of energy that generates about 40 per cent of the world's electricity.
