Circuits - upper primary

This collection of 11 digital curriculum resources is organised in three categories - types of circuits; circuit applications; and conductors and insulators. Interactive learning objects enable students to build and manipulate simple series and parallel electric circuits. Students investigate how current flows, effects ...

Syllabus bites: Electricity

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.

Tidal power

Journey to Bathurst Island where strong tidal currents can be found in the Apsley Strait. Observe how the Nguiu community is investigating the use of tidal power to provide their electricity needs instead of using non-renewable and expensive fossil fuels.

Solar power

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.

Coal seam gas production

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, ...

Supercapacitors: new battery technology

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 ...

Wind farming: benefits and drawbacks

Discover why some people are opposed to wind farms even though they generate electricity without burning any fossil fuels. Travel to Australia's biggest wind farm to find out how wind turbines work, some of their benefits and drawbacks, and what locals think of them. Consider all views and make up your own mind about whether ...

Underground coal gasification

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 ...

Measuring Voltage

In this simulation students select to measure the voltage across one, two or three light bulbs in series to measure the voltage drop across one, two of three bulbs.

MovingImage

Measuring Current

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.

Capturing the power of the sea

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.

Clean alternatives to fossil fuels

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 ...

Burning coal on a grand scale

Scotland's Longannet power station can burn up to 1000 tonnes of coal an hour! One of the largest coal-fired power stations in Europe, it produces much of Scotland's electricity. It also produces huge volumes of greenhouse gases. Take a tour through this huge facility as it was in 2012, and find out about a gas emissions ...

Australian businesses generating renewable energy

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 ...

Let the electricity flow

Electricity flows easily through some materials, known as electrical conductors, and not through other materials, called insulators. Watch this clip about early English scientist Stephen Gray and his groundbreaking experiments investigating the flow of electricity. Which materials allow the flow of electricity and which ...

Energy that connects us to a world of fossils

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.

A car for the future

Hydrogen fuel cell cars run on electricity created by a reaction between hydrogen and oxygen that occurs in a fuel cell (battery) contained in the vehicle. How might this new technology be a way of reducing carbon dioxide emissions? Find out here, but also see why there are some challenges to getting this technology onto ...

Millions of years to form, minutes to burn

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.
