Apply different tectonic forces to plate boundaries. Compare the effects when plates collide, separate, or slide past each other. Investigate the causes of earthquakes, tsunamis and volcanoes. Investigate important boundary sites, for example the Mid-Atlantic Ridge, the Andes, the San Andreas Fault, the Himalayas, and the ...

Imagine tunnelling deep, deep below the Earth's surface. What do you think you would find thousands of kilometres down? Watch this clip to find out what is inside the Earth, what it's made up of and how hot it is. Find out about earthquakes, volcanoes, and geysers, and how they help us to understand about the composition ...

This is a student digital resource that contains interactive materials exploring many aspects of energy including the different forms of energy, the energy of moving things, heat, electricity, energy in food, and sources of energy used by modern societies. This resource contains a rich array of digital interactive activities, ...

• TLF-IDL5828

Investigate tectonic plate behaviour. Identify how plate movements produce many features of the Earth’s surface. This learning object is part of a series of three objects. The series is also packaged as a combined learning object.

• TLF-IDL10326

Test your understanding of the Earth's internal structure. Use animations and images to help you answer a series of questions dealing with the seismic exploration of the Earth’s internal structure and the structure of tectonic plates. View and print a report on your work. This assessment object is one in a series of two objects.

• TLF-IDM020101

This is a student guide that takes an in-depth look at chemical reactions with individual chapters on the structure of atoms, chemical changes and formula, radioactivity and nuclear energy, energy changes, and reactions involving acids and bases. Each part or chapter of this resource contains information, images and diagrams, ...

• TLF-IDM014092

This is a unit designed to help students understand the theory of plate tectonics and how this theory was developed from evidence scientists gathered and analysed. Students examine how tectonic events are monitored and how future events can be predicted. By simulating events that occur during an earthquake, they examine ...

• TLF-IDM020127

This is a teacher guide containing material to support the planning and implementing of lessons for a unit on chemical reactions. It covers topics such as atomic structure, elements and the Periodic Table, chemical reaction rates and energy, conservation of mass, radioactivity, combustion, and reactions involving acids ...

• TLF-IDM015944

Explore historical and modern efforts to battle human infectious diseases. Watch re-enactments of the experiments of Edward Jenner, who pioneered vaccination, and of Louis Pasteur's work showing how microbes cause infection. Peer down the microscope to see the microbial world that wreaks havoc on human health. Learn about ...
