• TLF-IDL2357

Select energy sources and energy converters to build energy chains to power appliances and vehicles. Examine how each energy converter in a chain loses some energy and reduces the energy available for use. For example, show that using a solar panel and an electric motor to drive a car delivers only 16% of the original energy ...

• TLF-IDM019063

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-IDL2355

Build energy chains that make electricity. Select different energy sources and choose energy-converters to match. Arrange converters into the correct chain so that the energy can be delivered as electricity. Examine the waste products and side effects that occur with each converter. For example, find out the environmental ...

• TLF-IDM019560

This is an interactive resource about the potential and kinetic energy changes as a skater rolls around a skate park. Students learn about conservation of energy with a skater, they can build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. Students can also ...

• TLF-IDL9128

Heat ice and record the temperature and states of water at specified times. Plot a graph of temperature against time and relate sections of the graph to the states of water. Observe animations of water particles over time and explain the shape of the graph in terms of particle theory. This learning object is the first in ...

• TLF-IDL1130

Watch an animation of the Earth rotating in space showing day and night, the equinox where locations on Earth experience close to equal hours of daytime and night-time (12 hours) and views of the Earth from above the North and South Poles. Position a camera at different places on the Earth's surface to take a time-lapse ...

• TLF-IDL47

Answer questions about how nuclear reactors work. Operate controls for a simulated nuclear reactor. Adjust the fuel type, position of control rods, coolant type and flow speed. Generate electricity without causing a meltdown. This learning object is one in a series of two learning objects.

• TLF-IDM020975

This resource guides students through an extended school-based or local investigation focussed on energy use and efficiency using the five-step sustainability action process. The resource supports the investigation of a real-world issue or problem. Students develop and implement a chosen sustainability action and then evaluate ...

• TLF-IDM013655

This interactive resource takes students on a journey of discovery in the energy and mining world. Oresome world contains five games or modules: Coal, Energy, Gas, Low emissions and Mining, and within each of these there are several facilities to explore, such as the Underground mining site, Hydroelectric power station, ...

• TLF-IDM016514

This 11 minute video segment from Catalyst explains how the sun can impact on Earth's power grid and satellite communications. This program also describes recent technology to study the sun and understand the causes of coronal mass ejections.
