This interactive simulation explores atomic structure, elements and the periodic table. In a series of simulations students use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge; predict how addition or subtraction of a proton, neutron, or ...

• TLF-IDA005851

This interactive simulation explores isotopes and nuclear decay. In a series of simulations students explore how the changing the number of neutrons or protons affects the atomic number and isotope; investigate and predict how the shell model depiction of an isotope based on the isotope symbol or name; and predict the resulting ...

• TLF-IDM020088

This study guide examines ways Australian cattle and sheep farmers are monitoring and researching how greenhouse gas emissions are being produced by farms and steps farmers use to reduce them. This includes selective breeding programs to produce cattle and sheep whose digestive processes emit less methane, research into ...

• TLF-IDM016174

This program deals with a range of human impacts on the Great Barrier Reef. Herbicides from land runoff have been traced to algae and sea grasses in river mouths and coastal zones along the Great Barrier Reef. Effects include retardation of photosynthesis and growth of corals. Other pressures on the reef include high water ...

• TLF-IDM016475

This resource contains lessons plans containing instructions and teachers' notes for an activity based on a chemical reaction that occurs when a soluble aspirin tablet dissolves and the fact that oil and water do not mix are used to create a model of a lava lamp. Students have fun while they learn about density of fluids. ...

• TLF-IDM016406

This nine and a half minute video segment from Catalyst describes how researchers from Monash University have hard evidence that cloud seeding can produce good amounts of extra rainfall. Data collected over a long period of time has give hope to scientists and environmentalists who are trying to reduce the impacts of droughts ...

• TLF-IDM016539

This 11 minute video segment from Catalyst provides an excellent explanation of the processes involved in recycling sewage for an urban water supply. It also provides a range of opinions and concerns in an excellent debate on the topic.

• TLF-IDM016547

This brief ABC News in Science article from 2009 gives an excellent example of responses of plants to temperature change and current Australian science. Plants use a genetic memory to recognise when it is spring and can even count the number of cold days.

• TLF-IDM016140

This 12 minute video segment from Catalyst demonstrates how scientific knowledge can improve the well-being of our domestic pets and change public opinion. This show exemplifies the benefits of the application of our understanding of genetics and evolution.

• TLF-IDM016525

This is a ten question multiple choice quiz on student understanding of issues specific to the Murray-Darling Basin, but are examples of common Australian environmental problems resulting from human activities. This is a non-threatening activity that provides excellent explanations as feedback.
