• TLF-IDM019538

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-IDM008891

This is a colour video clip of marine scientist Abby Smith discussing the effects of increased levels of carbon dioxide on marine animals. Smith is a teacher and researcher at the University of Otago, New Zealand.

• TLF-IDM008890

This is a colour video clip of marine scientist Abby Smith discussing the process of ocean acidification and the effects on marine animals. Smith is a teacher and researcher at the University of Otago, New Zealand. The clip also shows some marine animals, and some activities that have led to ocean acidification including ...

• TLF-IDM008883

This is a colour video clip of marine scientist Associate Professor Abby Smith discussing the role bryozoans play in marine ecosystems. The clip shows Abby Smith, a teacher and researcher at the University of Otago, New Zealand, being interviewed. The clip also shows underwater photos of bryozoans, fish and corals.

• TLF-IDM016673

This is a lesson plan, complete with instructions, materials list, worksheets and photographs of the expected results from the ABC's surfing scientist. The students are encouraged to participate in a first-hand science activity using sugar and colour-coated chocolate lollies.

• TLF-IDM015723

Have you ever heard of a catalyst? Watch as the Surfing Scientist, Ruben Meerman, demonstrates the power of a catalyst. He adds one to just two other ingredients to create a chemical reaction with spectacular foaming results - just like elephant toothpaste!

• TLF-IDM015489

Have you ever accidentally sprinkled sugar on your dinner or spooned salt into your coffee? Those white crystals might look the same but they taste very different because they are made of different kinds of atoms bonded in different ways. Discover how chemists identify what kinds of atoms a compound is made of, then find ...

• TLF-IDA006027

In this activity, students design an insulation system for keeping ice cold. They investigate factors that effect how quickly an ice block melts when in sunshine, then design and test insulating mechanisms using different materials and structures. They consider the different ways heat energy is transferred (conduction, ...

• TLF-IDM019504

This interactive simulation explores how genetic variability in a population leads to natural selection. In a series of simulations students explore which mutations are favoured by the selection agents of predators and food variety and which mutations are neutral; which traits change the survivability of an organism in ...
