Giant Cuttlefish

This 12 minute video segment from Catalyst outlines the fascinating and unique features of the giant cuttlefish and its mass breeding at Point Lowly. Then it explains how scientists have determined the vulnerability of this species- the fact that the eggs are sensitive to high levels of salinity and the fact that they die ...

Expansion and Contraction

This is a problem-solving activity in which students are engaged in a challenge is to control virtual bridges using expansion and contraction so that a car can pass over them. In so doing they learn about the expansion of solids, liquids and gases when heated is applied. Students need to understand how a bimetallic strip works.

The Reaction of Metals with Acid

Students use this simulation to learn that react with hydrochloric acid to produce salt and hydrogen and find out how to test for hydrogen gas. The notice that sodium reacts violently and that magnesium reacts more quickly than zinc but that the hydrogen gas test is positive for both. Word equations are provided for all reactions.

Aerial Orang Utans

This 11 minute video segment form Catalyst shows that although the orang-utans of Borneo are threatened with extinction, we don't know exactly how many are left or where they are. The use of helicopters to locate their nests and estimate population size has helped to challenge our thinking about the requirements of this ...

Human-computer interface researcher

This brief video describes how Natalie is trying to create a seamless experience between the user and the computer or software. She uses her creative and technical talents to work out what the interface problems might be, come up with a solution, use a rigorous scientific process to prove if she is right or wrong, and then ...

Grand Daddy Fish

This six and a half minute video segment from Catalyst demonstrates how we draw inferences from observations of fossils. Fossil fish from the Devonian Period have produced some amazing discoveries. Last year a few of them were found with embryos inside and one even had a fossilised umbilical cord. This year they have found ...

Lens Simulation (sk- Intel)

Students learn about the application of light refraction by completing a series of tasks based on light refraction using both concave and convex lenses.

MovingImage

Drought culprit

This 12 minute video segment from Catalyst is an excellent resource for students researching how oceans influence conditions on Earth's surface. It demonstrates the advantages and disadvantages of using models in science and how our understanding is open to revision as more information comes to light.
