Nutrition Australia

What should we eat to keep fit and healthy? Nutrition Australia provides a valuable web site with a vast array of up-to-date information on food and nutrition.

You can download food facts sheets, written by the many Australian nutrition professionals who regularly contribute.

Here you can find answers to frequently asked questions (FAQs) about the latest medical research on cholesterol and heart health, the benefits of high-fibre food, and weight loss and exercise. Other questions discussed include: Is sugar harmful? Does drinking red wine lower the risk of heart disease? Can arthritis sufferers gain relief by avoiding "acid" foods?

This site also tells you how to eat well on a budget and how you can have a nutritionally-sound barbecue.

Nutrition Australia dietitian, Rachael Bradford, offers a number of tasty ideas on how to provide your children with nutritious food for their lunch boxes.

Australian War Memorial
www.awm.gov.au

The Australian War Memorial is one of the country's great institutions and has been described as the spiritual heart of the nation.

Its excellently organized web site caters for everyone from the casual web-surfer to the serious history buff.

You can take a virtual tour of the memorial's galleries and grounds, or view famous battlefields where Australian troops saw action, such as Gallipoli Peninsula, Anzac Cove, Villers-Bretonneaux or Menin Gate, Ypres.

You can discover Australia's military history and locate historical documents. You can get information on current attractions, such as the memorial's travelling exhibition, Forging the Nation: Federation - the first 20 years, which explores Australia's spirit and identity "from Bushman to Digger".

Most exciting of all is the web site's vast collection of photographs, sound recordings, art, film, official records and private records, all linked to a record search of the National Archives of Australia's biographical archives. With all of these resources at your fingertips, you can look up (and find within a very few minutes) useful data, be it for your family history or just curiosity.

This web site is information technology at its very best - exciting, comprehensive, and genuinely user-friendly.

The Investigator Science and Technology Centre
www.investigator.org.au

Don't forget some of SA's own attractions. The Investigator Science and Technology Centre at Wayville hosts a variety of fun-filled, interactive, "hands-on" activities for all ages.

Currently showing at Wayville, until July 22, is Special FX II: The Secrets Behind the Screen, a follow-up to the most popular exhibition the Investigator has ever hosted. SFII lets you in on all the technological wizardry of the most popular movies of all time.

More than that, visitors can actually experience movie special effects first-hand. After passing through the exhibition's magnificent archway entrance, visitors cross a wooden bridge suspended by rope in a blue set. On a large television screen they are able to see themselves seemingly suspended precariously over hot bubbling lava in the mouth of a volcano. This is achieved by superimposing the visitor and the bridge onto a scaled model of the lava-spewing volcano using blue screen technology.

A similar technique is used for an interactive display of the sinking of the RMS Titanic, in which visitors can see realistic images of themselves falling from the sinking ship.

Visitors can perform karaoke and see themselves on screen with some spectacular background effects and images. They can examine other movie special effects, such as cartoon animation; a computer which can "morph" faces into those of Marilyn Monroe or Frankenstein's monster; various tricks of lighting which are used for creating a strong sense of mood on film studio sets; some spectacular examples of time-lapse photography; and a "virtual" roller-coaster ride.

The Investigator is an exciting SA showcase of tomorrow's world for all the family, and fully lives up to its aim of promoting awareness, understanding and appreciation of the role of science and technology in the world.
