Friday
17 October
10.30am
01. The Water Planet
This episode examines water's crucial role to life on Earth. Looks at the oceans in relation to temperature stability, the water cycle and the exchange of nutrients, oxygen and carbon dioxide between plants and animals. Even organisms on land carry an internal "ocean".

02. Amazing H2O
Describes the discovery of water's formula and how the polar nature of the water molecule gives it special properties. Capillary action, surface tension and water's solvent properties are demonstrated. Hot and cold water, as well as change of state are examined.
Friday
31 October
10.30am
03. Floating, Sinking and Swimming
Investigates how water's own weight is responsible for buoyancy and we examine the concept of pressure. A "cartesian diver" shows why there is no stable state between floating and sinking, except on a density layer. The program concludes with some simple physics of beaches.
Friday
7 November
10.30am
04. Taps and Toilets
A look at weather and the water cycle leads into the subject of water and civilisation. The question of where we obtain our water leads into a description of sources, especially ground water, on which so much of Australia relies. How is supply water treated? How is waste water treated? We finish with some major water issues, such as salinity.
