Life cycle analysis has been more recently referred to as Life Cycle Assessment, which is an internationally recognised method of studying the potential and environmental impact of a product throughout its life “from the cradle to the grave”. The impact of a wide range of materials is covered in the program, including the acquisition of raw materials, production, transportation, use and disposal of metal, plastic and wood products. The program features interviews with Tim Grant, the project manager for life cycle assessment at the Centre for Design at RMIT University, who shares his experience in applying LCA and other environmental tools with various organisations and companies.

Lifting the Lid: How Computers Work
Most computer users are familiar with terms such as chips, hard drives, RAM, but what is a chip and what does it actually do? What does a hard drive look like and how does it work? Although the details of what lies under our computer cases is changing rapidly, the underlying design remains relatively stable. Aided by illustrative graphics, this program looks at the functions of the main components of a PC. It also covers a brief history of the development of the PC’s main, or mother board over the past 15 years.

Foods for Special Needs
Agriculture and trade have completely revolutionised our diets. We now have an amazing range of things to eat. But not everyone can feast freely. Many people have special needs that shape what they can eat and when. Food for Special Needs examines food allergies and intolerances, dietary-related diseases and disorders. Cultural and religious beliefs that determine diet are also considered.

Behind the Scenes
This program focuses on the preparation of meals and their presentation, we first look at the range of knives used by chefs. Presentation and garnishes come next, including julienne vegetables, deep fried vegetable crisps, turned mushrooms, radish roses, fanned strawberries, segmented oranges and carrot curls. This program also demonstrates plating a meal, featuring an entree, two types of main course, and a dessert.

Setting the Scene
In this program we look at different aspects of planning a menu: food combinations, special dietary needs and budgeting. We explain table setting, including the components, types of covers and folding serviettes and we’ll examine styles of service, and various aspects of serving the meal.

Water: A Unique Chemical
Water is a unique chemical. Without it, life as we know it cannot exist. It exists in all three phases naturally on Earth. At first glance, the chemistry of water appears a very simple, but it has some remarkable and unique properties, because of its molecular structure and composition. This excellent production examines some of water’s important chemical properties, including its polarity and the strength of bonds between water molecules, dispersion forces, heat capacity and its ability to self-ionize. Sections are titled: water, a unique chemical; the three states of being; the nearly universal solvent; and water and chemical reactions. It is an ideal learning resource for senior secondary level students of Chemistry, with high quality imagery used to explain complex principles.

Chemical Analysis Techniques
Chemical analysis has wide-ranging applications, from its use in many different industries such as mining, environmental management and chemical manufacturing, to forensic science and cutting-edge medical testing and procedures. This high quality production explores a range of important chemical analysis techniques, including chromatography, mass spectrometry, infra-red and nuclear magnetic resonance (NMR). It explains how chemical principles are applied in the various analysis techniques and how it is possible to identify very specific chemical elements and compounds using them. Students of Chemistry will find the structure of this outstanding resource, together with the graphics and other visual imagery, engaging and effective in explaining the range of concepts covered.

The Energy of Chemical Reactions
Chemical changes occur around us, and inside us, all the time. When chemical reactions happen, one or more new substances are formed and energy is either given off or absorbed in the process. Spontaneous chemical reactions, those that occur naturally under favorable conditions release free energy, meaning they are exergonic. Endergonic reactions, by contrast, require net energy input to make the reaction happen. This excellent learning resource explores energy associated with chemical reactions, and cover areas such as activation energy and product formation, standard heats of reaction, thermochemical equations and Hess’ Law, and specific heat capacity and calorimetry. It is essential viewing for any Chemistry student, providing clear explanations and easily understood visuals, including comprehensive chemical equations, about concepts that many students find challenging.
