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.

Aggression
Are all people capable of murder? What drives people to violence? Can TV affect our actions and even influence us to acts of violence? This interview-led documentary style program examines aggressive media, aggressive behavior and the banality of evil with the support of original film footage of research and actual crimes. An excellent resource for studies in applied psychology, this program features research psychologists providing explanations and reasoning behind aggression.

External Factors Affecting Business: Natural Disasters
All businesses are exposed to some level of risk, but when a natural disaster strikes they can suddenly face a variety of unexpected and often extraordinary situations. What happens in a matter of seconds can sometimes take years to rebuild. The 2011 earthquakes in Christchurch, New Zealand and the 2009 bushfires in Victoria, Australia demonstrated how devastating natural disasters can be for small businesses. This investigative-style program explores the human cost for businesses affected by natural disasters, but also many of the logistical aspects, such as assessing property damage, dealing with insurers, monitoring finances, relaunching a business and creating disaster preparation plans.

Operations Processes
At the very heart of business operations is the production of products or services – the input of raw materials, human resources and capital, and the transformation process that turns input into output. Operations extend also to areas such as transport of raw materials, distribution of products or services, advertising and marketing, finance and management. This program examines operations using four different case study businesses in New Zealand and Australia, and also explores unpacking operations, inputs, the transformation process, outputs and operations, productivity and competitiveness.
