New Releases - Chemistry Concepts
This comprehensive learning resource consists of four video segments on key chemistry concepts with short answer and multiple choice questions related to each video, an interactive periodic table, and a PowerPoint demonstration. We explore atomic modeling through history, from the ancient Greeks and Chinese through to 19th and 20th century models. We examine the development of the periodic table, from the discovery and classification of different elements and their properties to Mendeleyev's system of classifying chemical elements. We also discuss various bonding models and the limitations they pose in accurately explaining and accounting for bonding phenomena.

In this program we look at covalent bonding. A short summary as to why bonding occurs is presented before viewers witness how electrons are shared in covalent compounds. We discuss how the geometry of molecules is predicted by the Valence Shell Electron Pair Repulsion (VSEPR) theory, the two types of weak forces of attraction between molecules, dipole interactions and dispersion forces, and covalent network solids which are formed from carbon atoms. Examples of network solids are addressed including diamond, graphite and fullerenes. With the assistance of animated graphics, this program provides viewers with a wonderful introduction to chemical bonding.

Before delving into metallic bonding, viewers are provided with an overview of why bonding occurs, learn about Gilbert Lewis's Octet rule and why the elements in the periodic table are categorised the way they are. We then discuss the importance of the 'sea' of electrons and how this explains the many properties of metal including their shine, and their ability to conduct electricity and heat, before being introduced to the different types of geometric arrangements including, body-centred cubic, face-centred cubic, and hexagonal close-packing. Join us as we bring metallic bonding to life in this visually rich resource.

The word 'chemicals' might bring to mind pools of swirling, poisonous mixtures, dangerous acids or secret formulas ¡K but they are far more prominent in everyday life than we might first think. Very little in the physical world around us occurs without chemical reactions being involved. In this way, many of the important processes in modern manufacturing and product use can be summarised with chemical equations. This program takes an in-depth look at five common products that are in use all around us and explores the chemistry behind their manufacture and/or use, including chemical equations. Using graphics and footage from inside manufacturing plants, we see examples of how chemistry is so prevalent in the real world - and examine various reactions taking place. The products are soap, polystyrene, aluminium, paint and car batteries.

In every classroom in every school, everyone has the right to a safe learning environment. Science laboratories present a whole range of potential hazards to people's health and well-being, and it is critical that both teachers and students are fully aware of their responsibilities to ensure the learning environment is kept safe at all times. Everyone's behaviour must be such that danger is minimized - both to themselves and others.
After a few years performing experiments in the school lab, it is easy to forget that science laboratories can be dangerous places. Unfortunately, accidents can and do occur. The most common ones are fire, chemical and thermal burns, cuts from broken glass, absorption of toxic chemicals through the skin, and inhalation of toxic fumes. Some of these accidents result in permanent injury. Awareness and preventative action are therefore paramount to maintaining a safe environment.
This program is aimed at students who are not new to science laboratories. It covers a range of safety areas, including general safety in science laboratories and specific areas of potential risk in chemistry, biology and physics labs. It is an ideal learning resource for students of this level to remind them of the ever-present need to act with safety foremost in mind at all times during science classes.

This program begins with an overview of the basic concepts of chemical equilibrium: reversible reactions, Le Chatelier's principle, the equilibrium law and calculating K. It also looks at how conditions in a reaction, other than temperature, can be changed and the consequences of a change in conditions. We examine how K changes when increasing and decreasing the temperature of exothermic reactions and endothermic reactions. Several problems are posed for viewer consideration. Finally, the industrial manufacture of sulphuric acid is explored and how the concepts of equilibrium apply.

Scientists have only been able to "see" and manipulate individual atoms in the last decade or so. How then were scientists able to probe the structure of an atom between 1870 and 1940 using simple apparatus? This program describes four key experiments which identified the fundamental particles, leading to the present nuclear model of the atom used by chemists. Some of the key experiments examined in the program include Cathode ray in discharge tubes, canal rays, mass spectrometer, Thompson's plum pudding model, Rutherford's gold foil experiment, the Bohr model and the orbitals and quantum mechanical model.

This animated story explores the concepts of chemical bonding. We set out the task of introducing these complex concepts through reflecting them in events that the characters experience, as some are robbed of electrons through others taking them. Who loses and who gains depends on their position in the periodic table. The program uses the plot of a crime thriller to bring to life topics such as ionisation energy and electronegativity at a simple level.

This program explores the history of atomic theory. Before Chemistry there was Alchemy. For thousands of years, people tried converting other elements and compounds into gold, and so the quest for gold began. Meanwhile, there were those in the quest for knowledge. The crazy atoms put on a pantomime, telling the history of Atomic Theory from their point of view! A fully animated program with lots of information about such people as: Leucippus, Empedocles, Aristotle, Epicurus, Gassendi, Boyle, Newton, Priestly, Lavoisier, and Dalton.

This fun program aims at reinforcing the basic concepts of chemical bonding. It is best used as a follow up to 'I came, I saw, I redoxed'. In this story the scientific concepts are presented as a parody of a James Bond movie: Gold Metallic Bond is sent off to investigate why Carbon, Nitrogen and other atoms are training themselves in other types of bonds. He discovers their 'bond' school and university, finding that they are all working towards Project D. Complex information is presented in a way that is designed to be fun at the same time.

We have contrived the story to fit in with the key redox reactions. It would be helpful to have a road map at hand ( the periodic table) so that when Atom Bond gets going, your students can keep up. However, this means the chemistry happens quite fast, so we have repeated the reactions in slow motion after the credits. The program explains reduction-oxidation, or redox, reactions via an animated story in which the mighty Caesium and his legion of Atoms set out to conquer the world. A number of reactions are covered and the properties of different types of atom explained.

This program is one of a two part series on the preparation and properties of polymers. Concentrating specifically on the addition process, it will be invaluable in demonstrating this complex subject. Students are introduced to the concept of addition polymerisation using polyethene from ethene. The program features many examples of the different types and properties of polymers, and includes: definition of terms such as monomer and polymer, simple molecular models to demonstrate how the double bonds in the monomers break to form the polymer, and demonstration of how the alignment of the monomer is important for the successful formation of the polymer.

This program looks at polymers formed by condensation reactions (as distinct from addition reactions). The idea that the properties of a polymer can only be understood examining the intermolecular bonding within the material is a key feature of the program. Using animation, patterns of bonding are illustrated in both thermoplastic and thermosetting polymers. The examples chosen include: natural polymers and synthetic polymers.

This program takes the bonding story one step further - the bonding between molecules and how this determines the state of matter. Two main types of interactions are explained - 'dipole-dipole' and 'dispersion forces' bonding - using illustrations from common chemical substances such as ammonia, sucrose and the hydrocarbons. The program concludes with a recap on how our knowledge of bonding helps us to understand and predict the behaviour of all materials.

This program explores further the idea that everything is made of particles. It looks at the difference between atoms and molecules, the difference between elements, compounds and mixtures, how an element like lead can exist in various forms (as an element or in compounds), and how this can affect its properties (e.g.. how poisonous it is), why a substance may dissolve in one liquid but not another. Features a visit to a scientific testing laboratory and discussions with a forensic scientist discussing arsenic and whether it may have contributed to the death of Phar Lap. A case study looks at a mysterious illness in a family pet, which is traced through scientific analysis to the presence of lead in the backyard soil.

This program provides a history of our understanding of the atom including the pioneering work of Dalton, Thomson, Rutherford and Bohr. It also features an animated love story of chlorine and sodium, showing how 'at the disco' atoms combine in various ways. We build up the first 18 atoms by adding protons, neutrons, and electrons. We see an animated love story of chlorine and sodium. At the disco, atoms combine in various ways.Carbon forms bucky tubes and balls, we see evolving molecular shapes C02, H20, NH3, CH4, some atoms dance in pairs e.g. N2. Chlorine is asked to dance with Ca, Al and C but waits for Na. They dance and transfer an electron. Love at last.

Describing the greenhouse effect in detail and following the "Classical Science" processes of observation and description, we see the search for regularities and connections between data and the formulation of probable explanations for why connections exist. Testing these "most probable explanations" is frequently done using computer models and the program describes how simple mathematical models have developed into remarkably useful predictive tools. Topics covered include: observation of the past temperatures of the earth (using oxygen isotopes in ice cores) and the present quantity of greenhouse gases, construction of a computer model of the greenhouse effect with such variables as clouds, cities and plants and testing the model by using data from the past to predict present conditions.

"Ron Nyholm never entered a room. He bubbled into it and exploded with good fellowship, mirth and happiness. Enthusiasm was the clue to his life." Provost of University College, London (Lord Annan) For many years Ronald Nyholm was a lecturer at Sydney Technical College and in 1955 he was appointed Professor of Chemistry at University College in London and in 1963 became the Head of the Chemistry Department. Sir Ronald had a deep and lasting interest in students and in the teaching of chemistry at all levels. Enjoy the process of watching: The Wizards cauldron - sublimation of dry ice; Nylon rope - polymerisation; Cloth dyeing - structure affinity relationships; Sea water flasks - aerial oxidation; Liquid oxygen - oxidation; Chromium trioxide/ethanol; Gun cotton; Pouring race; Old Nassau; Flash bulbs; Luminol and Flash bang tubes. These fascinating demonstrations by this chemistry icon, coupled with the teachers notes complete with equations and experiment notes, highlights a true Chemistry Champion as shown in The 1988 Nyholm Youth Lecture.
