Senior Science

Lifestyle Chemistry Take a walk through your kitchen, bathroom and laundry and note the wide range of commercial products that clean and protect all kinds of surfaces from the porcelain bathtub to the skin of your face. Each cleaning or protective agent is specifically designed to suit a particular surface material or fabric. The variety of consumer products we use in our everyday lives is a result of the explo- sion in knowledge over the past 50 years of many chemical substances and their inter- actions. Development of the petroleum industry was accelerated during the Second World War due to the need to develop substitutes for raw materials such as cotton and rubber. The need to control disease and ease pain among wounded soldiers and civilians stimulated new branches of medicine and the pharmaceutical industry. Our understanding of chemicals and their interactions has led to the development of chemical technology. Accurate control of chemical processes allows industry to produce cosmetics and pharmaceuticals under precisely controlled conditions so that chemicals are produced that serve a specific purpose and have few side effects. The challenge for the chemical industry is to leave as few unwanted effects on the environment as the cosmetics and pharmaceutical industries have managed for the human body. Part of that challenge is fulfilled by the production of biodegradable detergents and cleaners that release minimal phosphates into our waterways.

Medical Technology - Bionics

Many people today live active and productive lives because of biomaterials and biomedical devices. These either temporarily or permanently replace missing or faulty parts of the body. These materials and devices can have a significant impact on a person’s quality of life and the length of life. ** Bionics ** is usually taken to mean designing electronic and mechanical devices that copy the behaviour of parts of the human body. The term was originally applied to a variety of scientific projects involving biological systems, engineering systems, and artificial intelligence. Many of the projects used biological principles to solve engineering problems.

This topic explains how mobile phones, radios, telephones, televisions, satellites and satellite dishes work. You will understand how energy is transformed so that information can be transmitted from one place to another. Many information systems rely on digital transmissions of light, radio waves or microwaves using electricity. The importance of the electromagnetic spectrum for information transmission is addressed as is the difference between AM, FM and microwave communication. You will appreciate the purposes of different satellite orbits and identify the type of satellites used for live telecast. Studying how a fax machine works will enable you to better understand how information can be transmitted in the form of electrical impulses. Finally you will explore the properties of optical fibres using light and appreciate how they transmit information in telecommunications using infra–red radiation. Even if you are a technophobe, you should enjoy Information systems and appreciate the advances in technology that now allow us to communicate across the globe.
