To find the best insulating material by measuring how quickly water cools
An investigation to see which is the best insulator Aim: To fin the best insulating material by measuring how quickly water cools Prediction: I predict that the plastic on coconut will be the best insulator. Theory: My reason for choosing plastic and coconut as the best insulator is because company's use plastic when producing things to contain heat. An example of this is a kettle, which use's plastic to keep the heat in so that it does not escape. Plastic is also used on the handles of pot's and pans, which deal with a lot of heat when cooking. Coconut is also a good insulator because when you cut down a coconut from the palm tree there is a lot of liquid inside of it. This liquid is kept inside of with out having the liquid evaporating. When you combine the two together you get the best of both. You are also trapping air in between the two materials. There are also three ways heat can travel these as conduction, convection and radiation. Conduction: This is the process in which heat is transferred from molecule to molecule by vibrating into each other hence passing the energy. All materials allow energy to pass through them by conduction. The particles of a gas are spread out making them poor conductors of energy because they are so spread out. Convection: If a temperature difference arises within a liquid or a gas, then fluid motion will almost certainly occur. This
History Of The Model Theatre
The Model Toy Theatre The Toy Theatre, also called the Paper Theatre and Model Theatre is a form of Miniature Theatre dating back to the early 1800s in Europe. Toy theatres were often printed on paperboard sheets and sold as kits at the concession stand of an opera or theatre. Toy theatres were assembled at home and performed for family members and guests, sometimes even with live music. Toy Theatre saw a drastic decline in popularity with a shift towards realism on the European stage in the late 19th century, and again with the arrival of television after World War 2. Toy Theater has seen a comeback in recent years among many puppeteers, authors and filmmakers and there are numerous international toy theatre festivals throughout the Americas and Europe. In the first half of the 19th century more than 300 of London's most popular plays saw issue as toy theatres. When realism was introduced, Model Theatre's started to use 3D models. Other countries produced model theatres, but the prints from Denmark and Germany were some of the most outstanding. The model theatre really started to be known with Benjamin Pollock. He was born in1856 in Hoxton, which was in the poor quarter of London. He and his father were in the fur trade which was a family business. He would often visit a shop down the road which belonged to John Redington, who among many jobs, like a Tobacconist was a
Create and sell an accessory collection (starting a small business)
Topic: Create and sell an accessory collection (starting a small business) Hypothesis: To what extent can determination help you to develop the necessary skills to handle the organization and managing of a small company? Tutor's name: Gabriela Flaiban Area Leader's name: M r Harvey Mc Gough Area of interaction: Homo Faber Student's Name: Victoria Ocampo Level 5 "A" Year: 2003 Personal Statement Introduction Starting to work Next steps Bibliography Annexes The main reason I've chosen this topic is because as you will also read in the introduction, making accessories is something I really like doing; It is the first time I can accomplish a school task that has been given to me, doing something that I enjoy. It is just perfect! It will not only help me with my school life, but it could also be the beginnings of a promising future. The aim of my project, parallel to the fact of making accessories and selling them is to see if determination and skills are enough to start a business of my own. I do not believe it would be difficult to design and sell the new collection. What I have to see is how I will finance the whole process. But I am really enthusiastic about it and I will really try hard to put all my ideas into action. Since we had to do a project to pass the middle age program I tried to do a project that nobody else has ever done and something I
Product Design - analysis of the XBox 360
Introduction: The reason that I have chosen the Xbox as the item to do this project on is because of the following reasons. * It has several add-ons which can be used and are used on a constant basis * I am an Xbox owner myself and know its pros and cons and know a severe amount about it. Along with these reasons the Xbox 360 has an expandable memory for music and photos. On the Xbox you can save games to the hard drive which comes in very handy if your and gets scratched this is how you resolve it without having to buy a new game. The expandable memory on these consoles depends on the type of Xbox bought. For example the elite console has an expandable memory up to 250 GB. This 250 GB is for also watching and recording sky on just like the new sky plus box. You can record movies and keep on your hard drive to watch again and again. Aesthetics: The Xbox aesthetics are different depending on which version you buy. The Arcade and Premium versions of the Xbox 360 are very similar with a smooth rectangular shape with rounded edges and a big circular button in the centre with small green lights surrounding it. One is black (Premium) and one is white (Arcade) in colour with some green and silver areas throughout. The arcade is the cheaper of the two as it doesn't have the same attachments and variety of facilities that the elite has but is more well known as the colour of
Types of Materials for Jewelry
Types of Materials for Jewelry * Titanium Titanium is a silver colored element metal, which is about half the weight of Stainless Steel. This weight difference can be a big advantage if you like the look of really thick jewelry but your piercing is gets aggravated by heavy jewelry. Titanium jewelry is an excellent choice to be used in new piercings as it is hypoallergenic and is normally accepted by the body very well. A new piercing done with Titanium jewelry will usually heal up much faster too. Healing quickly is ideal because the longer a piercing takes to heal the longer it is susceptible to infection and more chance it has to migrate through the skin. * 8ct Yellow Gold 8 carat Gold is also a very good material for body jewelry and is readily accepted by most people's body piercing, but it does not work well for all people. It is softer then metals such as Titanium, Niobium and 316L steel and some peoples skin can actually discolor the gold but it can easily be repolished back to its former lustre. Gold Body jewelry looks great and is very popular with "Gold People". 9ct gold only contains about 30% gold and therefore not suitable to be worn in most peoples body piercings. * Niobium Niobium is an element metal with similar properties of Titanium but its is not as light. It is Hypoallergenic so it works great for body piercing and the other exceptional property
Casing Research
Casing Research PLYWOOD Plywood is a manufactured board. It is used to case speakers. Birch-faced ply is a light coloured, high-quality plywood that colour-stains and varnishes easily. CHIPBOARD Chipboard is also a manufactured board. It is cheap and will not warp or curl. Chipboard comes in two forms, plain and woodgrain, both of which are usually coated in plastic 'foil' or veneered to improve the finish and looks. MDF MDF (Medium Density Fibreboard) is another manufactured board. It used to fabricate boxes, and close-textured MDF is cut and sanded to make moulds for vacuum forming plastics. MDF must be glued using PVA carefully and precisely, and requires coating with paint many times to give a good finish, as it absorbs liquids readily. Mild Steel Mild steel can be found in many different forms. Sheet steel, for example, is made into casings and a variety of brackets an fixings. Bright drawn steel is made into round, square, tubular, angled and flat bar versions. Mild steel can be cut and shape into components that are to be permanently fixed to the product. This is done by welding, brazing and using silver solder. Aluminium Aluminium is a light metal in its elemental form. It comes in sheet, bright drawn and mild forms (similar to steel) and can be cast. If a strong lightweight product is needed, aluminium is the only choice. Aluminium can be joined
Communication: the Key To Designing Safely.
COMMUNICATION: THE KEY TO DESIGNING SAFELY J. MacKenzie, A.G.F. Gibb & N.M. Bouchlaghem Civil Eng. Dept. Loughborough University, UK [email protected] ABSTRACT We have come a long way since the first recordings of workplace related incidents and over the years the UK construction industry has witnessed a steady decline in the number of accidents and fatalities. However, compared to other industries these figures are still unacceptably high. Formally, safety held its domain firmly within the construction phase where it was perceived most accidents were caused. Over the last twenty-five years fundamental changes to UK legislation have seen health and safety being addressed in the design phase. The initial response is that the CDM Regulations have raised awareness of health and safety issues throughout the industry. However, for many designers the application of such regulations is intuitive and relies on the attitude and behaviour of the designers towards safety and their ability to communicate the identifiable risks effectively. Encouraging designers to think safely will only flourish in an environment where technical information is freely available. This paper will address some of the problems associated with CDM and look at the importance of communication and possible ways of enhancing information flow.

materials for toysTYPES OF MATERIALS
TYPES OF MATERIALS Michael.h. Wood is a remarkable natural material. It is strong and relatively stiff and light. Its properties compete well with those of artificial materials. The fastest bomber in World War II, the British De Havilland Mosquito, was made of wood. When German intelligence discovered that the Allies were making aeroplanes out of wood, they thought that it was because supplies of metal had run out-not realizing that wood had been carefully chosen partly because it had excellent properties for this design. Wood remains the preferred material for many applications in the building industry throughout the world, and also for much furniture. Stone is another natural material, once used for making simple tools and weapons, and subsequently almost exclusively for buildings and sculptures. Among the earliest materials to be put to use by human beings were ceramics, in the form of the clays used in pottery. Archaeologists date early civilizations by the pottery associated with them. Ceramic materials are chemical compounds of one or more metallic elements with oxygen or with other elements such as nitrogen. For a long time ceramics were mainly used for plumbing or for cooking or eating utensils, but relatively strong engineering ceramics have now been developed with good mechanical properties, and others, called electro ceramics, are essential for a wide range of
Find the best material to make the shoelace for a pair of running shoes.
Introduction I will study the properties of materials and consider how these properties affect the choice of materials for particular sports footwear. I will be investigating: * Grip * Density and Floatation * Weathering and Chemical Corrosion * Resistance to Wear * Strength * Stiffness * Collisions Properties required for footwear Heel Height The heel height of a running shoe is another viable in a fitting. Athletes with short calf muscles or a history of Achilles tendonitis should look for the highest heel available. So if somebody can't easily touch their toes from a standing position they should benefit from increased heel height. Heel Counter The heel counter is found in the back part of the shoe. It functions to provide support for the heel bone on ground contact. The counter should be as rigid as possible. Shock Absorption A training shoe should provide as much protection to your foot as possible. The shock absorption layer should provide good cushioning, without completely collapsing. It may be difficult to determine how good a shoe absorbs shock without running in it. Athletic magazines run these tests on shoes, and are good for referring information about training shoes. Sole flexibility The front part of the sole (where the foot bends) should be flexible. Too stiff a sole means wasted effort. If you cannot flex the sole easily, the sole is
