This is a sculpture by the contemporary artist Dereck Kinzett. The title of this sculpture is “Guardian Angel”. Kinzett use chicken wire to create his life size sculptures. He was born in 1966. Kinzett received his diploma in art and design in 1984. He spent his childhood living in Dodington Park‚ Gloucestershire. Kinzett’s work strongly draws your interest‚ is modest and natural. His work never about impressing people but pleasing himself and his customers. Derek Kinzett sculptures are usually purchased

their sources‚ and interactions with moving charged particles. To accomplish this lab‚ we will do 5 stations‚ and we need these instruments: several magnets which have different sizes‚ a board‚ a piece of alumium metal‚ a battery‚ two pieces of wires‚ a nail‚ a 180cm copper pipe. Station1‚ we tilt a smooth board and roll the neodymium down it‚ the track is curve because the magnetic field of the earth is affecting the magnet. The effect most pronounced when the magnet is rolling NS/SN. Station

world of technological advancement. New technologies emerge each and every day to make our life simpler. Despite all these‚ we still rely on the classical and conventional wire system to charge our everyday use low power devices such as mobile phones‚ digital camera etc. and even mid power devices such as laptops. The conventional wire system creates a mess when it comes to charging several devices simultaneously. It also takes up a lot of electric sockets and not to mention the fact that teach device

The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

How to Solder First a few safety precautions: * Never touch the element or tip of the soldering iron. They are very hot (about 400°C) and will give you a nasty burn. * Take great care to avoid touching the mains flex with the tip of the iron. The iron should have a heatproof flex for extra protection. An ordinary plastic flex will melt immediately if touched by a hot iron and there is a serious risk of burns and electric shock. * Always return the soldering iron to its stand when

called a Solenoid‚ Which consists of a core of iron and then wire is wrapped round it. Prediction I predict that as the current carried in the wire gets stronger‚ so will the magnetic field surrounding the electromagnet. Therefore‚ I think that the amount of paper clips picked up will increase as the voltage gets higher until the electromagnet can’t pick up any more paper clips. I also predict that the more coils wrapped round the wire creates a bigger magnetic field allowing more paper clips to

information is sent across one wire‚ one data bit at a time‚ its called serial. Every computer on the face of the earth has some form of serial communications connector on it‚ whether internally or externally. Most people are familliar with the ’D’ shaped 9-pin connector on the back of thier computer. This is a serial connector. The typical 9-pin ’D’ shaped connector on the back of your computer uses 2 loops of wire (1 in each direction) for data communication‚ plus additional wires to control the flow of

(3) Using your wire‚ dip it into the beaker containing Hydrochloric acid (4) Place it into the flame for a few seconds; this is the cleaning method to avoid contamination of other solutions. If the Bunsen burner flame does not change colour‚ then your wire is clean and you can proceed to dip it into a metal salt. (5) Dip your wire into a metal salt either the nitrate or chloride and place the wire onto the tip of the blue flame. (6) Observe the change
