The Singapore Science Centre is located on a six-hectare site in Jurong. At the centre, we can discover the wonders of science and technology in a fun way. Clap your hands and colorful bulbs will light up. Start a wheel spinning and it will set off a fan churning. It is a place to answer our curiosity and capture our imagination. The centre features over four hundred exhibits covering topics like solar radiation, communication, electronics, mathematics, nuclear energy, and evolution. It aims to arouse interest in science and technology among us and the general public. The centre is the first science one to be established in Southeast Asia. It was opened in 1977 and it now receives an average of one thousand two hundred visitors a day. The exhibits can be found in four exhibition galleries. They are the Lobby, Physical Sciences, Life Sciences and Aviation. These exhibits are renovated annually so as to encourage visitors to make return visits to the centre. Instead of the usual “Hands off’ notices found in exhibition halls, visitors are invited to touch and feel the exhibits, push the buttons, turn the cranks or pedals. This is an interesting way to learn science even if you hate the subject. A Discovery Centre was built for children between the ages of three and twelve. This new exhibition gallery was completed in 1985. Lately this year a stone-age exhibit was built. It shows us about the animals and people which were extinct.

Today we take electricity for granted and perhaps we do not realize just how useful this discovery has been. Steam was the first invention that replaced wind power. It was used to drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air was the next invention that provided power. Exploded in a cylinder, it drove a motor engine. Beyond these simple and direct uses, those forms have not much adaptability. On the other hand, we make use of electricity in thousands of ways. From the powerful voltages that drive our electric trains to the tiny current needed to work a simple calculator, and from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a doorbell, all are powered by electricity. An electric current can be made with equal ease to heat a huge mass of molten metal in a furnace, or to boil a jug for a cup of coffee. Other than atomic energy, which has not as yet been harnessed to the full, electricity is the greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted. It travels so easily and with incredible speed along wires or conductors that it can be supplied instantly over vast distances. To generate electricity, huge turbines or generators must be turned. In Australia they use coal or water to drive this machinery. When dams are built, falling water is used to drive the turbines without polluting the atmosphere with smoke from coal. Atomic power is used in several countries but there is always the fear of an accident. A tragedy once occurred at Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked, which caused many deaths through radiation. Now scientists are examining new ways of creating electricity without harmful effects to the environment. They may harness the tides as they flow in and out of bays. Most importantly, they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as yet improvement in the capacity of the solar cells to create more current is necessary. When this happens, electric cars will be viable and the world will rid itself of the toxic gases given off by trucks and cars that burn fossil fuels.

WAYS TO IMPROVE YOUR MEMORY
A good memory is often seen as something that comes naturally, and a bad memory as something (34) _______ cannot be changed, but actually there is a lot that you can do to improve your memory. We all remember the things we are interested in and forget the ones that bore the US. This no doubt explains the reason why schoolboys remember football results effortlessly but struggle (35) _____ dates. from their history lessons! Take an active interest in what you want to remember and (36) ______ on it consciously. One way to make yourself more interested is to ask questions — the more the better! Physical exercise is also important for your memory because it increases your heart rate and sends (37) ________ oxygen to your brain, and that makes your memory work better. Exercise also reduces stress, which is very bad for the memory. The old saying that - eating fish makes your brain may be true after all. Scientists have discovered that the fats found in fish like tuna, sardines, and salmon – (38) __________ in olive oil - help to improve the memory. Vitamin-rich fruits such as oranges, strawberries and red grapes are all good - brain food, too. (Source: —New Cutting Edge, Cunningham, S. & Moor. 2010. Harlow: Longman)
