QUES: If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

QUES: How can you describe your location? You might use a familiar system. You might say, 'I live at 1234 Main Street, Springfield, Ohio.' You could also say, 'I live right behind the Elementary School.' This method uses the school as a point of reference. Another example is, I am at the corner of Maple Street and Main Street. Both streets may be a good reference for anyone living in your town. Scientists must be able to pinpoint a feature they are studying. Scientists use a special system to describe locations. They use latitude and longitude as a reference. Lines of latitude and longitude form a grid. You may have used a grid system while doing graphing. This grid is centered on a reference point. Zero latitude is the equator. Lines of latitude run east to west. They divide the Earth from North to South. Lines of longitude run from north to south. They divide the Earth from East to West. Zero longitude runs through Greenwich, England. You may have heard the term, Greenwich Mean Time, or GMT. The system of latitude and longitude works well for objects that do not move.

QUES: Chinese Influences: The Japanese were forced out of the Korean peninsula in the sixth century, but not before the Koreans had bequeathed to the Yamato court copies of the sacred images and scriptures of Chinese Buddhism. Just as Christianity introduced Mediterranean culture into northern Europe, so Buddhism brought Chinese culture into Japanese society. Throughout the seventh and eighth centuries numerous Japanese monks, scholars, and artists made the perilous trip west across the Sea of Japan to study Chinese religion, history, music, literature, and paintinglater to be brought back for further development in Japan. An outstanding figure of this time was Prince Shotoku, who in 604 developed the "Seventeen-Article Constitution," outlining a code of human conduct and the ideals of state as a basic law for the nation. He also established relations with the Sui dynasty in China. Through him, the Japanese imperial court developed Chinese patterns of centralized government, with its formal bureaucracy of eight court ranks. The Chinese calendar was used to calculate the year of Japan's foundation by counting back the 1,260 years of the Chinese cosmological cycle. Thus, 660 b.c. is still the official date celebrated nationwide. At this early stage in its history Japan was already (for the most part) only nominally ruled by the emperor. De facto power was exercised by the militarily and economically strongest family. The Sogas had promoted Buddhism as an imperially sanctioned counterweight to the native Shinto religion, along with the new Chinese customs, to weaken the influence of their more conservative rivals. But they in turn were ousted in a.d. 645 by Nakatomi Kamatari, founder of the great Fujiwara clan, which was to rule Japanese affairs for hundreds of years and provide prominent advisers to the emperor even up to the 19th century.
