Science, Foundation For Future Knowledge What is science? The junior high textbook defines sci- ence as being a body of organized knowledge about the things and forces in the universe, based on experimenta- tion. By things they mean matter or anything that has weight and occupies space (has volume). Almost everyone has some understanding about matter but when it comes to forces, few people can accurately define it or compre- hend all the different types of forces. What causes forces? Energy. One of the least under- stood forms of energy is that of light. What is this mysteri- ous substance that travels 186,000 miles per second? At this speed, in the time that it takes you to say 186,000 miles per second you could have traveled around the earth ' s equator seven and a half times! Light also has weight (particle characteristics) and these packets of light energy are called photons. Scientists from NASA have calculated that these photons of light streaming from the sun (the solar wind ) pushed the sateUite Vanguard I off course about one mile year. Phy- sicists also know that light is deflected by gravitational fields. These facts seem to point out tliat light is a parti- cle. Is light both a wave and a particle? The students in science today are the scientists of tomorrow who will find the answer to this and many other questions. They are preparing themselves for the scientific and technological world of the 21st century. David Blevins is busy completing his experiment in Chemistry lab. Larry Biehl is learning how different lenses refract light in Physics class. Mr. Graham demonstrates an oscilloscope to his Physics class.

Histories Of The World, The U.S. And Indiana The need for economic knowledge among American citizens has never been greater. Increasingly, citizens are called upon to participate in making decisions that are of an economic nature, whether it be deciding how best to spend or invest one ' s own hmited income, or deciding economic matters affecting the whole community. In fact, it may be said that people devote more time to economics than to anything else that concerns their everyday lives. In economics it ' s important to learn about our own economy. We learn about a free economy, its meaning, characteristics, and purposes. Within our economy we learn what to produce and how to produce it. Within the realm of production we learn about the problems and nature of money, banking, credit, farm problems, labor, capital, prices, resources, trade, and government in our economic lives, just to give a partial list. While learning about our economy, we compare it to other economic systems. John Shellenbarger w atches as Nancy Stanley casts her ballot in the election sponsored by the Government classes.
