... I could go on to find the percentage error. The equation I used was, error divided by the accepted ratio times 100. For example, if I took the error of the experimental ratio for the paper towels, which was 0.12. I took that and divided it by the accepted ratio giving me .03821651. Then I multiplied that by 100 giving me about 3.14. Using these steps I found the percentage error for all of the objects measured. The next step was to graph the results. I was able to do this very easily with spreadsheet. I typed in all of my data and the computer gave me a nice scatter block graph. I also made a graph by hand. I set up the scale by taking the number of blocks up the side of my graph and div ...

... rate, aids and HIV through the use of needles, dependence, tolerance, addiction, and can cause psychosis. The use of Meth is going up. In 1995, 3.9% of high school seniors had used it. That's an increase of 2.7% since 1990. 8 out of 10 people who try Meth will become addicted. Famous people who have done Meth include- Chris Farley, John Belushi, and Mick Jagger. The cost of doing Meth is very high too. A user can spend up to $100 a day. And sometimes, spending $400-$500 to support an addiction is not unusual. The penalties are very severe for those caught with Meth. Possession of any quantity of Meth can carry up to 7 years in prison. Distributing Meth carries a penalty of u ...

... the breakdown of the religious-infested societies that plagued the world. This became very important to everyone involved, which proved to be more people than expected. The ‘heroic model’ was an opening for scientist and others to express their opinions without the fear of being ostracized and labeled as a blasphemer. These people were no longer look down upon as sinners, against God and religion, yet they were praised for bring truth and secularity to the world. “Facts” no longer were infested or influenced by religion, the truth was the real truth. “It replaced the fear and anxiety that nature once evoked with hope inspired by an ordered, harmonious, ...

... made private forecasts for small areas. Meteorologists are people who interpret the weather, the reason I don't say predict the weather is because even though all forecasters have the same information and data at their fingertips, the way that they interpret what is in front of them can be different. Meteorologists receive information from various sources, but their interpretation of the data determines the accuracy of their prediction. Someone might ask, "If forecasters have so much information on a particular area; how could they predict a flawed forecast ?" The answer to that question lies in the fact that any one of a number of weather conditions may ruin a forecast. A fas ...

... planetary motion. The three most popular instruments which used were quadrant, armilla, and triquetrum. All furnish some measure of the position of the heavenly body. It took an endless amount of mathematical calculations to come up with the Copernicus' theory. He had to find out how fast the Earth spins around the Sun, and how far the Sun is. He also had to calculate the length of the orbit of the Earth. People use math in every walk of life. In our days everything is related to math, and Copernicus used his knowledge of mathematics to provide the human kind with an important discovery. Only a small amount of people are interested in Copernicus' work. If it wasn't for Coperni ...

... would not be easy at all to put and keep the files in some sort of alphabetical sequence. Currently the database is pen-and-paper based, which may be cost effective but is very time-consuming when compared to a computer-based database. Say you have a paper-based database. If one of your clients move house or get married, you would have to create a whole new record because of the altered information. And say it was a family who moved residence, and then after you made the new records the parents got married. It would cause a lot of hassle and waste a lot of time, wouldn’t it? The doctor would get annoyed searching for people’s files and they would take longer to get through ...

... become one of the many risks that society must face if it would enjoy the benefits of modern technology. Imagine a world without . That would mean no proper means of communicating, no Internet, no video games. Life would be extremely difficult. Adults would have to store all their office work paper and therefore take up an entire room. Teenagers would have to submit course-works and projects hand-written. All graphs and diagrams would have to be drawn neatly and carefully. Youngsters would never have heard of 'video-games' and will have to spend their free time either reading or playing outside with friends. But thanks to British mathematicians, Augusta Ada Byron and Charles Babbage, our ...

... as well as through their effect on humans in sometimes subtle ways. The inherent properties of wood have always made it attractive as a versatile resource but there are other, more subtle ways in which it affects people. The tropical rainforests, responsible for producing most of the earth's breathable air, have been given the lofty title of "lungs of the Earth," and as stated by the Canadian Encyclopedia Plus '93, "forests provide an additional, although intangible, benefit: the opportunity for renewal of the human spirit" (CAN ENCYC). Once humanity accepts these facts, we open ourselves up to profound responsibilities regarding their protection. Unfortunately for both ourselves and our ...

... string. 6. Insert the transfer pipette (cut off top) about one third of the way into the tubing. 7. Tie a knot securely around the transfer pipette. Leave the extra string. 8. Add two transfer pipettes (two squirts) of the Gatorade solution to the tubing. 9. Add two transfer pipettes (two squirts) of the starch solution to the tubing. 10. If you spilled any solutions while transferring, carefully rinse the tubing. 11. Fill the cylinder with distilled water to about 2.54 cm from the top. 12. Place the tubing into the cylinder of water. 13. Rest the apparatus against the ring stand. 14. Note the height of the water in the tube. 15. Record the time the tube was placed into the cylinder (it wi ...

... like to know something’s I can do to lessen the effects on our environment. What is acid rain? Acid rain is the name commonly given to the deposition of a cocktail of acidifying compounds to soils, surface waters and buildings. These compounds arise mainly from the combustion of fossil fuels. In some parts of the United Kingdom, natural ecosystems have a significant acid-neutralizing capacity and acid rain has little impact on them. In other parts, the neutralizing capacity is limited, and terrestrial and aquatic ecosystems are sensitive to acid deposition. In acid-sensitive areas, acid rain degrades the terrestrial environment and causes damage to plants and the soils in which they g ...
