...Tenochtitlan, and ultimately conquered the city and empire, leaving the Aztecs as slaves working their own land to benefit the Spanish Crown. Even though the Spanish obviously seemed much more powerful, the Aztec people actually had many similarities to their conquerors. Firstly, both civilizations relied heavily on religion and made most decisions based on their religious beliefs. Yet there were also many differences in the worldviews of these people. I think that the biggest elements we can compare between the Aztec and Spanish civilizations are how their societies functioned. In many ways, their social hierarchies were similar, but also quite different. Lastly, it is important to take a look at the education received by people in each group, to better understand their societies. First, it is crucial to recognize how these two societies operated, which brings our focus...

...Abstract This paper discusses photosynthesis and how it is used by plants to harness solar energy. It also discusses semiconductor-based solar cells and how they are able to harness solar energy and convert it to electricity. This paper also compares the two types of solar energy systems and provides an overview of how the two systems are alike and how they are different. In closing, this paper will briefly explain how the laws of thermodynamics apply to each of the two energy systems. Photosynthesis Photosynthesis is a process that transfers solar energy, or energy from the sun, into a chemical energy that provides nutrients to plants and animals all over the world. Without these important nutrients, plants, animals and humans would not be able to survive on earth. “Animals and plants get energy by metabolizing nutrient molecules made by photosynthesizers.” (Mader, 2010) Semiconductor-Based Solar Cell Before discussing what a semiconductor-based solar cell is, I would first like to define a semiconductor and then explain how it is used in a solar cell type environment. A semiconductor is, “a class of materials, such as silicon and germanium, whose electrical properties lie between those of conductors (such as copper and aluminum) and insulators (such as glass and rubber).” (Seale, 2003, Semiconductor). After many years of experimenting with solar energy, scientists were able to discover that semiconductors were the main component necessary to build...

...For my opus I have decided to compare and contrast two unequivocal three dimensional statues: our treasured “Circle of Knowledge” and the famous “Statue of Liberty”. First we have the “Circle of Knowledge” which is located on the Mandeville campus of Northern Caribbean University (NCU), Jamaica. Presented as a gift from the graduating class of 2002 this towering 2.44meters statue, of a male and female student, was sculpted by Jamaica’s own, Basil Watson, who specialises in ‘human figure’. This monument appears to be a more contemporary style of sculpture that was cast from bonded bronze, giving it its firm gray hue. The Statue of Liberty was also a gift, a gift of friendship, from the people of France to the United States. This 93meters, colossal, pastel green statue of a woman is a neoclassical sculpture on Liberty Island in the middle of New York Harbour, in Manhattan. The artist responsible for this piece is Frédéric Auguste Bartholdi but Architects such as Gustave Eiffel and Richard Hunt helped with its construction. Using mediums such as copper, wrought iron and steel the construction of the statue started in September of 1875 and it opened to public viewing on October 28, 1886. Even with their extensive difference in size, the frontal exhibit of each in its own location serves as a welcoming and a reminder to its viewers. The Circle of Knowledge was explicitly designed with NCU in mind. It embodies the values and ethos of the university. This life-size, well proportioned...

...The Kingdom of Mali Prior to the emergence of the Kingdom of Mali, under the leadership of Sundiata of the Keita clan, after the decline of its predecessor Ghana, Mali had had a succession of strong leaders. It also had established strong regional trade links. The ancient Malian kingdom of Jenne-Jeno was reputed by archaeologists to have its roots in and around 200 Years BC. Mali only began to lose its power and influence in the 16th Century. Prior to its eventual collapse it was the second largest state in the world after the Asiatic Mongol Empire. Jenne’s strategic position made it an important crossroads for both north and south trade. Highly crafted fragments of pottery, iron work and jewelry have been discovered in the region. This makes it highly likely that there were imports of iron ore, stone grinders and beads into Mali. Also the origins of Mali lie in the Mandinka people who originally lived in the upper reaches of the Niger and Senegal rivers. They lived in small villages which were called Dugu. The chiefs of each village called themselves Dugutigi. These villages by the end of the 12th Century had formed themselves into the state of Kangaba. With the breakup of the Ancient Kingdom of Ghana, partly caused by raids led by the Almoravid Berbars from the north coupled with dwindling gold supplies at around the start of the 12th Century, smaller states such as Tekrur and Sosso competed to fill the power basin left in regions west of the Upper Niger. One of the main reasons...

...Tutor Date Ancient Greek Heroes vs. Modern Heroes Introduction The word hero brings to mind different things to different people, since people tend to have different concepts of heroism. This is particularly the case with regard to the concept of heroes in ancient and modern societies. As times have changed, the definition of heroes has also changed, in keeping with the changes in the modern society. However, ancient and modern heroes do share some similarities, which act as the basis of heroism regardless of one’s perspective. In view of this, a hero can be described as a courageous person, who deliberately sets out to conquer obstacles for the benefit others or one who performs extra ordinary feats. The aim of this paper is to compare and contrast ancient Greek heroes with modern heroes, for the purpose of understanding both concepts of heroism. Differences There a few differences between modern and ancient Greek heroes, one of them being the religious background of the ancient Greek heroes. In Greek mythology, heroes were usually religious figures, specifically demigods. They were usually born from liaisons between mortal and immortal parents. These heroes were favored by the gods, hence were able to accomplish supernatural tasks, which were beyond the abilities of normal men. Hercules’ mother for instance was a mortal, while his father Zeus was a Greek god, who disguised himself as her husband. As a result, Hercules was a demigod, and was able to accomplish extraordinary...

...An electromagnetic wave of a frequency used for long distant communication. 4. Explain the difference between a transverse wave and a longitudinal wave, and give examples of each. In a longitudinal wave, the vibration travels in the same direction that wave travels. Examples of longitudinal waves include: Sound, p-waves (earthquakes) In a transverse wave, the vibration direction is perpendicular to direction that wave travels. Examples include: Light/electromagnetic, (radio, microwave, xray, etc.), water waves, swaves (earthquakes). The major difference between longitudinal and transverse waves is their direction. Longitudinal waves move left to right while transverse waves move up and down. 5. Compare and contrast: light waves vs. sound waves Light waves are transverse and sound waves are longitudinal. Light waves can travel through a vacuum but sound waves cannot. Speed of light is nearly 300 million m/s while sound has a speed of about 340 m/s. 6. What changes the pitch of sound? The frequency of vibration. Faster vibration would cause a higher pitch while slower vibration would cause a lower pitch. 7. Explain how different factors affect the speed of sound? Speed of sound depends on factors such as altitude, humidity, and temperature because sound waves need molecules to collide in...

...METAPHOR POEM I am #1 Directions: Write a short poem of at least 6 lines entitled, “I am #1.” Make it look like a poem but do not rhyme it – remember form is meaning. You will be creating a picture in words of yourself (imagery & metaphor). 1. What color are you? 2. What beverage represents you? 3. How do you act in a crowd? 4. What contrast describes you? 5. What chair represents you? 6. What time of day best describes you? 7. What musical instrument best describes you? EXAMPLE: I am a blue bubbling e f f e r v e s c e n t soda-pop. I stand out in the midst of people sparkling brilliantly. A bear grrrowling in the morning mirror… but a cuddly cub purrrring by evening is me. The stars twinkle and shine for me as I gently rock back and forth, back and forth on the front porch swing. My hearts beats like a drum in my chest – THRUMP, THRUMP, THRUMP, keeping time to my own beat. TWO-TONE POEM What color are you? A crazy question, perhaps. Most of us are at least two-tones. Psychologists tell us that certain colors trigger certain feelings or moods in many people. Some colors are “warm” while others are “cool.” Some colors attract attention; others blend in with their surroundings. Our own interpretation of our feelings about colors, a long with our self knowledge can be a good combination to start a “two-tone” poem. EXAMPLE: My Two Colors Part of me is brilliant yellow Lively and vivacious, Bouncy...

...did happen on July 4, 1776? The Continental Congress approved the final wording of the Declaration of Independence on July 4, 1776. They'd been working on it for a couple of days after the draft was submitted on July 2nd and finally agreed on all of the edits and changes. July 4, 1776, became the date that was included on the Declaration of Independence, and the fancy handwritten copy that was signed in August (the copy now displayed at the National Archives in Washington, D.C.) It’s also the date that was printed on the Dunlap Broadsides, the original printed copies of the Declaration that were circulated throughout the new nation. So when people thought of the Declaration of Independence, July 4, 1776 was the date they remembered. In contrast, we celebrate Constitution Day on September 17th of each year, the anniversary of the date the Constitution was signed, not the anniversary of the date it was approved. If we’d followed this same approach for the Declaration of Independence we’d being celebrating Independence Day on August 2nd of each year, the day the Declaration...

...SIMPLE SCIENCE EXPERIMENTS HANS JURGEN PRESS 1. Astronomy Image of the Sun Place a pair of binoculars in an open window in the direct path of the sun’s rays. Stand a mirror in front of one eyepiece so that it throws an image of the sun on to the opposite wall of the room. Adjust the mirror until the image is sharp, and darken the room. You would risk damaging your eyes if you looked directly at the sun through binoculars, but you can view the bright disc on the wall as large and clear as in the movies. Clouds and birds passing over can also be distinguished and. if the binoculars are good even sunspots. These are a few hot areas on the glowing sphere, some so big that many terrestrial globes could fit into them. Because of the earth’s rotation, the sun’s image moves quite quickly across the wall. Do not forget to re-align the binoculars from time to time onto the sun. The moon and stars cannot be observed in this way because the light coming from them is too weak. 2. Sun clock Place a flowerpot with a long stick fixed into the hole at the bottom in a spot, which is sunny, all day. The stick’s shadow moves along the rim of the pot as the sun moves. Each hour by the clock mark the position of the shadow on the pot. If the sun is shining, you can read off the time. Because of the rotation of the earth the sun apparently passes over us in a semi-circle. In the morning and evening its shadow strikes the pot superficially, while; it midday, around 12 o’clock...

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses.
