He taught that a ruler must set an example to inspire people to strive for a moral life. Years after he died, students assembled his teachings into a book, the Analects, and a new school of thought developed—Confucianism. This philosophy deeply influenced China throughout most of its history.
Motivation Before students begin their Internet exploration into the history of the atom, review their present knowledge by asking questions like these: Matter is anything that has mass and occupies space.
What is an atom? An atom is the smallest particle of an element. What is an element? An element is a substance that cannot be broken down into simpler substances under ordinary conditions. Why do you think it is important to study the history of the atom?
In what ways do you think the study of matter has affected our lives? As you discuss these ideas, be aware of common misconceptions that students may have. High-school students should be able to recognize these earlier misconceptions. Greece, 5th century B.
Displaying an old map of Greece might enhance this experience. You find yourselves in ancient Greece in the presence of Leucippus and Democritus, the two philosophers credited with originating the concept of the atom.
You have the privilege to observe the two men as they work on and discuss their ideas about the atom. It is not so important for students to come up with accurate answers as to try to comprehend the era, circumstances, and particulars that might have occurred when the atomic concept was first formed.
What do you see?
What are these men like? Why are they talking about concepts? What do you think their specific ideas are about the atom? How do you think they have come to these conclusions? What tools, if any, are they using? What is remarkable about what they are doing?
Accept all answers, but ask students to offer explanations to support their views. The purpose of these exercises is to set up the lesson and establish students' level of awareness regarding the basic concepts and the critical early figures that first developed them.
This paper should serve as a good orientation about early Greek theories of the atom. As students read the specifics about Leucippus and Democritus, the five major points to their atomic concept, and the fate of their ideas until the 17thcentury, encourage them to take notes.
After students have read the article, ask them questions like these listed on The Ancient Greeks student sheet: How has modern civilization come to learn about the ideas of Leucippus and Democritus?
Since nearly all of the original writings of Leucippus and Democritus were lost, the modern world has learned of their ideas through the writings of Epicurus and Lucretius. What are the five major points of their atomic theory? They are that 1 all matter is composed of atoms that are too small to be seen and cannot be split into further portions; 2 there is a void, which is empty space between atoms; 3 atoms are completely solid; 4 atoms are homogeneous, with no internal structure; and 5 atoms are different in their sizes, shapes, and weight.
What is the significance of having a lower limit to which an atom can be divided? For atoms to change, motion is necessary.
While discussing the specific perspectives of each point, emphasize that modern science has proven the early Greeks to be incorrect about atoms having no inside voids Point 3, Rutherford or internal structure Point 4, Thomson.
Class Two First, students should use their esheet to go to and read and take notes on The Atomists: Leucippus of Miletus and Democritus of Abdera. While discussing the material, include these questions: What specific contributions did Leucippus and Democritus make in the development of their atomic theory?
In basic terms, Leucippus first developed the theory of atoms and void, and Democritus expanded upon it.
Why did Leucippus first develop the basic atomic theory in response to the Eleatics?The genomes of ancient humans can reveal patterns of early human migration (see the Perspective by Achilli et al.). Iceland has a genetically distinct population, despite relatively recent settlement (∼ years ago).
Ebenesersdóttir et al.
examined the genomes of ancient Icelandic people, dating to near the colonization of Iceland, and compared them with modernday Icelandic populations. The History of science is the study of the development of science and scientific knowledge, including both the natural and social sciences.
(The history of the arts and humanities is termed history of scholarship.) Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of.
The Development of Mathematics, in a Nutshell. Though mathematical knowledge is ancient, stretching back to the Stone Age, the evolution of mathematics to its current modern state has seen fundamental changes in concepts, organization, scope, outlook, and timberdesignmag.comt understanding the evolution of mathematical thought, it is difficult to appreciate modern mathematics in its contemporary.
Science in Ancient Mesopotamia [Carol Moss] on timberdesignmag.com *FREE* shipping on qualifying offers. Describes the enormous accomplishments of the Sumerians and Babylonians of ancient Mesopotamia in every scientific area. “In an age and field dominated by micro-histories and fragmented by hyperprofessionalism this ‘big picture’ account is a welcome addition It is a longue duree history of science, offering the reader a well-structured and eminently readable narrative that calls attention to Crombie’s styles project.
Purpose. To introduce students to the ancient theories of matter that led to the work of John Dalton. Context.
This lesson is the first of a five-part series that will broaden and enhance students’ understanding of the atom and the history of its discovery and development from ancient to .
