...developed for science. In this global economy, it is essential that Michigan students possess personal, social, occupational, civic, and quantitative literacy. Mastery of the knowledge and essential skills defined in Michigan’s Grade Level Content Expectations will increase students’ ability to be successful academically, and contribute to the future businesses that employ them and the communities in which they choose to live. Reflecting best practices and current research, the Grade Level Content Expectations provide a set of clear and rigorous expectations for all students, and provide teachers with clearly defined statements of what students should know and be able to do as they progress through school. PHYSICAL SCIENCE LIFE SCIENCE EARTH SCIENCE Development In developing these expectations, the K-7 Scholar Work Group depended heavily on the Science Framework for the 2009 National Assessment of Educational Progress (National Assessment Governing Board, 2006) which has been the gold standard for the high school content expectations.

...and an emphasis on local planning efforts to promote efficiency and effectiveness. The desire to improve student achievement was there, but the focus on content-that is, a comprehensive, specific vision of what students actually needed to know and be able to do-was lacking. Standards are a bold initiative. Through content standards in the core subjects, California began to redefine the state’s role in public education. For the first time, the knowledge and skills that students needed to acquire were explicitly stated for the most part by grade level, although science standards at the high school level were organized by discipline. The standards are rigorous. Students who master this content are on a par with those in the best educational systems in other states and nations. The content is attainable by all students, given sufficient time, except for those few who have severe disabilities. We continue to regard the standards as firm but not unyielding; they will be modified in future years to reflect new research and scholarship. Standards describe what to teach, not how to teach it. Standards-based education maintains California’s tradition of respect for local control of schools. To help students achieve at high levels, local...

...Moon as known as our Earth’s only natural satellite is indicated by Rick Carlson in recent research to have an age of between 4.40 and 4.45 billion years, which is not long after the origin of the Earth. However, the origin of the Moon is still not defined and further research on this topic is continuous. The exploration of formation of the Moon is gradually per fected by the various proposed theories started from 1878 to nowadays. This research essay will discuss both the past and present hypotheses of origin of the Moon. The past hypotheses also known as “The Big Three” referring to Fission, Capture and Accretion hypotheses are popular in different times and centuries before the Apollo mission flew in 1972 (Tyson, 2000). However, the study on the moon rock brought by Apollo’s program gives unavailable clues for “The Big Three”(Tyson, 2000). Nowadays, the Giant Impact Hypothesis is regarded as the most leading theory that is most accepted in present. Nevertheless, it is widely accepted, some studies supported this theory; others may create new theory to challenge this Giant Impact Hypothesis, which make this hypothesis still arguable. However, whatever these hypotheses failed or will achieve, they bring a better understanding on the formation of planet’s satellites in our Solar System (Zhong, 2013), which is instrumental for further study on planetary science and even galaxy. The Big Three------The past hypotheses • Fission Hypothesis The Fission Hypothesis was proposed by George...

...of Gods and Earths, sometimes referred to as NGE or NOGE, the Five-Percent Nation, or the Five Percenters is an American organization founded in 1964 in the Harlem section of the borough of Manhattan, New York City, by Clarence 13X, a former student of Malcolm X, who left his mosque because he disagreed with the Nation of Islam over the nature and identity of God.[1] Members of the organization call themselves Five Percenters, which reflects their belief that ten percent of the people of the world know the truth of existence, and those elites opt to keep 85 percent of the world in ignorance and under their controlling thumb. The remaining percentage are those who know the truth and are determined to enlighten the rest. They are the Five Percent Nation.[1] Initially, the Nation of Gods and Earths was viewed as little more than an off-shoot of the Nation of Islam (NOI). However, while the Nation of Gods and Earths has been characterized as an organization, an institution, a religion, or even a gang, representatives of the Nation teach that it is a way of living. The New York City areas of Harlem ("Mecca") and Brooklyn ("Medina") are named after notable Islamic cities by members of the organization.[2][3] The Nation of Gods and Earths teaches that Black people are the original people of the planet Earth, and that they are the fathers (Gods) and mothers (Earths) of civilization.[1] The Nation believes that the science of Supreme Mathematics is the key to understanding man's relationship...

...knowledge includes concepts, principles, facts, laws, and theories about the way the world around us works. Technology includes the technological design process and the body of knowledge related to the study of tools and the effect of technology on society. Science and technology merge in the pursuit of knowledge and solutions to problems that require the application of scientific understanding and product design. Solving technological problems demands scientific knowledge while modern technologies make it possible to discover new scientific knowledge. In a world shaped by science and technology, it is important for students to learn how science and technology connect with the demands of society and the knowledge of all content areas. It is equally important that students are provided with learning experiences that integrate tools, knowledge, and processes of science and technology. The Science and Technology Standards outline the essential understandings of these disciplines. Standard A describes four themes that serve as a broad scaffold for understanding and organizing student understanding of the content and processes of science and technology. Standard B describes the processes of scientific inquiry and technological design. As a...

They then drew a grid of latitude and I-4I-5longitude lines from those geographic reference points, thereby locating any point on Earth using just two numbers. geographic grid: The system of mathematically determined latitude and longitude lines used to determine the location of every place on Earth’s surface. spatial relationships: The close association of human and natural phenomena in place and their mutual interdependence and interaction. spatial perspective: The geographic approach that places location at the center of research, analysis, and explanation. Modern geography is best understood as the study of how the physical and cultural attributes of the earth interact to form spatial or regional patterns Modern geography has improved our ability to explain the world by utilizing four traditional areas of study: • 1. the location of physical and cultural features and activities (spatial distributions); • 2. the relationships between people and the lands that support them; • 3. the existence of distinctive areas or regions, including analysis and explanation of how they came to be formed; and • 4. the physical characteristics of the earth, perhaps the oldest of all geographic traditions. patial tradition: A geographic perspective that emphasizes how things are organized in space, especially spatial distributions, associations, and interactions. man-land tradition: ...

...Earth's Surface (Absolute/Relative). Geographic study begins with the location of places on the earth. Places have absolute locations that pinpoint them on the earth, and relative locations that place each location in respect to other locations. Absolute location A location can be absolute (specific) as in coordinates of a map using longitude and latitude Relative location A location can be relative - examples: next door, nearby, a short drive, down the road a ways. Or, it can be in the same general location as another location - example: next to the post office. Place: What's it like there? Physical and Human Characteristics. Place have physical and human characteristics that make them what they are. Geography emphasizes the understanding of both of these factors and their integration together. Physical characteristics natural environment ( soil, water & climate) human characteristics man-made environment Human/Environment Interactions: Shaping the Landscape. The landscape of the earth is no longer a purely physical feature. Human have impact every area of the earth, but in varying ways.

...The relationship between the earth and the sun With a radius 110 times that of Earth and a mass 330,000 times greater, the sun reigns as the center of the solar system. The gravitational pull of the fierce, stormy ball of gas holds earth orbit, and its emissions power the Earth-atmosphere systems on which our lives depend. As the source of almost all the energy in our world, it holds the key to many of our questions about Earth and sky. Everybody is wondering about the environmental changes that take place throughout the year and from place to place over Earth’s surface. In the late years, people wondered why it got much warmer during summer than in winter and why some days were long whereas those in the other seasons were much shorter. These questions and many like them are probably as old as the earliest human thoughts, and the answers to them help to provide the understanding of the physical geography of the world. Physical geographers’ concerns take them beyond planet Earth to a consideration of the sun and Earth’s position in the solar system. Geographers examine the relationship between the sun and Earth to explain such earthly phenomena as the alternating periods of light and dark that is referred to as day and night. Other relationships between the Earth and sun also help to explain seasonal variations in climate. Although the universe and solar system are not strictly within the province of physical geography, an acquaintance with each can be helpful...

The major events discussed in this paper are the physical formation of the Earth, the Glacial Epoch, and initial oxygenation of the planet. Then it delves into Earth’s own adaptive mechanisms and its interaction with organisms that inhabit on this planet by considering factors that make life a geologic force as life and rocks developed a mutual relationship. Finally, it assesses information on Earth’s coevolutionary connection with lives on it and evaluates life and the Anthropocene Epoch. It also addresses difference...

...Task 1 In ancient civilizations it was believed that the Earth was the center of the Universe (Geocentric model). This was the accepted belief at the time. Many philosophers and scientists wrote works based on the Geocentric model. The understanding that the Earth being the center of the universe began to change as scientists (Copernicus, Galileo and Kepler) researched, used mathematics and physics. The findings of there work led to the belief that the Sun was the center of the Universe (Heliocentric model). Copernicus used mathematics (On the Revolutions of the Celestial Spheres) to form the Heliocentric model of the universe. Galileo used physics (Dialogue Concerning the Two Chief World Systems) to support Copernicus’ Heliocentric theory. Kepler mathematics (laws of planetary motion) and his expertise in optics (inventing an improved version of the refracting telescope (Keplerian Telescope) and gave credit to Galileo for his telescopic discoveries) to support the Heliocentric model. The Heliocentric model was accepted as the structure of the Solar System because of the work of these ancient scientists and the work of those that came after them. In the mid-to-late 20th century supremacy in space exploration between the Soviet Union and United States began. This is now known as the “Space Race”. During this tense time known as the “Cold War” both the Soviet Union and the United States felt that being first in space exploration was necessary for national security and...
