Size and Distance. From an average distance of 93 million miles (150 million kilometers), Earth is exactly one astronomical unit away from the Sun because one astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. This unit provides an easy way to quickly compare planets' distances from the Sun.

1. Earth System History Stanley Pdf 150 Instructions

Our planet probably experienced its hottest temperatures in its earliest days, when it was still colliding with other rocky debris careening around the solar system. The heat of these collisions would have kept Earth molten, with top-of-the-atmosphere temperatures upward of 3,600° Fahrenheit.Even after those first scorching millennia, however, the planet has sometimes been much warmer than it is now. One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Another “warm age” is a period geologists call the Paleocene-Eocene Thermal Maximum, which occurred about 56 million years ago.

Cartoon by Emily Greenhalgh, NOAA Climate.gov.History of hotTemperature records from thermometers and weather stations exist only for a tiny portion of our planet's 4.54-billion-year-long life. By studying indirect clues—the chemical and structural signatures of rocks, fossils, and crystals, ocean sediments, fossilized reefs, tree rings, and ice cores—however, scientists can infer past temperatures.None of that helps with the very early Earth, however. During the time known as the Hadean (yes, because it was like Hades), Earth’s collisions with other large planetesimals in our young solar system—including a Mars-sized one whose impact with Earth is thought to have created the Moon—would have melted and vaporized most rock at the surface. Because no rocks on Earth have survived from so long ago, scientists have estimated early Earth conditions based on observations of the Moon and on astronomical models. Following the collision that spawned the Moon, the planet was estimated to have been around 2,300 Kelvin (3,680°F). What the collision that spawned Earth's Moon may have looked like.

Collisions between Earth and rocky debris in the early solar system would have kept the surface molten and surface temperatures blistering. Image courtesy.Even after collisions stopped, and the planet had tens of millions of years to cool, surface temperatures were likely more than 400° Fahrenheit. From Australia, only about 150 million years younger than the Earth itself, hint that our planet may have cooled faster than scientists previously thought. Still, in its infancy, Earth would have experienced temperatures far higher than we humans could possibly survive.But suppose we exclude the violent and scorching years when Earth first formed. When else has Earth’s surface sweltered?Thawing the freezerBetween 600 and 800 million years ago—a period of time geologists call the Neoproterozoic—evidence suggests the Earth underwent an so cold that ice sheets not only capped the polar latitudes, but may have extended all the way to sea level near the equator. Reflecting ever more sunlight back into space as they expanded, the ice sheets cooled the climate and reinforced their own growth.

Obviously, the Earth didn’t remain stuck in the freezer, so how did the planet thaw?Even while ice sheets covered more and more of Earth’s surface, tectonic plates continued to drift and collide, so volcanic activity also continued. Volcanoes emit the greenhouse gas carbon dioxide. In our current, ice-age-free world, the natural weathering of silicate rock by rainfall consumes carbon dioxide over geologic time scales.

During the frigid conditions of the Neoproterozoic, rainfall became rare. With volcanoes churning out carbon dioxide and little or no rainfall to weather rocks and consume the greenhouse gas, temperatures climbed.What evidence do scientists have that all this actually happened some 700 million years ago? Some of the best evidence is ' lying directly over Neoproterozoic-age glacial deposits. Cap carbonates—layers of calcium-rich rock such as limestone—only form in warm water. Rock formation in Namibia that shows a type of rock that only forms in warm water (cap dolostone) lying directly over a type of jumbled sedimentary rock, dated to 635 million years ago, that is commonly found at the margin of glaciers (diamictite).

Image from available at SnowballEarth.org.The fact that these thick, calcium-rich rock layers sat directly on top of rock deposits left behind by retreating glaciers indicate that temperatures rose significantly near the end of the Neoproterozoic, perhaps reaching a global average higher than 90° Fahrenheit. (Today's global average is lower than 60°F.)The tropical ArcticAnother stretch of Earth history that scientists count among the planet’s warmest occurred about 55-56 million years ago.

The episode is known as the Paleocene-Eocene Thermal Maximum (PETM).Stretching from about 66-34 million years ago, the Paleocene and Eocene were the first geologic epochs following the end of the Mesozoic Era. (The Mesozoic—the age of dinosaurs—was itself an era punctuated by 'hothouse' conditions.) Geologists and paleontologists think that during much of the Paleocene and early Eocene, the poles were free of ice caps, and palm trees and crocodiles lived above the Arctic Circle.

The transition between the two epochs around 56 million years ago was marked by a rapid spike in global temperature. Around the time of the Paleocene-Eocene Thermal Maximum, much of the continental United States had a sub-tropical environment. This fossil palm is from Fossil Butte National Monument, Wyoming. Image courtesy U.S.During the PETM, the global mean temperature appears to have risen by as much as 5-8°C (9-14°F) to an average temperature as high as 73°F. (Again, today’s global average is shy of 60°F.) At roughly the same time, paleoclimate data like fossilized phytoplankton and ocean sediments record a massive release of carbon dioxide into the atmosphere, at least doubling or possibly even quadrupling the background concentrations.

This module focuses on solar energy and the variables that affect solar energy transfer. During the unit, students chart changes in the size and position of shadows as the relative position of the sun changes; they investigate temperature changes in equal amounts of water, sand, dry soil, and wet soil when the sun shines on them; and they relate the temperature differences to the properties of the materials. Students then conduct controlled experiments to test the effect of 3 variables on the collection of solar energy by solar water heaters. (The variables are the color of the solar collector, its being covered or uncovered, and its surface area.) Finally, they assemble model solar homes, looking for the most efficient way to heat them.

Throughout the unit students organize data on charts and graphs to establish relationships between variables.Solar Energy contains 4 multipart activities, requiring about 12 class sessions of 30 to 60 minutes each. The teacher's guide includes a module overview, the 4 individual activity folios, duplication masters (in English and Spanish) for student sheets, and an annotated bibliography. 4.10 Asteroid!Russell G. Event-Based Science series. Menlo Park, Calif.: Innovative Learning Publications, 1996.Program Overview The Event-Based Science series is a program for middle school students in grades 6-9. Each module tells the story of a real event—such as the 1995 outbreak of the Ebola virus in Zaire—through reprinted newspaper articles and personal interviews; sections of background information explain relevant scientific concepts.

A central task related to the module's story line leads to a final product that allows students to apply the science they have learned. For each module, a student book, teacher's guide, and videotape and/or videodisc are available.Student Edition Recommended grade level: 7-8. The threat of an asteroid hitting the earth is the event on which this study of various topics in astronomy is based. Students begin the module Asteroid! By watching television news coverage and reading newspaper articles about objects from space that have hit or just missed hitting the earth. They are told that their major task during the module will be to design, in 5-member teams, a multimedia information campaign to warn people about an asteroid that is on a collision course with the earth. The module's 7 activities provide students with the background information and skills they need for this task.Among the activities, for example, students work with sand and small objects to investigate how an asteroid's speed and size affect the diameter of an impact crater.

They create a time line to see if there is a relationship between mass extinctions and asteroid impacts. They also design and illustrate a scale drawing of the inner planets showing the path of an approaching asteroid, and they construct an 'asteroid-smasher' model rocket capable of hitting a target 1 foot in diameter at a distance of at least 30 feet. Students also calculate the time it would take a free-falling object to reach the earth's surface.The module provides short narratives about astronomical topics, such as the origin of the moon, the solar system, and comets. It includes copies of actual newspaper articles, explanatory graphics, and profiles of professionals—such as public relations managers, planetary scientists, paleontologists, and physicists—who might be involved in a public relations campaign about asteroids.

Other information that students need to complete the task must be obtained from encyclopedias, textbooks, films, magazines, and other sources they can find. The unit culminates with the presentation of team multimedia projects.Teacher's Edition The teacher's guide provides brief overview information on the module's structure and activities. 4.11 Convection: A Current Event.Reprinted with revisions.

The series is constructed around 7 major themes: (1) systems and interactions, (2) scale and structure, (3) stability, (4) energy, (5) evolution, (6) patterns of change, and (7) models. The subject of each unit—for example, earth and beyond—is presented from the perspective of one or more of these themes. One theme is designated as the 'major theme' for a unit, and any others are treated as 'related themes.' For each unit, a wide range of materials, including some optional components, is available for students and teachers.Student Edition Recommended grade level: 7-8. Earth and Beyond contains 5 lessons that introduce students to the planet earth, its neighbors in the solar system, the galaxy, and the universe.

The organizing themes for the unit are scale and structure (major theme), systems and interactions (related theme), and models (related theme).Each of the 5 lessons in the unit typically requires 5 days to complete. During the unit, students first examine the earth as part of the sun-moon-earth system and learn that the relative positions of these 3. Astronomical objects produce various phenomena—such as seasons, tides, and phases of the moon. Students are introduced to the characteristics of the different planets in the solar system.

They find out about star formation and the relationship of a star's color to its evolution. They learn about galaxies, the Big Bang theory of the origin of the universe, and different types of earth- and space-based space exploration.Sample activities include using a thermometer, foam balls, and black paper to investigate why the earth experiences seasons; constructing a scale model of the solar system; and making and experimenting with a simple spectroscope.

The unit's 5 'explore activities,' which are lab activities, each take a class period to complete. Students use activity logs to record ideas, observations, and results.Special unit features include curriculum links to language arts, literature, mathematics, music, and art; information about science careers; and narrative sections highlighting science, technology, and society connections.Teacher's Planning Guide The teacher's planning guide, a spiral-bound, wraparound edition, provides information and strategies for teaching the 5 lessons in the student edition. Each lesson is introduced by a 4-page section that offers background information, a lesson-planning guide, and assessment options. Marginal notes on the lesson pages provide discussion ideas, tips on meeting individual needs, suggestions for addressing misconceptions, assessment ideas, and curriculum connections.Program Resources and Support Materials A wide range of materials, including some optional components, is available.

4.13 Earth, Moon, and Stars.Reprinted with revisions. Great Explorations in Math and Science (GEMS) series. Berkeley, Calif.: Lawrence Hall of Science, 1994.Program Overview The Great Explorations in Math and Science (GEMS) series includes more than 50 teacher's guides and handbooks for preschool through grade 10.

About 35 of these are appropriate for middle school. The series also includes several assembly presenter's guides and exhibit guides. New guides and handbooks continue to be developed, and current titles are revised frequently. The series is designed to teach key science and mathematics concepts through activity-based learning. The time needed to complete GEMS units varies from about 2 to 10 class sessions.Teacher's Guide Recommended grade level: 5-8. In Earth, Moon, and Stars, students investigate ancient models of the universe, the earth's shape, gravity, the moon and its phases, star clocks, and star maps.

They compare 4 ancient models of the earth to learn how each one explained common events seen daily in the sky, then they invent their own 'ancient models' of the world. They use a questionnaire to launch a discussion about the shape of the earth and about gravity. Students observe the phases of the moon for a month; use a model to explain the moon's monthly cycle of phases and eclipses; make and use star clocks; and learn how to find constellations in the night sky by reading star maps. All of the activities can be done in the classroom or outdoors during the daytime, with a few evening homework assignments.The 6 activities in Earth, Moon, and Stars require 6 sessions of 40 to 45 minutes each, 4 sessions of 20 to 30 minutes each, and 6 sessions of 15 minutes each.

The lessons each include a materials list, preparation. Steps, and directions for activities and discussion. 4.14 Earth, Moon, and Sun.John G. Radzilowicz and Jan M.

Delta Science Module (DSM) series. Hudson, N.H.: Delta Education, 1994.Program Overview The Delta Science Module (DSM) series has 51 life, physical, and earth science units for grades K-8 that emphasize science concepts, science content, and process skills. The series includes 12 modules for grades 5-6 and 8 modules for grades 6-8. Each requires about 3 to 4 weeks to complete and includes a teacher's guide and materials for a class of 32 students.Teacher's Guide Recommended grade level: 6-8. Earth, Moon, and Sun helps students investigate the properties of and relationships among the earth, moon, and sun. During the unit, students gather and analyze data on the sun and moon through observation.

They make 2- and 3-dimensional scale models of the solar system and the earth-moon system; and they create a real-time model of the earth by rectifying a globe, then use the globe to investigate phenomena such as day, night, sunrise, and sunset.In other activities, students construct a large, simple horizontal sundial in which they are the gnomon; they model the rotation and revolution of the earth; and they learn how the tilt of the earth is responsible for seasonal changes. Students also model the motions of the moon in relation to the earth and sun; they model solar and lunar eclipses; and they model the positions of the earth, moon, and sun to gain an understanding of the causes and varieties of tides on earth. They also perform some simple techniques of celestial navigation.The 13 activities in Earth, Moon, and Sun are organized to be completed sequentially over 3 to 4 weeks. Each activity takes between 30 and 50 minutes each and can be done by students working individually or in groups.A 'connections' feature at the end of each activity provides suggestions for extending or applying the concepts in the activity.

Discussion or activity topics include technology, society, science and careers, language arts, mathematics, the arts, social studies, and health. Follow-up activities that students can do at home or out of the classroom are also provided. For example, a 'science and language arts' connection suggests that students read at least the first 6 chapters of Samuel Clemens's A Connecticut Yankee in King Arthur's Court and describe how the nine.
