A day is defined scientifically as the time it takes Earth to complete one rotation. There are 7 days in a week based on the 7 celestial objects (Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn) visible in ancient times. Each day of the week is named after these objects. The word "month" comes from "moon" as it is based on the moon's revolution around Earth, which takes approximately 29 days. A year is the time it takes Earth to revolve around the Sun, which is 365.2422 days. We measure it as 365 days and add an extra day to February every 4 years to account for the extra .2422 days, calling it a leap

What time is it?
The document discusses the Earth's rotation and revolution and how it influences time measurements. It takes the Earth approximately 24 hours to complete one rotation on its axis. The days of the week are named after objects visible in the sky, with Sunday through Friday named after the sun, moon, Mars, Mercury, Jupiter, and Venus. Months are based on the moon's cycle around Earth, taking approximately 28 days, while years represent the time for Earth to complete one revolution around the sun, which takes 365.2422 days.
Why do we measure time the way that we do
Day and night are caused by the Earth's rotation on its axis over 24 hours. Weeks consist of 7 days which are associated with the sun and visible objects in the night sky. Months are based on the moon's approximately 29.5 day revolution around Earth, though months contain 30-31 days. Years measure the 365.2422 days it takes Earth to orbit the sun, requiring a leap year every four years, except for centennial years which must be divisible by 400 to be a leap year.
Chapter 10 ii
The document summarizes key aspects of plate tectonics theory including:
1) Continents were once joined together in a supercontinent called Pangaea before drifting apart to their current locations, as evidenced by matching coastlines and fossil/rock formations.
2) Seafloor spreading was discovered at mid-ocean ridges and explained how new crust is formed through magma rising at these ridges and pushing plates apart over time.
3) Earth's crust is broken into plates that move atop the mantle, interacting at plate boundaries through spreading, subduction, and transformation, causing volcanic and seismic activity.
09 25-2013-paleontology review
This document contains 20 questions from a paleontology test review game along with their answers. The questions cover various topics about relative age, the geologic time scale, fossils, extinction, uniformitarianism, the principles of superposition and original horizontality, sedimentary rocks, and major eras like the Cenozoic and Mesozoic. The answers define key terms, name major geologic eras, and explain how fossils provide evidence about past environments and climate change over time.
09 30-2013-what are
This document outlines a concept attainment lesson where students are given examples and non-examples of an unknown concept and are tasked with generating a hypothesis to define the concept. Students are given three rounds of examples and non-examples that include items like soil, trees, cows, cars, and houses. They are asked to refine their tentative hypothesis with each new round. The lesson aims to have students develop a hypothesis to define the unknown concept based on analyzing the commonalities among examples and differences from non-examples.
09 23-2013-principles
The document discusses geologic principles for understanding the Earth's history. Students are asked to brainstorm how these principles are like a layer cake. The principles discussed are uniformitarianism, superposition, original horizontality, and catastrophism. For each principle, students come up with a simile comparing it to a layer cake and illustrate it. They then answer the evocative question of how the geologic principles are like a layer cake by brainstorming as a group.
Geologic time scale
The document divides Earth's geologic history into a time scale consisting of eons, eras, periods, and epochs. Major changes in lifeforms or the environment define the boundaries between these divisions. The Precambrian era spanned from Earth's formation 4.6 billion years ago until 542 million years ago and saw the emergence of early prokaryotic and then eukaryotic life. Mass extinctions, such as those at the ends of the Paleozoic and Mesozoic eras, were often caused by catastrophic asteroid impacts or climate change and marked transitions between eras.
Plate Tectonics 10.1 08 09
The document summarizes Alfred Wegener's theory of continental drift from 1912, which proposed that the continents were once joined together in a single landmass called Pangaea surrounded by a large ocean called Panthalassa. Wegener's theory was initially rejected because he could not explain what caused the continents to move. In the 1960s, the theories of sea floor spreading and paleomagnetic reversal provided evidence that the continents have moved over time, supporting continental drift.

The document provides information about stars, galaxies, constellations, and calendars. It discusses:
1) The definition of a star and how stars are classified by temperature and spectra into 7 main types from O to M stars.
2) What galaxies are, the different types (spiral, elliptical, lenticular, irregular), and examples of each type.
3) How constellations are groups of stars that appear close together and form patterns, and how they have been used to locate objects in the sky, determine directions, and entertain people through cultural stories.
What are stars
Stars are giant balls of hot gas that produce energy. Our sun is a star that is closest to Earth and provides light and heat. Scientists use telescopes and tools like spectroscopes to examine the sun and learn about its composition and energy output. Scientists describe stars based on their physical characteristics like size, brightness, temperature, and color. Stars can vary significantly in these traits.

02 lecture outline
The document discusses patterns observed in the night sky from Earth and what was historically mysterious about planetary motions. It describes how planets appear to move eastward but sometimes backwards, known as retrograde motion. The ancient Greeks could not explain this and rejected that Earth orbits the sun due to being unable to detect the parallax of distant stars with the naked eye. They concluded Earth must be stationary at the center of the universe. The document also reviews lunar phases, eclipses, and the reasons for seasons.
02 lecture outline
The document discusses patterns observed in the night sky from Earth and what was historically mysterious about planetary motions. Specifically:
1) Planets appear to normally move eastward among the stars but sometimes reverse to westward motion, known as retrograde motion. This was difficult to explain under the ancient Earth-centered model.
2) The ancient Greeks rejected the sun-centered explanation for planetary motion because they thought stellar parallax should be observable if the stars were actually very far away.
3) What appears as retrograde motion of planets is actually caused by Earth "lapping" other planets in their orbits around the sun.
Constellations
The unaided human eye can see about 6,000 stars on a clear night, with about 3,000 stars visible at any given time. However, light pollution limits the number of visible stars to a few hundred for most locations. The apparent brightness of celestial objects is measured on the magnitude scale, with 1st magnitude stars being the brightest and 6th magnitude stars being the faintest visible to the unaided eye. Constellations help organize the sky into defined regions, though the stars within a constellation may be located at different distances.

This document provides information about stars, galaxies and the universe. It begins by explaining that the volume of the sun is approximately 1,000,000 times greater than the volume of Earth. It then discusses that the universe contains matter such as gas, dust and objects that form stars, planets and other celestial bodies. Galaxies, which can be spiral, elliptical or irregular, are large groupings of stars held together by gravity. Our solar system is located in the Milky Way galaxy, approximately 100,000 light years across.
Ppt 6th earth in solar system
1. The document discusses the celestial bodies that can be seen in the night sky, including stars, planets, and other astronomical objects that orbit the Sun.
2. It explains that stars produce their own light and heat, while planets like Earth receive light from stars and have no internal light source of their own.
3. The Solar System is made up of the Sun and objects that orbit it, including 8 planets, their natural satellites like Earth's Moon, asteroids, and comets.
What is a star
1) Stars appear as points of light because they are very far away from Earth, even stars within our own galaxy like Andromeda.
2) Stars are giant balls of hot, glowing gases that produce light and energy through nuclear fusion at their cores.
3) The brightness of stars is determined by their temperature, size, and distance from Earth, with brighter stars being hotter, larger, or closer.
Our solar system
Chris shared with his brother Nick what he had learned about the Solar System in school. He discussed the different objects in the Solar System such as the Sun, eight planets, moons, asteroids and comets. Nick helped explain some of the key terms to Chris like orbit, planet, and dwarf planet. Chris was surprised to learn that Pluto is now considered a dwarf planet instead of a major planet. Nick also explained the differences between asteroids and comets to Chris. For his homework, Chris plans to write a summary of the inner and outer planets using science vocabulary, and create a labeled diagram of the Solar System.
The earth and its neighbours
The document discusses the Earth and its place in the solar system. It describes the Earth's rotation and revolution around the Sun, which causes the seasons. It also discusses other planets, stars, galaxies and satellites. The Earth formed from a ball of dust and gases and has a molten core, mantle and solid crust. Volcanic eruptions occur when gases and liquids from the core breach weaknesses in the crust.

The document discusses observations about the sky, sun, moon, stars, and planets:
1. The sun appears to go below the horizon at night but does not disappear - it is a star that gives light and heat to Earth.
2. The sun warms the Earth unevenly throughout the day, appearing low in the morning and evening and high at noon when it is hottest.
3. The moon does not produce its own light but reflects the sun's light, appearing in the night sky and sometimes during the day, with its shape changing over 28 days as it orbits Earth.
4. Stars are very distant suns that appear as patterns or constellations in the night sky, like
The earth in solar syatem
The document discusses celestial bodies in the night sky. It defines celestial bodies as any natural objects outside Earth's atmosphere, including the moon, sun, planets, asteroids, meteoroids, and stars. It provides details about the phases of the moon, including new moon nights called Amavasya. It also describes the key components of the solar system, including the sun, eight planets, asteroids, and meteoroids. It gives an overview of Earth's orbit and conditions that support life.
Our Solar System
This document provides an overview of our solar system, including the sun and objects that orbit it such as 8 planets, dwarf planets, asteroids and comets. It describes details about each planet such as their orbital periods, temperatures and number of moons. It also discusses the gas giants Jupiter and Saturn and ice giants Uranus and Neptune. The document explains that gravity is what causes the planets to orbit the sun and how it drew gases together to form the spherical planets we see today. It encourages learning more about ongoing space exploration through NASA's website and the historic Voyager 1 mission.
Time And Calendars 2009
The document discusses various units of time including days, months, years and their astronomical origins. It describes solar and sidereal time and how precession causes the constellations to change position relative to the seasons. Standard time zones were established in the late 19th century to accommodate railroad schedules. Sundials are among the earliest timekeeping devices and use shadows to indicate local apparent time. The modern Gregorian calendar improved on the Julian calendar by more accurately accounting for the tropical year.
Geologic Similes
The document discusses four geologic principles - uniformitarianism, superposition, original horizontality, and catastrophism - and compares each principle to the layers of a cake. Uniformitarianism is like a cake in that the ingredients and process of making a cake are always the same. Superposition is like a cake as the bottom layer was placed first and each subsequent layer above it is younger. Original horizontality is like cake layers in that they should be placed horizontally. Catastrophism is like a dropped cake that is suddenly ruined. The document provides additional examples comparing the principles to other everyday items like clothes piles and bicycles.
Exploration
Ancient societies like the Egyptians, Mayans, and builders of Stonehenge began exploring the night sky to develop calendars and track seasonal changes. Greeks like Aristotle and Ptolemy developed early geocentric models of the solar system, though their ideas were inaccurate. Copernicus, Brahe, Kepler, Galileo and Newton made important contributions to establishing the heliocentric model through observations, mathematics, and physics theories like gravity. Continued exploration has led to discoveries of new objects in our solar system like Uranus, Neptune, Pluto and the Kuiper Belt.

Geologic Principle Similes
The document discusses geological principles for understanding the Earth's history using the analogy of a layer cake. It explains four key principles:
1) Uniformitarianism - geological processes occurred the same way in the past as today, like how cakes are made the same way each time.
2) Superposition - the oldest sedimentary layers are on the bottom, like how cake layers are placed with the bottom being oldest.
3) Original Horizontality - sedimentary rocks form in horizontal layers, similar to cake layers being placed horizontally.
4) Catastrophism - geological change can occur suddenly, akin to a dropped cake being ruined suddenly.
Dance of the planets
The document describes the fundamental force of gravity. It explains that gravity is a weak but predictable force that helped form the universe and has a constant presence, distorting space and time and acting on all matter through mass. Gravity keeps objects like ourselves on Earth and the Earth orbiting the sun according to laws proposed by Newton and Einstein describing gravity's proportional relationship to mass and dependence on net force and inertia.
Cloud Challenge: Alto Clouds
This document discusses two types of middle-level clouds known as alto clouds: altostratus and altocumulus. Altostratus clouds are gray and blue clouds that often cover the sky and are associated with areas of storms and continuous precipitation, composed of ice and water droplets. Altocumulus clouds appear as gray, puffy masses that form in parallel waves or bands, usually occurring on warm, humid summer mornings and often indicating upcoming thunderstorms. Pictures and websites with additional information about alto clouds are also provided.

For each type of energy, it lists key pros and cons, such as coal being abundant but emitting greenhouse gases, and solar producing no waste but having high upfront costs. It also poses reflection questions to encourage deeper consideration of the topics.
09 24-2013-relative age
This document discusses methods for determining the relative age of rocks and fossils, including using the principle of superposition, where older rock layers are found below younger ones, and examining index fossils, which are fossils that lived during a short period of time that can help date the rock layer. It also mentions radiometric dating as a way to determine the absolute age of rocks and fossils by measuring the decay of radioactive isotopes. The document provides questions for students to think about the geologic column and which layers and fossils are oldest versus youngest.
09 24-2013-relative age
This document discusses methods for determining the relative age of rocks and fossils, including using the principle of superposition, where older rock layers are below younger ones, and looking at index fossils which lived during short, identifiable periods of time. It also briefly introduces the concept of absolute age dating using radiometric dating techniques, and contains exercises for students to practice determining relative age from a model geologic column by identifying the oldest and youngest layers and index fossils.
Rocks Review 2013-2014
This document provides information about classifying and identifying rocks and minerals. It includes directions for an in-class activity where students will classify rocks, label the rock cycle, and answer questions about rock and mineral formation. It also describes a review game where students answer questions as a group about topics like the three main rock types, what rocks are made of, how rocks are used, and processes involved in the rock cycle.
Minerals Review
This document contains 10 questions about minerals and answers the questions. It tests knowledge about the definitions of minerals, including that minerals must be inorganic, form repeating crystalline patterns, and can form through crystallization of magma. It also covers hardness of common minerals on the Mohs scale such as diamond, quartz and talc. The questions assess understanding of how minerals form inside the Earth and on its surface.
Where does it come from?
The things we use everyday come from minerals, animals, and plant products. Can you identify the items and their sources?
Interactive notebook 2013 2014
This document provides instructions for setting up and using an interactive science notebook (ISN) in class. The ISN is divided into two sections - the left side for notes and the right side for creative reflections. The left side contains information from the teacher, while the right side encourages drawings, diagrams and other creative responses from the student. Each unit will begin with a colorful cover page introduction. The notebook should be numbered and maintained according to the guidelines to allow the student to learn and reflect on science like a real scientist.
Comets asteroids meteors wilson 2013 with foldable
Comets are icy, dusty clumps that originate in the outer solar system. They have elliptical orbits that can bring them close to the sun, where their ice vaporizes to form a coma and tail. Asteroids are rocky remnants from the early solar system located mainly in the asteroid belt between Mars and Jupiter. Jupiter's gravity prevented an asteroid from forming into a planet. Meteoroids are small rocks and dust that become meteors as they burn up in Earth's atmosphere, or meteorites if they survive entry and hit the surface.
Climate 2013
The temperature and precipitation in different areas are determined by two main factors: the angle of sunlight received, which is affected by latitude and elevation, and atmospheric circulation patterns like ocean currents and prevailing winds, which influence how much moisture is transported to a location. Variations in factors like latitude, elevation, proximity to large bodies of water, and ocean currents and wind patterns cause places on Earth to have different temperatures and amounts of precipitation, resulting in the major climate zones of tropical, temperate, and polar.
Air masses and fronts 2013
An air mass is a large body of air with similar temperature, pressure, and humidity levels throughout. There are four main types of air masses: maritime, continental, polar, and tropical. Air masses get their properties from spending prolonged periods over certain areas, such as oceans or polar regions. When two different air masses meet, fronts are formed. The three main types of fronts are cold fronts, warm fronts, and stationary fronts.
02 13-2013-test review
The document is a quiz about the atmosphere and weather. It covers topics like the greenhouse effect, different methods of heat transfer, wind patterns, cloud formation, air pressure, and layers of the atmosphere. Questions are multiple choice or require short answers about concepts such as what absorbs UV radiation, how convection works, types of winds, and tools used to measure temperature and pressure.
