AGENDAOBJECTIVE  Do Now  Big Idea Vocabulary  Homework : Fieldtrip sheet due Friday  Students will… Practice big picture vocabulary Begin to develop an understanding of major astronomy concepts

 Fold your paper into fourths  Draw divisions on the paper  Write the Big Picture Words in each section Astronomy Rotation Revolution Planet Star Solar System Moon Phases of the Moon

 Astronomy is the study of moons, planets, stars, nebulae, and galaxies, and the physics, chemistry, mathematics, and evolution of objects, that begin outside of the atmosphere of Earth.  It also includes supernovae explosions, gamma ray bursts, and cosmic background radiation.

 Astronomy is one of the oldest sciences.  Prehistoric cultures left behind astronomical artifacts that proved they performed observations of the night sky.  However, the invention of the telescope was required before astronomy was able to develop into a modern science.

 During the 20th century, the field of professional astronomy split into two branches. One branch focuses on observations, the other focuses on the physics of the stars.  Amateur astronomers, people who use astronomy as a hobby, have made important discoveries.

 Earth's rotation is the rotation of the Earth around its own axis.  The Earth rotates from the west towards the east.  If you look at the earth from the North Star or Polaris, the Earth turns counter-clockwise.

 The North Pole is different from the magnetic North Pole.  The South Pole is the other point where the Earth's axis of rotation intersects its surface, in Antarctica.  The Earth rotates once in about 24 hours.

 In astronomy, revolution is the orbit of the Earth around the Sun.  A complete revolution of the earth around the Sun occurs every 365 days.  This motion causes the season’s summer, fall, winter, and spring.

 Causes the seasons  Lasts 365 days  Earths orbit around the sun

 Do Now: Define Astronomy: Define Rotation: Define Revolution:

 A planet is an astronomical object orbiting a star and is big enough to have its own gravity.  The term planet is ancient, with ties to history, science, mythology, and religion.  The planets were originally seen by many early cultures as divine, or as Gods.

 As scientific knowledge advanced, human perception of the planets changed.  In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System.  This definition has been both praised and criticized and remains disputed by some scientists because it excludes many objects of planetary mass based on where or what they orbit.

 Eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition.  Planets are divided into two main types: large, low-density gas giants and smaller, rocky terrestrials.

 Object that orbits a star  Big enough to have its own gravity  As knowledge of planets changed, we chose to have only 8 planets

 Round object made of gas or rock  Big enough to have its own gravity  Orbits the sun  8 planets in our solar system

 A star is a huge, luminous sphere of gas held together by its own gravity.  The nearest star to Earth is the Sun, which is the source of most of our planet's energy.  Some other stars are visible from Earth during the night.

 Historically, the most prominent stars were grouped into constellations.  Constellations are groups of stars that appear to form a pattern in the night sky.  The biggest stars were given names.  Stars have lives that begin in a collapse of gas called a nebula and end in an explosion called a supernova

 VZMT1z8 VZMT1z8

 The sun is a star  Stars are born nebula and die in a supernova  Part of a galaxy  Fights against gravity to survive  Made of hydrogen (H) and helium (He)

 Stars are made of Helium (He) and Hydrogen (H)  There are over 40 billion stars in our galaxy  Stars are born in nebula and die in a supernova

 The Solar System is made of the sun, eight planets, and all objects that orbit the sun.  Our solar system was formed 4.6 billion years ago.  There is an inner solar system that includes Mercury, Venus, Earth, and Mars.  There is also an outer solar system Jupiter, Saturn, Uranus, and Neptune.  The asteroid belt separates the inner and outer solar systems.

 Formed 4.6 billion years ago  Divided into the inner and outer solar system  8 planets  Asteroid belt

 The Moon is the only natural satellite of the Earth and the fifth largest moon in the Solar System.  The Moon is in synchronous rotation with Earth, always showing the same face.  It is the brightest object in the sky after the Sun, although its surface is actually dark.  Its prominence in the sky and its regular cycle of phases have, since ancient times, made the Moon an important cultural influence on language, calendars, art and mythology

. The Moon's gravitational influence produces the ocean tides.  The Moon is thought to have formed nearly 4.5 billion years ago, not long after the Earth.  The Moon is the only celestial body other than Earth on which humans have set foot.  The Moon remains, under the Outer Space Treaty, free to all nations to explore for peaceful purposes.

 5 th largest moon in our SS  Formed 4.5 billion years ago  Influences tides  There were active volcanoes on the moon  Craters from volcanoes and impacts  Our only natural satellite  Rotates at the same speed as the Earth

 Formed 4.5 billion years ago  Brightest thing in the sky besides the sun  5 th largest moon in the SS  Rotates with the Earth

 Only natural satellite of the Earth  Our moon is the 5 th largest in the SS  Created 4.5 billion years ago  Anyone can land on the moon

 Phase of the moon refers to the shape of the sunlit portion of the Moon as seen by an observer, usually on Earth.  The lunar phases change cyclically as the Moon orbits the Earth.  The half of the moon surface facing the Sun is always sunlit, but the portion of this illuminated hemisphere that is visible to an observer on Earth can vary from about 100% (full moon) to 0% (new moon).

 All parts of the Moon see around days of sunlight followed by days of "night.”  The four major phases of the moon are called the new moon, first quarter moon, full moon and last quarter moon.

 TWTZlks TWTZlks

 All parts of the moon see days of “day” and “night”  Last quarter moon, first quarter moon, new moon, full moon

 New moon, first quarter moon, full moon, last quarter moon  Change as the moon orbits the Earth  The moon sees 15 days “day” and 15 days “night”

 Due to WKCE testing students only saw Mrs. Burke two days this week. Please see WKCE testing Power Point for alternative activities students worked on with other teachers.
