  1. Falcon Focus • 1. Place the following in the correct order largest to smallest: stars, galaxies, universe, solar system, and planets • 2. Name the Planets in order. • Essential Questions: What are the differences between Inner and Outer Planets?

  2. Our Solar System Standard 8.E.4 The student will demonstrate an understanding of the universe and the predictable patterns caused by Earth’s movement in the solar system.

  3. Performance Indicator • 8.E.4B.1 Obtain and communicate information to model and compare the characteristics and movements of objects in the solar system (including planets, moons, asteroids, comets, and meteors).

  4. What does the Solar System includes? • The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids (asteroid belt), minor planets, and dust and gas.

  5. What is a planet: a celestial body moving in an elliptical orbit around a star

  6. Planets • Planetsmay have a terrestrial (earthy) or rocky surface or a gaseous surface. • Gaseous planets are considerably larger than terrestrial planets. • Planets may have rings.

  7. Planets • Movement of planets is based on revolution around the Sun and rotation on the planet’s axis.

  8. Name the Planets in order starting from the sun. • The eight planets that orbit the sun are (in order from the sun): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

  9. What is the acronym for remembering the planets in order? • "My Very Excellent Mother Just Sent Us Nachos • My Very Eager Mother Just Served Us Nachos

  10. The Breakdown between Inner & Outer Planets

  11. Inner planets: • Mercury, Venus, Earth, and Mars. • Closer to the Sun (Hotter) • Smaller • few or no moons. • Rocky planets/terrestrial planets • moves faster because the gravitational attraction is greater. • Has no rings

  12. Outer planets: • Jupiter, Saturn, Uranus, and Neptune • Huge • Has Rings • many moons • Gaseous Planets • Farther away from the Sun/ colder planets. • Moves Slower

  13. How Old Would you be on different Planets?

  14. Each planet __revolve____ around the Sun and __rotate___ on it’s axis. • Venus is the hottest planet even though Mercury is the closest planet to the Sun. The reason that Venus is hotter than Mercury is because it has an atmosphere made up of carbon dioxide; it also has clouds of acid inside its atmosphere. This is called the greenhouse effect.

  15. WHAT IS A MOON? • A rocky body covered with craters that • orbit around a PLANET.

  16. MOONS • Moons are studied in relation to the planet they orbit. Not all planets have moons. •   Most are rocky bodies covered with craters, but some have unique characteristics. •   Movement of moons is based on revolution around their planets and rotation on their axis.

  17. MOONS • Planet with the MOST moons: ___JUPITER______(63) • Planets with the LEAST moons: _MERCURY and VENUS. 0 moons

  18. PHASES OF THE MOON • PHASES OF THE MOON IN ORDER: NEW MOON, WAXING CRESCENT, FIRST QUARTER, WAXING GIBBOUS, FULL MOON, WANING GIBBOUS, LAST (THIRD) QUARTER, WANING CRESCENT.

  19. WHAT IS AN ASTEROID? • What is an asteroid? __ROCKY______bodies that orbit in the ___SUN________.

  20. Where is the Asteroid belt located? • Asteroids •   Most asteroids are rocky bodies that orbit in a region in the solar system known as the Asteroid Belt between Mars and Jupiter. • 

  21. SIZE & MOVEMENT •  They vary in size and shape. •   Movement is based on their revolution around the Sun.

  22. Asteroids

  23. Why do scientists monitor their positions? •   Some asteroids outside the asteroid belt have orbits that cross Earth’s orbit, which require scientists to monitor their positions.

  24. COMETS • IS KNOWN AS THE DIRTY SNOWBALL

  25. Comet Parts • Comets have a main body or head (ice, methane and ammonia and dust) and a tail that emerges as the comet gets closer to the Sun during its orbit.

  26. The Tail happens when the comet gets closer to the sun during it’s orbit and the head begins to melt & stream behind it .

  27. The effects of the solar windsresult in the tail always points away from the Sun. •   Comets have long, narrow, elliptical orbits that cause them to cross paths with other objects in the solar • system.

  28. Location • Most come from regions far beyond Neptune in the • * Oort___ Cloud or Kuiper Belt

  29. Meteoroids • Meteoroid: chunks of rock that move around within the solar system • Prior to entering the atmosphere the chunks of rock move about within the solar system and are known as meteoroids.

  30. METEROIDS

  31. Meteor vs. Meteorites METEOR METEORITE

  32. METEOR • Meteors are chunks of rock that burn upon entering a planet’s atmosphere. • They are also called shooting stars.

  33. METEOR

  34. METEOR SHOWER a number of meteors that appear to radiate from one point in the sky at a particular date each year, due to the earth's regularly passing through a field of particles at that position in its orbit.

  35. METEORITE

  36. 8-4.6 Explain how gravitational forces are influenced by mass and distance.

  37. Gravitational Force • The force of gravity is a pull between all objects in the universe. This force is influenced by the mass of the objects and the distance between them.

  38. A more massive object has the greater pull on the less massive objects; the Sun being most massive object in the solar system has the greatest pull on objects, like planets, in the solar system. • The closer the distance between objects the greater the pull; the Moon has a greater effect on Earth’s tides than the Sun because it is closer to Earth.

  39. These two factors of gravitational force have numerous applications on motions of celestial bodies, for example the gravitational pull between the Sun and the planets and between Earth and its Moon cause distinct motions between and among these bodies (8-4.7).

  40. 8-4.8 Explain the difference between mass and weight by using the concept of gravitational force.

  41. The concept of gravitational force can be used to explain the difference between mass and weight.

  42. Mass • Massis the amount of matter in an object; it does not depend on forces acting on it. • Mass is the sameno matter where the object is located as long as the object does not gain or lose any of its matter. • An object that has mass can be pulled on bygravitational force. • Mass is measured on a balance.

  43. Weight • Weightis a measure of the pull of gravity on an object. • Weight is related to mass but they are not the same. • Weight on Earth is based on the pull of gravity toward the center of Earth. • Weight can change on Earth since the pull of gravity is not the same everywhere.

  44. Weight • Weight can change if an object is located on another object in space, for example, the Moon or Mars. • The mass of that larger object determines the pull of gravity and therefore the weight of the object.
