Solar System Data Inv. 1-1

  1. 1. Solar System Investigation 1; Part 1
  2. 2. Solar System Definition <ul><li>What is the Solar System ? </li></ul><ul><ul><li>Solar refers to Sol, another name for our Sun . </li></ul></ul><ul><ul><li>System is a set of objects working together </li></ul></ul><ul><li>Solar System = our Sun and a set of other objects working together in some way. </li></ul>
  3. 3. How Does the Solar System Work? <ul><li>Set of Picture Cards </li></ul><ul><ul><li>Spread out in front of you Picture-side up </li></ul></ul><ul><ul><li>Look at front of card only </li></ul></ul><ul><li>Put cards into groups by similar characteristics </li></ul><ul><ul><li>Use just what you observe in images, not prior knowledge* </li></ul></ul><ul><li>How did you sort your cards? </li></ul>
  4. 4. Card Data <ul><li>Type </li></ul><ul><ul><li>Planet, dwarf planet, star, comet, asteroid, or satellite </li></ul></ul><ul><li>Distance from Sun or other object </li></ul><ul><ul><li>Except for Sun, all orbit the Sun or other object </li></ul></ul><ul><li>Orbit period </li></ul><ul><ul><li>How long does it take to orbit the Sun in Earth days or years </li></ul></ul><ul><li>Maximum/Minimum surface temperatures </li></ul><ul><ul><li>Highest & lowest temperature recorded on surface </li></ul></ul><ul><li>Composition </li></ul><ul><ul><li>Solid, liquid, gas </li></ul></ul>
  5. 5. Orbit <ul><li>Revolving or moving in a path around another object. </li></ul><ul><li>Challenge: </li></ul><ul><ul><li>Find all the planet cards and Sun card. </li></ul></ul><ul><ul><li>Use “Distance from…” information on cards to arrange planets in order, starting with the Sun. </li></ul></ul>
  6. 6. Solar System <ul><li>Sun and eight planets in order describe the solar system </li></ul><ul><li>Other objects in solar system </li></ul><ul><ul><li>Use information on cards to incorporate other objects into solar system* </li></ul></ul>
  7. 7. Solar System Data Sheet <ul><li>Complete notebook sheet - start by filling out table on left side of sheet. </li></ul><ul><li>Planet cards </li></ul><ul><ul><li>Separate planets into classes based on composition* </li></ul></ul><ul><ul><li>How did you use composition to sort planets? </li></ul></ul><ul><ul><ul><li>Rock planets </li></ul></ul></ul><ul><ul><ul><li>Gas planets </li></ul></ul></ul><ul><ul><ul><li>Ice and rock dwarf planet </li></ul></ul></ul>
  8. 8. Composition <ul><li>What do you notice about the sizes of the planets you have put in your groups? </li></ul><ul><li>What do you notice about the distance from the Sun for the planets in your groups? </li></ul><ul><li>Terrestrial Planets </li></ul><ul><ul><li>Four rocky planets closest to the Sun </li></ul></ul><ul><ul><li>Terrestrial means “land”, rocky composition </li></ul></ul><ul><li>Gas Giants </li></ul><ul><ul><li>Beyond the asteroid belt </li></ul></ul><ul><ul><li>Why “Gas Giant” name? </li></ul></ul>
  9. 9. Pluto <ul><li>Dwarf Planet </li></ul><ul><ul><li>Located in Kuiper Belt </li></ul></ul><ul><ul><ul><li>Area filled with “dirty ice” objects, made of frozen dust, water, and gas </li></ul></ul></ul><ul><ul><ul><li>Some objects are planet size </li></ul></ul></ul><ul><li>Pluto </li></ul><ul><ul><li>Rock-and-ice dwarf planet or Kuiper object </li></ul></ul>
  10. 10. Vocabulary <ul><li>The Sun </li></ul><ul><ul><li>An average star at the center of the solar system around which all other solar-system bodies revolve. </li></ul></ul><ul><li>Solar System </li></ul><ul><ul><li>The Sun and all the bodies that orbit it, including the planets and their moons, the asteroids, and the comets. </li></ul></ul>
  11. 11. <ul><li>Orbit </li></ul><ul><ul><li>The path an object takes around another object; for example, Earth has an orbit around the Sun. </li></ul></ul><ul><li>Planet </li></ul><ul><ul><li>A large natural object that orbits around a star, such as the Sun. </li></ul></ul><ul><li>Asteroid </li></ul><ul><ul><li>A rocky object, which can be a few hundred meters to several hundred kilometers wide, that orbits the Sun. </li></ul></ul>
  12. 12. <ul><li>Comet </li></ul><ul><ul><li>A small body of ice and dust that orbits the Sun in a large oval path. </li></ul></ul>
  13. 13. Content <ul><li>What is the Sun? </li></ul><ul><ul><li>Average-sized star; mostly hydrogen (72%) and helium (26%); other solar system bodies revolve around it </li></ul></ul><ul><li>What is the solar system? </li></ul><ul><ul><li>Sun and all the bodies that orbit it, including planets and their moons, asteroids, and comets </li></ul></ul><ul><li>Your questions? </li></ul>
