Transcript

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