  1. Our Solar System An Inventory of the Solar System FREE-WRITE ! 2 minutes: Everything you know (can remember) about the solar system

  2. Ancient Greek Astronomers’ Solar System consisted of….. • 1 Moon • Stars • 5 planets: _______, ________, _________, _______, _______ • _______: long wispy strands of light that were visible for weeks and slowly faded • ________: shooting stars, bright streaks of light that shoot across the night sky. Mercury Venus Mars Jupiter Saturn Comets Meteors

  3. 17th Century Solar System • Galileo used a telescope to discover: ___________________ Moons around Jupiter, craters on the moon, phases of Venus

  4. 19th Century discoveries in the Solar System added….. • Saturn's’ Rings • The planets Uranus & Neptune • Minor planets called dwarfs • The Asteroid Belt between Mars and Jupiter

  5. 20th Century discoveries in the Solar System added:….. • Kuiper Belt beyond Neptune • Non-optical “seeing” using radio and infrared waves • Space flight: manned space craft and un-manned space probes Hubble Telescope

  6. So….Let’s Take An Inventory • Our solar system is centered around a single star; the Sun. • Planets, in order of distance from the Sun: • M_______, V_____, E____, M___, J______, S______, U______, N______ • My Very Exceptional Mother Just Served Us Nachos

  7. Let’s Take An Inventory 146 • Some of the planets have moons, totaling _______at last count. • Currently scientists have observed more than 500,000 asteroids. located in an Asteroid belt between _____ and ___________. • They are debris from the formation of the solar system. ( or a broken planet???) • Kuiper Belt: a region beyond Neptune where icy bodies orbit

  8. Overall Layout of the Solar System • Orbits of all planets are ellipses • (not perfectly round – slightly oval) • They are not evenly spaced • distance from the sun • They allorbit counter clockwise • They orbit on the same flat orbital plane (except Mercury tilts 7°)

  9. Overall Size of the Solar System • It’s IMMENSE! HUGE! • _________ AU across • 1 AU is the distance from the Earth to the Sun or 93,000,000 miles • So… (that’s ______________ miles) 80

  10. Size and Scale of our Solar system http://www.exploratorium.edu/ronh/solar_system/ http://www.classzone.com/books/earth_science/terc/content/visualizations/es2701/es2701page01.cfm http://joshworth.com/dev/pixelspace/pixelspace_solarsystem.html Group 1: Select various size balls and/or beads, to represent the relative size of each planet. Using the chart page 706 determine the diameters and distances and make a comparison for each planet; Ex. If Mercury was a marble, then the earth would be a_____________ . Group 2. Given a roll of register tape, make a scale that shows the distances of the planets form the sun. Label the scale and draw the planets on the paper tape. Group 3: Use a road map of the U.S. or Illinois or World map to relate the distances of the planets from the sun to miles on the land. Select a location for the Sun and determine how many miles each planet would be from the sun’s location. Label it. Group 4: Using a long hallway in the school and the lab activity on page 582-3, locations of each planet from the sun. Print out a picture with a label and brief description for each planet. Tape them in the appropriate location in the hallway. Group 5: Use a football field or a baseball diamond as a scale and place the planets the appropriate yard lines that correspond to their distance from the Sun.

  11. Solar System Model Scale • Select one of the methods to show the solar system. • 2.Look-up the distances in AU’s using the Astronomy book 9Appendix-5) or internet. • 3. Select a scale: • Millimeters, centimeters, inches, meters, yards, feet, miles, kilometers. • 4. Fill-in the data table. Start with the Earth as 1 AU and calculate the other planets from there. • 5. Include the Asteroid Belt and the Kuiper Belt.
