Earth Science Rocks! Warm up March 29 Question: Collaborating with your neighbor, put these words in order from smallest to largest: Galaxy, Planet, Solar System, Moon, Universe Earth Science Rocks! MYP Unit Question: What’s out there? Area of Interaction: Human Ingenuity Learner Profile: Risk taker Standard: Explore current scientific views of the universe and how those views evolved. Earth Science Rocks! Opening: Solar System Song Work Session: Complete Solar System Foldable Closing: What’s the weather like on Mars? Learning Standard: We are learning about our Solar System because we need to know about our neighbors. The Planets in our solar system What is an AU? An astronomical unit (AU) is the average distance of the Earth from the sun. 1 AU = 93 million miles! INNER PLANETS (Terrestrial Planets) MERCURY • SURFACE: Rock & Metal • ATMOSPHERE: Very thin atmosphere (nitrogen, oxygen) • TEMPERATURE: -297° F - 870° F • LIQUID WATER?

At one time…not now • MASS: 0.11 Earths • DISTANCE FROM SUN: 1.52 AU • REVOLUTION PERIOD: 1.9 years • MOONS: 2 • RINGS: 0 SUMMARIZE! WHAT FEATURES DO THE TERRESTRIAL PLANETS HAVE IN COMMON? QUESTION… WHICH OF THE TERRESTRIAL PLANETS BESIDE EARTH MAY BE ABLE TO SUPPORT LIFE? outer PLANETS (jovian gas giant Planets) jupiter • SURFACE: Frozen and liquid hydrogen, helium • ATMOSPHERE: Extremely thick hydrogen and helium • TEMPERATURE: -234°F average • LIQUID WATER? No • MASS: 318 Earths • DISTANCE FROM SUN: 5.20 AU • REVOLUTION PERIOD: 11.8 years • MOONS: 63 • RINGS: 3 very faint rings saturn • SURFACE: Frozen and liquid hydrogen, helium • ATMOSPHERE: Extremely thick hydrogen and helium • TEMPERATURE: -288°F average • LIQUID WATER? No • MASS: 95.2 Earths • DISTANCE FROM SUN: 9.52 AU • REVOLUTION PERIOD: 29.5 years • MOONS: 60 • RINGS: Thousands of rings made of ice and particles ranging from dust to the size of a house uranus • SURFACE: Frozen and liquid hydrogen, helium • ATMOSPHERE: Extremely thick hydrogen and helium • TEMPERATURE: -357°F average • LIQUID WATER? No • MASS: 14.4 Earths • DISTANCE FROM SUN: 19.2 AU • REVOLUTION PERIOD: 84 years • MOONS: 27 • RINGS: About 13 SUMMARIZE! What is the relationship between a planet’s distance from the sun and its revolution period? neptune • SURFACE: Frozen and liquid hydrogen, helium, and methane • ATMOSPHERE: Extremely thick hydrogen and helium • TEMPERATURE: -353°F average • LIQUID WATER? No • MASS: 17 Earths • DISTANCE FROM SUN: 30 AU • REVOLUTION PERIOD: 165 years • MOONS: 13 • RINGS: 9 faint rings SUMMARIZE! What features do the gas giants have in common? Pluto (dwarfplanet) • SURFACE: Ice and rock • ATMOSPHERE: Sort of has one… • TEMPERATURE: -387°F average • LIQUID WATER? No • MASS: 0.002 Earths • DISTANCE FROM SUN: 39.5 AU • REVOLUTION PERIOD: 248 years • MOONS: 3 (Charon is an icy companion moon) • RINGS: None When Pluto is closer to the sun in its orbit, the warmth from the sun heats up the frozen ices of nitrogen, methane and carbon monoxide on Pluto's surface. These ices vaporize and form a temporary atmosphere. When Pluto moves farther from the sun, the atmosphere freezes and falls back onto Pluto's surface. ~NASA Organization
