PPT-Formation of Earth, Moon, and planets (cont’d)

Part 1 Origin of the elements Part 2 Geochronometry Age of Earth Formation of Earth and Moon Differentiation of core and mantle Isotope tracing sequence of events What have we learned so far. The BIG Idea. Students will understand that the appearance of the moon changes in a predictable cycle as it orbits Earth and as Earth rotates on its axis.. Objective 1:. Explain patterns of changes in the appearance of the moon as it orbits Earth. . Phases are different views of the Moon’s sunlit half. The Lunar phases are the lit & unlit portions of the moon you see from Earth.. Light from the sun reflected by the Moon’s surface. The Moon’s position in its monthly orbit determines how it appears from Earth.. Formation of the Solar System. Formation of the Solar System. Scientists claim that 4.5 billion years ago there was just a featureless cloud of . gas..mostly. hydrogen and some helium with a little carbon and iron. ASTR 101. Prof. Dave Hanes. The . Moon. ’. s .

Totality lasts only a few minutes!. Geochronometry. Isotope tracing. History . of “primordial” . Pb. Meteorite samples . Chondrite. – a primitive, undifferentiated meteorite. CI refers to a particular class of carbonaceous . chondrite. E.ST.05.22: Explain the phases of the moon. . Write down everything in yellow. . CO: I can explain why the moon appears to go through eight different phases in sky. . You are about to create a R.A.N. chart in your science notebook to discuss what we already know about tides and make predictions about what we might learn. . By Jason Janczak. SIZE OF THE EARTH, MOON, AND SUN. The Earth’s radius is 3959 miles. The Moon’s radius is 1079 miles . The Sun’s radius is 432,474 miles. Fun facts: The Earth is about 4 times the size of the . 1. st. period. Solar Eclipse. Moon comes in between the Earth and Sun; annually (1x a year)- blocks sun. Can see the top layer of the sun (corona). Penumbra + Umbra (2 shadows). Most eclipses are partial eclipses. What factors exists on Earth that make life possible here, but unlikely on any other planet?. Which planets in the solar system are called the “gas giants” and why?. In general, what condition on the planets is MOST affected by its distance from. The Solar System. Sun, planets, moons, comets, asteroids, meteoroids.. Sun at the center.. Eight planets, thousands of asteroids, and millions of comets and meteoroids orbit the sun.. Dozens of moons orbit the planets.. Earth and Sun Relationship. Earth completes one revolution around the sun every 365 ¼ days. . Revolution – the time it takes for the Earth to complete 1 orbit around the sun.. What is Rotation?. Rotation – the Earth rotates around its axis once every 24 hours.. SC.5.E.5.1, SC.5.E.5.2, SC.5.E.5.3, SC.4.E.5.4 . Department of Science. Big Idea 5: Earth in Space and Time Benchmarks. SC.5.E.5.1. Recognize that a galaxy consists of gas, dust, and many stars, including any objects orbiting the stars. Identify our home galaxy as the Milky Way. AA . 2015-2016. Earth’s movement is constant!. Earth’s orbit. Sun is at the center. Orbit: movement of an object around another. ex: Earth orbits the Sun.. Elliptical: oval shaped. Revolution: 1 full orbit of Earth around Sun. .
