Models of the Solar System Geocentric Order of the Planets Kuiper Belt Heliocentric Planet Asteroid Belt Kepler’s 3 Laws Dwarf planet (Planetoid) Oort Cloud Asteroids Ceres, Pluto, Eris Inner planets (terrestrial) Meteor Planetesimal Outer planets (gas giants) Meteorite Exoplanet Big Bang Theory Meteoroid Comet 1) Describe how the solar system formed 2) Describe how the universe formed 3) Explain a few of the ideas about the formation of the solar system 4. Stars Nebula Nuclear fusion Main sequence stars Protostar White dwarf Black dwarf star Supernova Black hole Red supergiant Red giant 4) Be able to explain how a star forms (star life cycle) 5) Know the Life Cycle of a Star 6) What does the mass of a star determine? 7) Main Sequence stars 8) H-R Diagram 9) Explain the statement “we are all stardust” 10) How can the lifecycle of a star be tracked on the HR diagram? 11) Why can fusion happen in stars? E. Solar System 12) List the planets in order, with the Kuiper Belt, Asteroid Belt, and Oort Cloud 13) Explain what is the Kuiper Belt, Asteroid Belt, Oort Cloud 14) Describe how our solar system formed 15) What is an Astronomical Unit (AU)? Why do we use AU as a measurement? What is it equal to? 6. The Sun Radiant energy Infrared light Solar wind Visible light Auroras Solar storm 16) Know the layers of the sun (core, radiative zone, convective zone, photosphere, chromosphere, corona 17) Know the surface features of the sun (sun spots, solar flares, solar prominence, 18) Be able to describe the Sun’s effects on the Earth (energy, weather, auroras, etc) G. The Moon 19) What is it 20) What are the 8 phases of the moon, in order? Draw and label each one 21) Why do we see phases? H. Eclipses and Satellites Solar Eclipse Lunar Eclipse Umbra Partial vs full solar eclipse Path of Totality Penumbra Natural satellite Artificial satellite 22) Use labeled diagrams to demonstrate how each of the following occurs. Put the sun, moon, and earth in the correct order a. Lunar eclipse b. Total solar eclipse 23) Sketch a picture of what a total solar eclipse looks like to an observer on Earth. 24) Which phase of the moon do solar and lunar eclipses happen in? 25) Why don’t we see a lunar eclipse more often? Life Cycle of a Star Review Part 1 - Sequencing Directions: The stages below are not in the right order. Number the stages in the correct order. _____ The star begins to run out of fuel and expands into a red giant or red supergiant. _____ Stars start out as diffused clouds of gas and dust drifting through space. A single one of these clouds is called a nebula _____ What happens next depends on the mass of the star. _____ Heat and pressure build in the core of the protostar until nuclear fusion takes place. _____ The force of gravity pulls a nebula together forming clumps called protostars. _____ Hydrogen atoms are fused together generating an enormous amount of energy igniting the star causing it to shine. I. Space Math 1. Convert these distances a. 12 ly = __________________ AU b. 325 ly = __________________ AU c. 5.6 x 1025 km = __________________ AU d. 12 AU = ___________________ km e. 0.6 AU = __________________ km f. 250 AU = _________________ ly Conversion practice: 1. Write in scientific notation a. 92 million = ____________________ b. 521 = _____________ c. 456 000 = _________________ 2. Convert to Astronomical Units (AU) a. 7.6 x 1015 km = _______________ b. 2.19 x 108 km = _______________ 3. Convert to Light years (ly) a. 5 x 1090 km = _________________ b. 45 AU = ______________________ 4. Convert to kilometers (km) a. 1090 AU = ______________________ b. 4.2 ly = _________________________
