Ellipse - _________________________________________________________________________________________ Galileo’s Evidence ~___________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ Lesson 2 Introducing the Solar System EQ: What makes up the solar system? ~___________________________________________________________________________________________ ____________________________________________________________________________________________ 1. Distances within the solar system are so large that scientists use the ____________________________________________________________________________________________________________________________________ ____________________________________________________________________________________________ 2. The solar system extends more than __________________________________________ from the sun. 3. At the center of our solar system is the _______________________. 4. The sun is a million times the _______________________________________________, but is actually a very ordinary ____________________________________________________. 5. Planet - ________________________________________________________________________________________ ____________________________________________________________________________________________ 6. First 4 planets: ____________________ __mostly___________________________________________________ Last 4 planets: ____________________ __mostly___________________________________________________ 7. Dwarf planet - ___________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ 8. Except for Mercury and Venus, every planet in the solar system has at least __________________________________ ____________________________________________________________________________________________ 9. The solar system also includes many smaller objects that orbit the sun, such as _______________________________ ____________________________________________________________________________________________ EQ: How did the solar system form? ~___________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ 10. Planets formed as ________________________________________________________________________________ 11. Inner Planets: mass ____________________ gravity ___________________ ________________ and _________________ Outer Planets: mass _____________________ gravity ____________________ __________________________ planets ___________________________ planets Lesson 3 The Sun EQ: What is the structure of the sun? ~___________________________________________________________________________________________ ____________________________________________________________________________________________ 1. Sun’s mass: ¾ ___________________________ ¼ ___________________________ 2. Core – central region where the sun produces energy in the process of __________________________________________________________________________________________________________________________________ 3. Radiation zone - __________________________________________________________________________________ ____________________________________________________________________________________________ 4. Convection zone - _________________________________________________________________________________ ____________________________________________________________________________________________ Sun’s Atmosphere ~___________________________________________________________________________________________ ____________________________________________________________________________________________ _______________________________________________ - inner layer of the sun’s atmosphere _______________________________________________ - middle layer _______________________________________________ - outer layer EQ: What features can you see on the Sun? ~___________________________________________________________________________________________ ____________________________________________________________________________________________ 1. Sunspots - _______________________________________________________________________________________ ____________________________________________________________________________________________ Lesson 4 The Inner Planets EQ: What do the inner planets have in common? ~___________________________________________________________________________________________ 1. The 4 Inner Planets: ______________________________________________________________________________ 2. The inner planets are called the ___________________________________________ which means _______________ 3. Inner Planets: ___________________ densities rich in ___________________________________________ ____________________ surface have _______________________________, except Mercury EQ: What are the characteristics of the inner planets? Mercury ~___________________________________________________________________________________________ ____________________________________________________________________________________________ 4. Mercury’s surface - _______________________________________________________________________________ 5. Mercury’s atmosphere - __________________________________________________ Venus ~___________________________________________________________________________________________ ____________________________________________________________________________________________ 6. Venus is called “Earth’s twin” because it is similar to the Earth in ____________________________________________ ____________________________________________________________________________________________ 7. Venus’s atmosphere - _____________________________________________________________, and is mostly ____________________________________________ 8. Venus is __________________ to the sun than Earth so it receives more ___________________________ than Earth. Earth ~___________________________________________________________________________________________ ____________________________________________________________________________________________ 9. Earth’s 3 main layers: ______________________ ______________________ ______________________ 10. Earth is the only planet with an atmosphere that is rich in ___________________________ 11. Both Venus and Earth experience a ___________________________________________________________ Mars ~___________________________________________________________________________________________ ____________________________________________________________________________________________ 12. Mars is called the “_______________________________” due to the ______________________________________ ____________________________________________________________________________________________ 13. Scientists think that ______________________________________ flowed on Mars’s surface in the distant past, but is now frozen in the planet’s two __________________________________________________________________ 14. Some regions of Mars have giant _____________________________________________ Lesson 5 The Outer Planets EQ: What do the outer planets have in common? ~___________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ 1. The 4 Outer Planets: ______________________________________________________________________________ 2. The outer planets are called _________________________________ because ________________________________ 3. Outer Planets: strong _____________________________________________________ outer layers _________________________________________________ many ________________________________ surrounded by _________________________ of ice and rock EQ: What are the characteristics of each outer planet? Jupiter ~___________________________________________________________________________________________ 4. Jupiter’s atmosphere - _____________________________________________________________________________ 5. Jupiter’s moons - _________________________________________________________________________________ Saturn ~___________________________________________________________________________________________ 6. Saturn is the _____________________________________________________________________ in the solar system. 7. Saturn’s rings are made of __________________________________________________________________________ 8. Saturn has the lowest __________________________________ of any planet. 9. Uranus looks __________________________________ because of ________________________________________ in its atmosphere. 10. Uranus rotates from _______________________________ instead of from __________________________________, as other planets do. Neptune ~___________________________________________________________________________________________ 11. Neptune is similar in size and color to _____________________________________ 12. Neptune’s hot interior produces _____________________________________________________________________ Lesson 6 Small Solar System Objects EQ: How do scientists classify small objects in the solar system? ~___________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ 1. Most small objects in the solar system are formed in 3 areas: _____________________________________________ _____________________________________________ _____________________________________________ 2. The asteroid belt is located between __________________________________________________________________ 3. 5 dwarf planets: _________________________________________________________________________________ 4. Like planets, dwarf planets can have _________________________, Pluto has _______________________________ 5. Comets - _______________________________________________________________________________________ ____________________________________________________________________________________________ 6. Asteroids - ______________________________________________________________________________________ ____________________________________________________________________________________________ 7. Scientists hypothesis that asteroids are _______________________________________________________________ ____________________________________________________________________________________________ 8. Most asteroids orbit the sun in the ____________________________________________________________________ 9.
