FULL name Standard 1: Solar System Write Y = yes, N = no in the blank spots. If unsure, go to the section # and see if you can answer the questions. 1. “I can” describe the steps of how the solar system formed. 2. “I can” identify the evidence used to support how the solar system formed. 3. “I can” define the laws that govern the motions in the solar system. 4. “I can” explain the evidence used to date the age of the solar system and Earth. 5. “I can” compare the Earth to other objects in the solar system in terms of mass, volume, density, composition, gravity, temperature, and distance to the sun. 6. “I can” indicate where the heavy elements on Earth came from. 7. “I can” provide an example of how technology has helped scientists investigate the universe. 8. “I can” specify the conditions that support life on Earth, including the goldilocks zone. 1.

Shines 4. Fully formed ecliptic 5. Friction causes heat 6. Leftover gas is swept away 7. Spin-up effect 8. Static electricity collects dust 9. Asteroid size/shape 10. Remains from a star’s death 11. Violent collisions 3 6 1 4 7 2 5 8 2. Evidence that Supports the Nebular Theory 1. The ecliptic is a direct result of which stage of the solar system formation. 2. Explain how this is evidence of the nebula theory. 3. How can technology be used to find evidence of the processes solar systems undergo when forming. 3. Motions and Governing Laws Level of Understanding: OR Label the orbit with the correct forces along the arrows. VOCABULARY In other words, can you define these? 1. Gravity 2. Inertia 3. Orbital Period 4. Axial Rotation 5. Orbit 6. Law of Ellipses 7. Eccentricity 8. Law of Equal Areas 1. How does angular momentum affect a nebula that is contracting inwards. 2. According the equation for gravity, what are the 2 factors gravity is dependent on: 4. Which direction does gravity pull? 5. Which direction does the solar system spin? Johannes Kepler Kepler, was the first astronomer to mathematically prove Copernicus’s new heliocentric model was possible. 6. Draw a Heliocentric model: 7. How is this the opposite from a Geocentric model? Since geometry is co-eternal with the divine mind before the birth of things, God himself served as his own model in creating the world. Johannes Kepler,1618 3. Which of those 2 factors does this picture represent? 8. Name the 3 laws that Kepler came up with: 9. Draw an elliptical orbit around a sun. 10. Draw a highly eccentric orbit around a sun. 11. Homework: What is the reason for the seasons on Earth? 4. Evidence used to Date the Earth and Solar System Level of Understanding: OR 1. What is the age of the Earth and the Solar System? VOCABULARY In other words, can you define these? 1. Absolute Age 2. Radiometric Dating 3. Isotopes 4. Beta Decay 5. Alpha Decay 6. Gamma Decay 7. Half-Life 2. Is that a type of absolute age or relative age? 3. List the 4 main evidences we use to determine the age of the solar system. 4. These microcrystals called rocks on Earth and meteorites to test the amount of (parent isotope) compared to the amount of (daughter isotope). 5. What are Chondtites: are pulled from Label the sub-atomic parts of the atom. 10. Define Radiometric Dating: = = 6. If you change the atom’s # of protons, what = happens? 7. If you change the atom’s # of neutrons, what = happens? In the movie: Clean Room 8. If you change the atom’s # of electrons, what happens? 7. Why is relative dating, or dating of rock layers not as accurate as absolute dating? 9. Explain how the coin tossing activity in class demonstrated the of radioactive elements. decay rate 8. Why was a clean room necessary in order to determine the true age of the Earth? 5. and 6. Comparing the Planets and Elements in the Solar System 1. Where do heavy elements come from? 2. What are the 2 most abundant elements in our Solar System? 3. What percentage of mass is in the Sun compared the rest of the Solar System? 4. What is an Astronomical Unit? 5. Which planet is the most dense? 6. If a flower growing on Jupiter, had all the same living conditions as on Earth (temp., sunlight, nutrients, soil, etc.), would it be shorter, the same size, or taller? Explain. 7. What 2 elements are the cores of terrestrial planets made up of: 8. What 2 elements are the atmospheres of gas planets made up of: Frost Line and characteristics of the planets. 10. The x-axis on the graph represents: 11. The y-axis on the graph represents: 12. Study both the Table and Graph and identify why the rock planets are near the sun and why the gas planets are further away. Planetary Differentiation Look at this picture: 13. Name 2 similarities 14. Name 2 differences 9. What is the percentage of each: % % 15. What caused the different layers to form on each planet? When did this take place? 16. How does composition of a planet affect its density? 17. How does the mass of a planet affect the number of moons it has? 7. Space Technology 1. List specific examples of space technology that has allowed us to further our understanding of our solar system. What did we learn from it? 2. What is the furthest we have sent space craft within our solar system? 8. Life on Earth… Life in the Universe… 1. What is the Goldilock Zone (habitatble zone)? 2.
