In order to see a scale model of the solar system, you could build one. A. travel in space to each object B. use imagination C. build one D. draw one on a sheet of paper 9. This model was built in Black Rock Desert in _______________. A. California B. Nevada C. Arizona D. New Mexico 10. Using a marble for the size of Earth, the Sun would be scaled down to about ______________. A. 1.5 meters B. 4 meters C. 5.5 meters D. 10 meters 11. On their scale model, Mercury’s orbit was ________________. away from the Sun. A. 0.92 km, or 0.57 miles B. 3.4 km, or 2.1 miles C. 68 m, or 224 ft. D. 176 m, or 579 ft. 12.

On their scale model, Earth’s orbit was __________________ away from the Sun. A. 0.92 km, or 0.57 miles B. 3.4 km, or 2.1 miles C. 68 m, or 224 ft. D. 176 m, or 579 ft. 14. On their scale model, Mars’s orbit was _________________ away from the Sun. A. 120 m, or 447 ft. B. 269 m, 881ft. C. 1.7 km, or 1.1 miles D. 3.4 km, or 2.1 miles 15.

On their scale model, Uranus’s orbit was ______________ miles away from the Sun. A. 0.92 km, or 0.57 miles B. 3.4 km, or 2.1 miles C. 68 m, or 224 ft. D. 176 m, or 579 ft. 18. In the video, they say that Neptune is the “edge of the solar system.” Although many people speak of this area as an informal edge of the solar system, since this is the last planet, it is it not truly the edge of the solar system. Our solar system includes everything that is going around our Sun. Therefore, the edge of the solar system is really about 100,000 AU from the Sun, the outer edge of the Oort Cloud. This is where long period comets come from. Beyond the Oort Cloud, gravitational pull from other stars dominate that region of space. On their scale model, Neptune’s orbit was _______________ away from the Sun. A. 120 m, or 447 ft. B. 5.6 km, or 3.5 miles C. 1.7 km, or 1.1 miles D. 3.4 km, or 2.1 miles 19. How did they know their proportions were correct as they scaled down the solar system in their model? A. The Moon blocked off the Sun, causing a solar eclipse. B. The Earth’s shadow covered the Moon, causing a lunar eclipse. C. Standing on the model of Earth’s orbit, the model Sun and the real Sun appear the exact same size. D. They double checked their math. Part 2: Website to Explore Visit the following website and answer the questions that follow. Type the below url into your browser. Website: If the Moon Were Only 1 Pixel http://joshworth.com/dev/pixelspace/pixelspace_solarsystem.html Explore this website, which shows the scale of the solar system if the Moon was scaled down to be the size of one pixel on your computer screen…that little dot they show when you start scrolling, before you actually start the model, beginning with the Sun. 20. The diameter of the Moon is 3474.8 km, which is roughly the distance from____________________________. A. Grenland to Iceland B. New York to Las Vegas C. Norway to Sweden D. San Diego to Sacramento You could scroll using the bottom of the site, but that would take you forever! I recommend that you use the small, faint, icons at the top of the page to quickly move from one object to the next. However, when you do this, pay attention to how far it is taking you in such a short time! These icons are the astronomical symbols for each object that is depicted on this site. You will notice that the icons/symbols are between two arrows. The left arrow will scroll quickly backward, and the right arrow will scroll quickly forward, to interesting text that the creator of this site has written. You don’t have to read all the humorous and eventually philosophical text, although I find it interesting! At minimum, click on each of the icons/symbols, which will take you to each of the major objects in the solar system. For example, the first icon, shown as a circle with a dot in the center represents the Sun, so it will automatically scroll you to the Sun. Remember, the point of this activity is to gain an appreciation for the scale of the solar system, so when you click on the icons/symbols, pay attention to how far it is taking you in such a short time! 21. Which planet is represented by this astronomical symbol: A. Mercury B. Venus C. Earth D. Mars E. Jupiter F. Saturn G. Uranus H. Neptune 22. Which planet is represented by this astronomical symbol: A. Mercury B. Venus C. Earth D. Mars E. Jupiter F. Saturn G. Uranus H. Neptune ☿ ♃ 23. Which planet is represented by this astronomical symbol: A. Mercury B. Venus C. Earth D. Mars E. Jupiter F. Saturn G. Uranus H. Neptune 24. Which planet is represented by this astronomical symbol: A. Mercury B. Venus C. Earth D. Mars E. Jupiter F. Saturn G. Uranus H. Neptune 25. Which planet is represented by this astronomical symbol: A. Mercury B. Venus C. Earth D. Mars E. Jupiter F. Saturn G. Uranus H. Neptune ♄ ⊕ ♆ ...
