SKY FAMILIARIZATION WITH THE SC001 STAR CHART PHYS 1404 - SCALE MODEL OF THE SOLAR SYSTEM NAME _____________________________ DATE:_______________ CLASS:___DAY ___NIGHT In this laboratory activity, you will investigate the concepts of relative size and distances of the planets by constructing a scale model of the solar system. Part One – Sizes of the Planets You’ve been hired by the college to construct a scale model of the solar system on the Navarro College Waxahachie campus. You must place each planet in the model to be constructed in such a way as to demonstrate to the public the proper dimensions of each world. In this part of the lab, you will calculate the relative sizes of Solar System objects if we were to shrink the Earth down to a diameter of 1 inch. Complete the table below… PLANET REAL DIAMETER (KILOMETERS) MODEL DIAMETER (MM) MODEL DIAMETER (METERS) Sun 1,400,000 Mercury 4,878 Venus 12,104 Earth 12,756 25 Mars 6,786 Jupiter 142,984 Saturn 120,536 Uranus 51,118 Neptune 49,532 Part Two – Distances to the Planets In this part of the lab, you will decide where to place each planet on the Navarro College campus to demonstrate the relative distances from the Sun. You have been provided with a campus map with a distance line drawn from the flagpole in front of the A Building. . Place your “Sun” in front of the flag pole in front of the A Building and align your solar system along John Arden Drive going towards Carlisle Chevrolet. Notice that each mark on the distance line is 1 astronomical unit (AU) and that Earth’s position is already labeled. On this line, 1 AU = 100t. Use this information to complete the table below. PLANET DISTANCE (AU) DISTANCE (METERS from A) Mercury 0.387 Venus 0.723 Earth 1 100 Mars 1.524 Jupiter 5.203 Saturn 9.539 Uranus 19.191 Neptune 30.061 Part Three – Label the Campus Map Using the distance value for each planet in the table above, place a marker for each planet on the distance line on the provided campus map. In this way, you will have a visual representation of the Navarro College campus Solar System Model that could be used to determine where to place each planet model at its proper distance. Make sure that you label each location with the planet’s name. PHYS 1404 - SCALE MODEL OF THE SOLAR SYSTEM NAME _____________________________ DATE:_______________ CLASS:___DAY ___NIGHT QUESTIONS 1. Which planets have orbital positions that never travel beyond the far end of the C-building parking lot in your model? ______________________________________________________________________________ ______________________________________________________________________________ 2. Which planet could you encounter just past where IH-35 and TX-287 cross? ______________________________________________________________________________ 3. Between which two buildings on campus would you expect to see the model of Venus? ______________________________________________________________________________ ______________________________________________________________________________ 4. Which planet’s orbit would pass through the Carlisle Chevrolet parking lot? ______________________________________________________________________________ 5. Which planet model would you expect to inside the A building? ______________________________________________________________________________ 6. Does Saturn’s orbit cross Ovilla Rd ALONG the scale? ______________________________________________________________________________ 7. Which planet model(s) could cross Ovilla Rd ANYWHERE along Ovilla Rd? ______________________________________________________________________________ 8. Label the location at which each planet that crossed Ovilla Rd would actually cross the road. Assume circular orbits. ______________________________________________________________________________ 9. Which planet, as it moves in its orbit, would pass just inside the marker for Owens Croning? ______________________________________________________________________________ 10. Which planet, as it moves in its orbit, would pass just beyond the marker for Baylor Scott and White? ______________________________________________________________________________ PHYS 1404 - SCALE MODEL OF THE SOLAR SYSTEM NAME _____________________________ DATE:_______________ CLASS:___DAY ___NIGHT Plot the INNER Solar System PLUS Jupiter on THIS map. The Earth and the Sun are already marked for you. PHYS 1404 - SCALE MODEL OF THE SOLAR SYSTEM NAME _____________________________ DATE:_______________ CLASS:___DAY ___NIGHT Plot the OUTER Solar System on THIS map (INCLUDE JUPITER). The Earth and Sun are already marked on the scale for you. Don’t forget in Question 8 to mark those planet positions as they would cross Ovilla Rd as well. Homework 2 Mercury Venus and Mars 1. Which of the following is NOT one of the key reasons that so many spacecraft from Earth have visited Venus and Mars? they are the two planets closest to the Earth they resemble the Earth in a number of significant ways their atmospheres are very similar to the Earth in terms of their chemical make-up both have tantalized us when seen through a telescope -- one because it is perpetually covered by clouds, the other because it shows seasonal changes they each have a solid surface on which we can trace their geological history   2 .What planet can come closest to the Earth in its orbit and look brightest in our skies? Venus Mars Mercury Jupiter none of the above   3. The same gas makes up most of the atmosphere of Mars and Venus. This gas is: water vapor nitrogen ozone ammonia gas carbon dioxide   4 The planet that most resembles the Earth in size and internal composition is Mars Venus Mercury Jupiter the Moon 5.I want to examine the surface of a planet which is completely covered by a thick layer of clouds all the time. What wavelength of electromagnetic radiation would I be smartest to use: visible light x-rays radio waves (like radar) any of the above would work none would work   6.  What is the cause of the weird terrain on one side of the planet Mercury posing the caloris basin?     PreviousNext
