In the first part ofthis week’s lab, we will leave Earth behind and venture to ourneighboring planet of Mars. Using Google Mars, we will explore theterrain of the Red Planet, looking at evidence of past water flow acrossits surface. In the second part of the lab, you will build aspectrometer, a device for observing the spectra of different lightsources. Spectrometers enable astronomers to determine the compositionof distant stars, as well as how far away they are from us. Before beginning this lab, take a few minutes to review the list of materials required to complete Part 2, on page 6. Your final product for this lab will be a lab report. It is notnecessary to submit this worksheet. Your report should cover all of thequestions you have answered here (in paragraph essay form, not questionand answer format). It should discuss how these two tools – Google Marsand spectrometers – can be used to study distant places (planets andstars). Part 1: Water on MarsBegin by clicking here (Links to an external site.)to open the website containing the location files you will use thisweek. Under ‘Other Materials’, click on ‘Placemarks – Mars FluvialFeatures’ to download the file to your computer. Once it is downloaded,open it, and it should open automatically in Google Earth Pro. Once Mars appears, you’ll have a different set of layers from Google Earth to explore. The Global Mapslayer can be used to change the surface layer (you may have to expandthis folder to see these options): use the radio button to choose thelayer and click the blue layer name to bring up a brief description ofthat dataset. The ‘Visible Imagery’ contains the highest qualityimages, but the Viking Color Imagery layer is more uniform and may beeasier to use in some places. The Daytime Infrared, Nighttime Infrared,and Colorized Terrain are interesting to explore but will not be usedhere.Locate the volcano Apollinaris Mons (also called Apollinaris Patera). The placemark is located on one side of the caldera: zoom out so you can see the flanks of the volcano as well.Describe the linear features that surround Apollinaris: if thesewere stream channels, what type of drainage would this be? To answerthat question, click here (Links to an external site.) to view a number of different drainage patterns; which one fits the features around Apollinaris the best? Include a simple sketch of the drainage below; take a digital photograph of your sketch to include in your lab report.Consider the material that makes up Apollinaris: what does thepresence of these linear channels suggest about the strength (ability toresist erosion) of the underlying material? Suggest an appropriatecomposition for this material as part of your answer (note the brief description given of Apollinaris in the instructions above.)Locate the feature Warrego Valles. This question is best answered using a ‘eye alt’ of about 200 km/120 miles – set your zoom level so the eye alt value in the lower right corner of the window is about 200 km or 120 miles.In the space below, sketch the general shape of Warrego Valles. Take a digital photograph of your sketch to include in your lab report. Whattype of drainage does this appear to be – and what implications doesthis have for how Warrego Valles might have formed? Again, use this resource (Links to an external site.) to help identify the type of drainage pattern present.Locate the crater Orson Welles and examine the valley that starts atthe crater’s NE rim (Shalbatana Valles). Briefly describe the valleybelow. Include a simple sketch of the valley; take a digital photograph of your sketch to include in your lab report. Identify any evidence of erosion/deposition in the valley floor and suggest a process by which this valley may have formed.Locate Noctis Labyrinthus (this feature is on the western edge of Vallis Marineris, the ‘Grand Canyon of Mars’).Assume that water has flowed through this area: what type of drainage pattern is present here? Include a simple sketch of the drainage; take a digital photograph of your sketch to include in your lab report. Again, use this resource (Links to an external site.) to help identify the type of drainage pattern present.What does this type of drainage pattern suggest about the underlying bedrock?Locate the ‘Feature in Eberswalde’, and zoom to an ‘eye alt’ of 11 miles / 18 km with the placemark in the center of the window.Sketch the feature below and suggest how it may have formed (this is very much a mystery, with no right answer). Take a digital photograph of your sketch to include in your lab report.Part 2: Light from the Stars (Building a Spectrometer)The instructions below describe how to build a spectrometer. Here is alink if you wish to view the site where the instructions are from: Lab, Camera, Action: Make your own CD spectrometer (Links to an external site.).Materials needed:A CD or DVD that can be sacrificed to this project. Old software CDROMs work great.A cereal box. Any size that can hold a CD or DVD disk will do.A sharp knife or razor blade to cut into the cereal box.Our spectroscope has three main parts. There is a slit made from arazor blade to make a path for the light, a diffraction grating madefrom a CD disk, and a viewing port.To construct your spectroscope, you need to put a slice in one sideof the box at roughly a 30-degree angle. This will hold the CD. Placethe CD in the slot to determine where to place the other two cuts. Onthe top of the box, cut a hole about half an inch to an inch squareabove the CD. On the side opposite the CD, make a very narrow slitopposite the CD. Alternatively, you can cut a larger slit, and cover itwith 2 pieces of foil to control the size of the slit. Spectroscopecomplete!Photograph your finished spectrometer and include the photo in your lab report.Once you have assembled your spectroscope with the instructions in the lecture and above, use it to examine the spectra of three different light sources.Make sure that at least one of them is the sun or moon, but the otherscan be incandescent lights, compact fluorescent bulbs, LED lights,halogen or xenon bulbs, televisions, computer screens, candles,fireplaces, etc. Aim the slit towards the light source you areinvestigating, then look through the viewing hole to see the spectrum onthe disk.Answer the following questions: Identify each light source you viewed and describe the spectra youobserved from that source. For each description, include colors, if thecolors are blended together or separated, and if the colors are fuzzyor distinct. What feature of the light source do the spectra represent? In other words, what is it that you are actually analyzing?Why do you think spectrometers are so valuable for studying celestial objects?Part 3: The ReportWrite up your lab in a well-crafted report. The report should coverall the questions from Part 1 and Part 2, along with photos of all ofyour sketches from Part 1 and of your completed spectrometer in Part 2.Also include a discussion of how these two tools for studying distantworlds, Google Mars and a spectrometer, enable us to make newdiscoveries. Please adhere to APA formatting guidelines according to theCSU-Global Guide to Writing and APA Requirements (Links to an external site.) for all three parts of this lab.
