Name: Basic Coordinates & Seasons – Student Guide There are three main sections to this module: terrestrial coordinates, celestial equatorial coordinates, and understanding how the ecliptic is related to seasons on the Earth. Each of these sections has its own simulator(s). The background material necessary to utilize these tools is contained in each section. Terrestrial Coordinates Work through the explanatory material on units of longitude and latitude, finding longitude and latitude, and a bit of history (optional). Open the flat map explorer. Familiarize yourself with the cursor and how it prints out the longitude and latitude of the active map location. Note that you can vary the central meridian of the map (i.e. change its…show more content…
What does the shape look like? Describe the ecliptic in terms of its average and range of declination values. Approximate Date March 21 June 21 Right Ascension Declination Seasons and the Ecliptic Work through the introductory material on the page entitled Orbits and Light. Open the Seasons and Ecliptic Simulator. Note that there are three main panels (left, upper right, and lower right) each of which have two different views. Controls run along the bottom of the simulation that affect more than one panel. Click animate and then move through the six views to get an overview this simulator’s capabilities. We will address each of these six views separately. Experiment with the various methods to advance time in the simulator. You may click the start animate/stop animation button, drag the yearly time slider, or drag either the sun or the earth in the left panel to advance time. Note that this animation does not illustrate the rotation of the earth. Because the timescales of rotation and revolution are so different, it isn’t possible to effectively show both simultaneously. NAAP – Basic Coordinates & Motions 4/8 Left Panel – Orbit View Practice clicking and dragging in this panel to change the perspective. Change the perspective so that you are looking directly down onto the plane of the Earth’s orbit Click labels. Note that you can see how the direct rays of the sun hit at
