## Lesson 1 lab – basic coordinates seasons

3 Question 5: In the two charts, how do the relative sizes of Greenland and Australia compare? Greenland (2.2 million km 2) and Australia (2.2 million km 2) have real surface area values (7.7 million km 2 ). Is each map representative of these true values? Equatorial Coordinates of the Celestial Spheres Working through the introductory material on the page titled Celestial Equator, Declination, and Right Ascension is a good place to start. Open the Flat Sky Map Explorer or the Sky Map Explorer, whatever you want. Familiarize yourself with the same set of features that were available on the previous maps (cursor movement, map moving, decimal/sexagesimal). Make sure you understand the purpose of each check box. Question 6: On this map, where is the star Polaris? What are the coordinates of this object? Question 7: Determine the right ascension and declination of the brightest stars Betelgeuse and Rigel in the constellation Orion, as shown in the box below. It’s worth noting that Orion is on the celestial equator. NAAP RA DEC RA DEC Basic Motions & Coordinates 3/8

Many of our older projects have executables (64-bit and 32-bit) for Windows and (64-bit) for Macintosh computers (NAAP, ClassAction, & Ranking Tasks). Download and update the required package for your (or your student’s) computer device locally. Please keep in mind that these are real applications that run on your native OS, and their longevity is solely dependent on your OS. For Chromebooks, there is no comparable feasible solution.
Notice that any simulation available in the past on this site is found in either the ClassAction or NAAP Labs native app. (Look under the Animations tab in ClassAction.) The following material navigation guide is given to assist you. On the NAAP Resources tab, you’ll find student and tutorial guides.

### What is the approximate longitude and latitude of the center of the island of madagascar

Name: Basic Coordinates & Seasons Student Guide This module is divided into three sections: terrestrial coordinates, celestial equatorial coordinates, and understanding how the ecliptic relates to Earth’s seasons. Each of these parts has its own simulator(s) (s). The background information required to use these resources is found in each section. Terrestrial Coordinates Work through the introductory material on longitude and latitude units, discovering longitude and latitude, and a brief history of longitude and latitude (optional). Launch the Explorer for Flat Maps. Familiarize yourself with the cursor and how it prints out the longitude and latitude of the active map spot. It’s worth noting that the map’s central meridian can be modified ( change its longitude).
Exercise #1: Astronomy Ranking Task: Motion of the Sky This is what the sky would look like for a northern hemisphere observer looking south at noon on January 1 if they could see both the Sun and the other stars during the day.
Hypothesis • There is a disparity between the subject’s difficulty and the measurement tools’ simplicity. – Typically, the only thing that can be evaluated is whether or not the individual can solve the problem. • Offers little insight into what the learner wants to do to progress, and no direction to the instructor about how to assist.

Student Guide to Basic Coordinates and Seasons This module is divided into three sections: terrestrial coordinates, celestial equatorial coordinates, and understanding how the ecliptic relates to Earth’s seasons. There is a simulator for each of these sections (s). Each section contains the necessary background information to use these tools.
Work through the introductory material on longitude and latitude units, discovering longitude and latitude, and a brief history of longitude and latitude (optional). * Launch the Explorer for Flat Maps. * Familiarize yourself with the cursor and how it prints out the active map location’s longitude and latitude. It’s worth noting that the central point can be changed.
5th question: In the two maps, how do the relative sizes of Greenland and Australia compare? Greenland (2.2 million km2) and Australia (2.2 million km2) have real surface area values (7.7 million km2). Is each map representative of these true values?
The globe map does a better job of depicting the true values of the nations, but it is also inaccurate. On a globe map, Australia appears to be 2.5 to 3 times the size of Greenland, but it is actually nearly four times the size of Greenland based on true values. Since Greenland is near the top of the chart and was thus spread out, the flat map is even more skewed. This makes it appear to be bigger than Australia.
