Paper 1:This Tutorial contains 1 Observation Sheet

Paper 2: Visit a planetarium

Paper 3: Visit a planetarium

Alternative Assignment

o Visit a planetarium or observatory in your area.

o Write a 1,050- to 1,400-word report describing your experience:

• The name of the facility and its association

• The type of equipment

• Showings (celestial objects observed)

• Other things learned about astronomy

• You can also include any planetarium show or videos you watched during your visit.

Observation Instructions

If you have a pair of binoculars or a camera that can be used at night, feel free to use them to enhance or record your experience.

At a minimum, you should try to note the following:

1. The Moon and its phase

a. Try to observe at least three lunar features such as named craters, lunar maria, phase, and mountainous areas (see Section 7.2 of the text).

b. Determine the time of moonrise and, if possible, the distance between Earth and the Moon on the particular date of viewing.

2. The North Star (Polaris): the associated constellations of Ursa Minor and Ursa Major (also known as the Little Dipper and the Big Dipper).

3. See Figure 2.11(a) in text. Note the position of the two constellations at two separate times and draw a chart as shown in Figure 2.11.

4. Identify at least four other constellations.

a. Note if they are in the Zodiac.

b. Note the time, position (direction), and approximate elevation above the horizon.

5. Determine whether the Milky Way is visible and, if so, its orientation (see Ch. 2).

6. Identify and observe at least two planets and describe their movement over your weeks of observation.

7. Note any other observed celestial objects or phenomena, such as meteor showers, comets, and satellites.

8. Record meteorological conditions, such as cloud cover, lightning, and light pollution.

Assignment Instructions

Create a chart or table for your observations each week. You can use the one below or create your own (the contents in left column came from the information above).
