Slytherin Time: Midnight
Welcome back to Hogwarts, everyone! I hope that you had a wonderful winter break. I thought that I would test your memory on the vocabulary we have learned. For this, I'm going to give you a list of terms and a list of definitions. You must match the two together. To make it extra tricky, I'm going to throw in one extra term and one extra definition that don't match. You will have to tell me which these are!
You have half an hour.
List of Vocabulary Words:
- Azimuth
- Declination
- Meridian
- Sidereal
- Zenith
- Constellation
- Latitude
- Orbit
A. Point on the sky directly overhead.
B. Related to the stars. Thus sidereal day, month, period, year: lengths of time intervals specified by motion of some object relative to the stars, as opposed to apparent lengths of those time intervals that will depend on the Earth’s own movements.
C. Path traced out by one object around another
D. Coordinate used to specify the position of a point or direction around (or parallel to) an equator.
E. Angle measured clockwise around the horizon, from 0* towards the north, through 90* to the east, 180* to the south, 270* to the west, and to 360* due north
F. A group of stars that seemed to suggest the shape of some god, person, animal or object. Now a term used to designate a region of the sky. There are 88 constellations.
G. Coordinate used to measure (in degrees) the angular distance of a point or celestial objects above or below an equator.
H. Angular distance of an object north or south of the celestial equator, measured in degrees. Thus the north celestial pole has a declination of +90 degrees.
Half an hour is now up! Please bring me your papers and then go outside. I want you to try to name all the constellations you can find out there. Write down a list and bring it back to me before going off to bed. Good night!
