*BIG QUIZ (or small test) on MINERALS tomorrow!  STUDY AND BE PREPARED!!!*

AGENDA:

• Finish Mineral Properties Notes
• Mineral ID Lab

HOMEWORK:

1. Mineral ID Lab Questions
2. STUDY for the Minerals BIG QUIZ - see example written answers below

SAMPLE GOOD ANSWERS FROM THE MINERAL QUIZ EARLIER THIS WEEK.  Use these as examples of how to write good written test and quiz answers.  If you know the material on minerals well, it should be easy for you to answer each question clearly and simply so STUDY!!!

1.  Which diagram shows a crystal, A or B?  Explain how you know.

     Diagram A shows a crystal because the atoms make a repeating pattern, unlike B where the atoms are random.  

2.  What is a mineral?  Be sure to name all of the criteria.

    A mineral is a naturally occurring, inorganic, crystalline solid with a definite chemical composition.

3. Why is the ice in a glacier considered to be a mineral but the water from the same glacier is not?

    Ice is a solid (which minerals must be) but the water is a liquid, therefore it cannot be a mineral.

4.  Describe the formation of minerals from magma.

    As the magma cools slowly underground the atoms begin to arrange themselves into mineral crystals until all of the atoms are part of a mineral and there is no more liquid magma left.

5. Explain how minerals form when they experience a change in pressure and temperature.

   As a mineral experiences a change in temperature and/or pressure the atoms in the mineral will tear away from the mineral and join together in a new pattern, creating a new mineral.

ECLIPSE TIMELINE: From Space.com

Stage 1 @ 1:15 a.m. PDT: Moon enters penumbra — The shadow cone of the Earth has two parts: a dark, inner umbra, surrounded by a lighterpenumbra. The penumbra is the pale outer portion of the Earth's shadow. Although the lunar eclipse begins officially at this moment, this is, in essence, an academic event. You won't see anything unusual happening to the moon — at least not just yet. The Earth's penumbral shadow is so faint that it remains invisible until the moon is deeply immersed in it. We must wait until the penumbra has reached roughly 70 percent across the moon's disc to be able to discern the Earth's shadow. For about the next 40 minutes, the full moon will continue to appear to shine normally, although with each passing minute, it will be progressing ever deeper into the Earth's outer shadow.

Stage 2 @ 1:56 a.m. PDT: Penumbral shadow begins to appear — Now,the moon has progressed far enough into the penumbra so that it should be evident on the moon's disc. Start looking for a very light shading to appear on the moon's upper-left portion. This will become increasingly evident as the minutes pass; the shading will appear to spread and deepen. Just before the moon begins to enter the Earth's dark umbral shadow, the penumbra should appear as an obvious smudge or tarnishing of the moon's left portion.

Stage 3 @ 2:14 a.m. PDT: Moon enters the umbra — The moon now begins to cross into the Earth's dark central shadow, called the umbra. A small, dark scallop shape begins to appear on the moon's upper-left-hand limb. The partial phases of the eclipse begin, the pace quickens and the change is dramatic. The umbra is much darker than the penumbra and fairly sharp-edged. [Oct. 8 Total Lunar Eclipse Explained (Video)]

As the minutes pass, the dark shadow appears to slowly creep across the moon's face. At first, the moon's limb may seem to vanish completely inside of the umbra, but much later, as it moves in deeper, you'll probably notice it glowing dimly orange, red or brown. Notice also that the edge of the Earth's shadow projected on the moon is curved. Here is visible evidence that the Earth is a sphere, as deduced by Aristotle from Iunar eclipses he observed in the 4th century B.C. It's almost as if a dimmer switch were slowly being turned down on the surrounding landscape, as deep shadows of a brilliant moonlit night begin to fade away.

Stage 4 @ 3:07 a.m. PDT: 75-percent coverage — With three-quarters of the moon's disc now eclipsed, the part of it that is immersed in shadow should begin to light up very faintly, similar to a piece of iron heated to the point where it just begins to glow. It now becomes obvious that the umbral shadow is not complete darkness.

Using binoculars or a small telescope, its outer part is usually light enough to reveal lunar seas and craters, but the central part is much darker, and sometimes no surface features are recognizable. Colors in the umbra vary greatly from one eclipse to the next. Reds and grays usually predominate, but sometimes browns, blues and other tints are encountered.

Stage 5 @ 3:21 a.m. PDT: Less than 5 minutes to totality — Several minutes before (and after) totality — the point at which the moon's disc is completely eclipsed — the contrast between the remaining pale-yellow sliver and the ruddy-brown coloration spread over the rest of the moon's disc may produce a beautiful phenomenon sometimes referred to as the "Japanese Lantern Effect."[How to Photograph the Lunar Eclipse]

Stage 6 @ 3:25 a.m. PDT: Total eclipse begins — When the last of the moon enters the umbra, the total lunar eclipse begins. How the moon will appear during totality is not known. Some eclipses are such a dark gray-black that the moon nearly vanishes from view. At other eclipses, it can glow a bright orange. The reason the moon can be seen at all when it's totally eclipsed is that sunlight is scattered and refracted around the edge of the Earth by our atmosphere. To an astronaut standing on the moon during totality, the sun would be hidden behind a dark Earth outlined by a brilliant red ring consisting of all the world's sunrises and sunsets. [Amazing Total Lunar Eclipse Photos of April 2014]

The brightness of this ring around the Earth depends on global weather conditions and the amount of dust suspended in the air. A clear atmosphere on Earth means a bright lunar eclipse. If a major volcanic eruption has injected particles into the stratosphere during the previous couple of years, the eclipse is very dark. As of this writing, three significant volcanic eruptions have occurred pretty recently — Mount Ontake in Japan, Mount Mayon in the Philippines and Mount Bardarbunga in Iceland — so it will be interesting to see if this eclipse will appear a bit darker than normal.

Stage 7 @ 3:55 a.m. PDT: Middle of totality — At this point, the moon is shining anywhere from 10,000 to 100,000 times fainter than it was just a couple of hours ago. Since the moon is moving to the north of the center of the Earth's umbra, the gradation of color and brightness across the moon's disc should be such that its lower portion should appear darkest, with hues of deep copper or chocolate brown. Meanwhile, its upper portion — the part of the moon closest to the outer edge of the umbra — should appear brightest, with hues of reds, oranges and even perhaps a soft bluish-white.

Observers away from bright city lights will notice many more stars than were visible earlier in the night. The moon will be in the constellation of Pisces, with the faint planet Uranus positioned roughly a half degree to the moon's left and readily seen with binoculars. In the eastern United States, the moon will be setting as the sun is rising.

The darkness of the sky is impressive. The surrounding landscape has taken on a somber hue. Before the eclipse, the full moon looked flat and one-dimensional. During totality, however, it will look smaller and three-dimensional, like some weirdly illuminated ball suspended in space.

Before the moon entered the Earth's shadow, the temperature on its sunlit surface hovered at 266 degrees Fahrenheit (130 degrees C). Since the moon lacks an atmosphere, there is no way that this heat can be stopped from escaping into space as the shadow sweeps by. Now, in shadow, the temperature on the moon has dropped to minus 146 F (minus 99 C) — a drop of 412 F (229 C) in less than 90 minutes!

Stage 8 @ 4:25 a.m. PDT: Total eclipse ends —The emergence of the moon from the shadow begins. The first small segment of the moon begins to reappear, followed again for the next several minutes by the Japanese Lantern Effect.

Stage 9 @ 4:42 a.m. PDT: Seventy-five percent coverage — Any vestiges of coloration within the umbra should be disappearing now. From here on, as the dark shadow methodically creeps off the moon's disc, it should appear black and featureless. For parts of the Great Lakes, Midwest, Tennessee and Mississippi Valley, the moon will either have set or will be approaching its setting as the sun comes up in the East.

The total lunar eclipse of Oct. 8, 2014 will be visible from a wide area on Earth, as shown in this visibility map from released by Sky & Telescope Magazine.

Stage 10 @ 5:34 a.m. PDT: Moon leaves umbra — The dark central shadow clears the moon's right hand (western) limb.

Stage 11 @ 5:51 a.m. PDT: Penumbra shadow fades away — As the last, faint shading vanishes off the moon's right portion, the visual show comes to an end.

Stage 12 @ 6:33 a.m. PDT: Moon leaves penumbra —The eclipse "officially" ends, as the moon is completely free of the penumbral shadow.
