Lunar eclipse viewing cancelled
I cancelled the lunar eclipse viewing based on weather reports--and btw, so did the Mt. Diablo Astronomical Society-- but it's clear right now. Please make sure you look at the real thing tonight.

Asteroids: Deadly Impact
Homework from previous class is due.
Your task today is to watch "Asterpoids: Deadly impact."
As you watch, come up with 10 substantial questions about science from the video. Include answers.
If papers are identical, writers will share the credit...so make sure your list of questions is unique!
Answer this question: what does this movie have to do with the moon?
Turn this in to the sub.
===============
Class work following the movie:
Page 37, 12-22.
Page 38, 34-45.
If not finished, the work should be brought back on Wednesday as homework.

Adjusted sundial due date; moon drawings due
This is the real due date for the sundials. Leave them on the back counter.
Give the moon drawings to the sub.
During class, please do the following:
On page 134, see the picture labeled 5-17. Using the techniques I showed you in class, draw this photo on a blank sheet of paper. Label the Bay of Rainbows and the crater Plato in the crater. Using the moon map in the classroom, identify the three large craters near the right side of Mare Imbrium.
Indicate in your drawing: 1) the direction of sunlight. 2) whether the sun appears higher in the sky on the left side of the picture or the right side of the picture. 3) Explain what the dark zone on the right side means.
2nd assignment:
Work on following assignment from text:
Page 143 Review questions 10-17
Page 144 Advanced questions 21-27
Page 144 What if? ... Choose one of the questions 35-40 and write an essay in response to it. Essay should be roughly one page long handwritten.
The sub will be instructed to decide whether or not you get to finish this at home or turn it in at the end of class. The sub will be more likely to let you have more time if you DO NOT TALK and STAY ON TASK during class. I will abide with the sub's decision.

Sundials due
Sundials are due
I made a mistake in the formula I gave some of you for determining horizontal sundial angles. The correct formula is
Tan (D)=tan(t)sin(phi)
where phi is always 38 - your latitude
t is the hour angle (15 = 1 oclock, 30 = 2 oclock, etc.)
D is the angle of the hour line on the equatorial dial.
=========
We learned how to draw craters today as well.
Homework: draw an imaginary crater surface with examples of overlapping craters, craters with central peaks, mountain ranges and canyons. Use at least 4-5 craters, indicate the direction of sunlight and your point of view.
JA

Lunar Surface Features
We learn about 20 lunar surface features for a quiz.
Terms: crater, ray, mare, highlands.
Once we practice the lunar surface features, we will learn about the moon phase observing project.
Then we will watch a video about the astronauts who went to the moon (To the Moon) or we will learn how to draw moon craters...the class will decide which thing we do next.
Test is not graded yet.

Quiz!
Finally...our quiz on the sun. Bring calculators!
After the quiz: introduction to the moon phase observing project.
