Lunar Phases interactive [|http://highered.mcgraw-hill.com/sites/007299181x/student_view0/chapter2/lunar_phases_interactive.html#] Earth orbiting Sun and the seasons animation [] Start the animation and observe how and why the seasons change as the Earth orbits the Sun. More in-depth look at the reason for the seasons []
 * Links used in class: **

Determine the rising and setting times for each phase. [] // Select “view” the animation and choose caption (the button on the lower left in the tool bar) It’s just over a minute long. Watch it a few times. // QUESTION: What is the ‘remarkable coincidence’ that allows us to view a total solar eclipse? (You will be surprised!) QUESTION: What is the frequency of total solar eclipses?
 * Activity: Phases of the Moon diagrams. ** Determine orientation of Earth, Sun and Moon for each phase
 * Excellent solar eclipse animation by NOVA with subtitles **

[] Select “view” and watch with captions (the button on the lower left in the tool bar) The first part of it is the same as what you watched previously. The account of the eclipse of the century begins right after that. Remember to select and read the captions!
 * Eclipse of the Century **

[] QUESTION: What is an annular eclipse and how is it different from a total solar eclipse? QUESTION: Why can’t the Sun’s corona be seen? QUESTION: How do you think astronomers know exactly when eclipses will happen, their exact paths, time and duration (how long they last)?

 * VOCABULARY: **

- Where is the Sun overhead... on the Summer Solstice? on the Winter Solstice? on the spring and fall equinoxes? - When and where does the Sun never rise? - What causes the seasons? - When (what time of year) is the best time to see your birth constellation of the zodiac in the evening sky? - What is the geometry of the Earth, Sun and Moon when there is a.... full moon? new moon? first quarter moon? last quarter moon? waning crescent? waxing crescent? - What are the conditions for a lunar eclipse? a solar eclipse? (what is the phase of the moon for each)? - Why do lunar and solar eclipses not happen every month? - When is an object like the Sun, the Moon, a planet or a star at its highest in the sky? - Why is it possible to have a total solar eclipse? What mathematical coincidence is responsible? - What would it be like on Earth if the axis were not tilted? - How do you use a star finder?

__ ** RESEARCH PROJECT: TIMELINE OF EARTH HISTORY ** __


 * Using the resources provided below (highlighted in yellow) develop your own timeline of Earth's history. **
 * Your final product may be a Powerpoint, Prezi or any other software that's available on your laptop **


 * Each geologic period will have three aspects: **
 * - Geology ** - mountain-building events, position of continents, etc. What is going on with the Earth's crust?
 * - Plants and animals (life) ** - What was living and thriving during that time period? What became extinct?
 * - Climate ** - Based on evidence, what do scientists think the climate was like during the specific time period?

// Information about the Precambrian time period will be different from the other periods as we have only scant evidence //

Create one to three slides for each of the following geologic time periods ** (below). __Your goal should be to get near end of the Paleozoic Era by Friday.__ We will be spending more time on this during upcoming class periods and will have completed the entire Earth history. Save your images in a folder so you can make selections. Your text should be limited to one or two sentences for each of the three aspects mentioned above. Text should be IN YOUR OWN WORDS. If I see text that looks copied and pasted, I will challenge you on it. Know what you are including in your presentation. **

Each slide will be graded on the following criteria: - accuracy of information - creativity shown in assembling the information - text (no more than 2-3 sentences or bullet points) in your own words
