Eclipses!For this topic you will be working at your own pace. It is expected that you will finish this work in 2-3 class periods. Please make sure that you are following the directions for each part of the assignment.
Part A - Video NotesFor this part you will need to cut and paste the Eclipse diagrams into your composition notebook.
Part B - Eclipse SimulationFor this part you will begin the animation and make observations. You will also answer the following questions in your composition notebook. (page 38 for Mrs. Ligon's class)CLICK HERE to access the simulator.1a. Where is the Moon in its orbit during a solar eclipse?1b. What is the phase of the Moon during a solar eclipse?2a. Where is the Moon in its orbit during a lunar eclipse?2b. What is the phase of the Moon during a lunar eclipse?3a. Set the size of the Moon 100%. Make sure that the "Earth-Moon Distance" is 384,000 km. Set the "Tilt of Orbit" slider to zero degrees and watch one full orbit of the Moon around Earth. Do any eclipses occur? If so, what kind of eclipse takes place?3b. Now set the "Tilt of Orbit" to about three degrees. Watch one full orbit. Do any eclipses occur now? If so, what kind of eclipse takes place?4. If real life, the tilt of the Moon's orbit is actually closer to five degrees. Should the Moon cover the Sun as it moves past? Why or why not?5a. Reset the "Tilt of Orbit" to zero degrees and arrange a perfect solar eclipse. Now vary the size of the Moon. What does a solar eclipse look like if the Moon is 20% bigger?5b. What does a solar eclipse look like if the Moon is 20% smaller?5c. Describe your observations if you change the size of the moon during a lunar eclipse.6. Reset the "Tilt of Orbit" to zero degrees, the size of the Moon to 100%. Move the "Earth-Moon Distance" slider all the way to the right and watch a solar eclipse. Describe what you see. Look at the shadow of the Moon - where does it end?7. Reset all the parameters to their defaults and watch a solar eclipse and a lunar eclipse. "Totality" defined as the amount of time that one body is completely covered by another body, either the Sun by the Moon, or the Moon by the Earth's shadow. Which is longer, the totality of a solar eclipse or a lunar eclipse? Explain why.Part C - Galileo DialogThis will be the LAST assignment you complete before you take the quiz.Galileo Dialog
This quiz score will go into GBW. If you do not receive at least 70%, you will complete ONE MORE ASSIGNMENT, then take a 2nd version of the quiz.
- Please complete the WORKSHEET that goes along with the dialog. This will be checked before you can take the quiz.
- When you are finished with the dialog - please take the quiz.
