11/19 - Look over the History of Astronomy Review. Then look over your notebook and assignments. Write down at least 2 questions you have? 11/19 - What is a space probe? What are examples of space probes that were used before the moon landing in 1969? (ES pgs. 489 to 491)11/18 -
11/15 - Draw the 6 cannon ball orbits on the screen. Which paths are suborbital? Which paths are orbital?
11/14 - What is a force? What metric (SI) unit is used when measuring force? (ES pgs. 123-126)
11/13 - What are the two main types of optical telescope? How does each work? Which one did Mr. Bright bring to class?
11/12 - In your notebook:
Make an ellipse with two thumbtacks, string, and a pencil.
Label both focus points, the major axis and the minor axis.
Draw the sun at one of the focus points.
Label the Perihelion and Aphelion.
Describe the motion Kepler's second law says will happen at the Perihelion and Aphelion.
