Homework #3 (25 Points) Due Tuesday Sep. 26
Unit 10, Problem 1; Unit 14, Problem 1; Unit 16, Problem 1; Unit 18, Problem 2; Unit 20, Problem 3.
Extra Credit (5 Points): Feeling stressed? Slam some asteroids and comets into the Earth and see what happens on the "Solar System Collisions" webpage (Follow the Computer Programs - Practice link or go directly to the Impact page). Describe what happens -- and how often -- for asteroids of several different sizes (small, medium, large, HUGE!). Imagine a rocky asteroid moving at 25 km/s, how big does it have to be to create a magnitude 9.5 earthquake?
Extra Credit (5 Points): Explore the
Astronomy
JavaLab. Choose one of the Applets there and explore its function.
Report on which one you chose and why, as well as what you learned.
Extra Credit (5 Points): Follow the
artificial satellite
link and use the
resources you find to choose a man-made satellite to observe yourself.
Then go out and watch it. (The International Space Station is very striking,
if it passes within view.) Record and report the object you observed,
the time and date of observation, the weather conditions at the time
of observation, and the visual appearance of the object - both its brightness
and how it appears to move along the sky.
Extra Credit (5 Points): Follow one of the STARS &
OUR GALAXY links from the main class web page (under Material to
Help You out). Explore some of the sublinks, and write a paragraph
summarizing what you find, and a paragraph describing what you learned
(Use your own words!)
Extra Credit (5 Points): Follow one of the
OTHER
GALAXIES links from the main class web page (under Material
to Help You out). Explore some of the sublinks, and write a paragraph
summarizing what you find, and a paragraph describing what you learned
(Use your own words!)
Homework #4 (25 Points) Due Tuesday Oct. 10

Unit 21, Problem 5; Unit 27, Problem 1; Unit 41, Problem 1;
Unit 45, Problem 2; Unit 56, Problem 3.
Note: this requires some planning
on your part, and many potentially observable satellites are not so easy to
see in the Metro area because of light pollution.
Homework #6 (25 Points) Due Tuesday Nov. 21
Unit 63, Problem 3; Unit 64, Problem 1; Unit 68, Problem 2;
Unit 70, Problem 3; Unit 72, Problem 3.
