Astronomy p/4 (Period 4) Assignments

Here are our latest presentations on EM radiation: electromagnetic frequencies; Wien's Law and Blackbodies (prezis each), and our PPt on the Doppler Shift.

Happy Holidays, campers! We have two weeks apart, but we still need to get through the first half of Chapter 3, "Light and Atoms."

If you have not done so, please read Chapter 3, Section 3.1, "Properties of Light," pp 92-96. Answer "Questions for Review," p 116, #1-3 and post the answers on edmodo (if you haven't handed them in on paper by Friday.)

New:

READ Sections 3.2 "The Electromagnetic Spectrum: Beyond Visible Light", pp pp 96-101; 3.3, "Atoms," pp 101-104; and 3.4, "The Origin of Light," pp 104-105

ANSWER Rev. Questions p 116, #4, 5, 8, and 9.
Also, ANSWER these questions:

1. How did Sir William Herschel show that heat from the Sun is related to visible light?

2. How do infrared and ultraviolet radiation differ from visible light?

3. What is the range of radio waves?

4. Why are microwaves and gamma waves so difficult to study from the earth's surface?

5. List, in order from LEAST energy to GREATEST energy generated, the types of EM (electromagnetic) radiation.

6. List, in order from shortest wavelength to longest wavelength, the types of EM radiation.

7. HOW are the answers for questions #4 & #5 related?

8. A burner on an electric stove, as it heats up, glows dull red at first but after five minutes glows a bright yellow. How does the color of the burner relate to the temperature of the burner?

9. What is Wein's Law?

10. What is a blackbody? Why are blackbodies excellent absorbers AND emitters of energy?

11. Describe the parts and structure of an atom.

12. How are electrons similar to planets in a solar system? How are they different?

13. What is an element? How is the identity of an element determined?

14. How are electrons bound to their nucleus?

15. What is happening to an electron in when its atom is "excited?" What is happening to the atom's energy?

16. What is the Law of Conservation of Energy? Thinking of this law, what must happen when an atom loses energy?

17. What is emission?

18. What is absorption?

READ Chapter 3 "Light and Atoms" Section 3.1 Properties of Light, pp 92-96.
ANSWER Review Questions, p 116, #1-3 on edmodo.com.

READ the article provided to you in class - "What is Spectroscopy?"
WRITE Cornell Notes on the article - to turn in on paper (unless you have discussed this with me beforehand).
ANSWER the 10 questions given to in class on the article. You may post in edmodo OR turn them in on paper.

Period 4's edmodo.com's code is lb5ary

1. Your prezi on your favorite Law of Motion is due on edmodo.com tomorrow by midnight!

2. Your in-class demo/s for all three Laws of Motion will be performed in class tomorrow.

If you have not yet done so, please put together your unscored dailies - up to and including 12/6/12 - and turn them in tomorrow.

(11) Complete the Math Practice worksheet for Newton's Second Law (acceleration) that you began in class.

(12) "WS - Mr. Newton and his Laws of Motion" is due.

(10) Newton's Laws of Motion Key Terms Practice worksheet pkt (3 pages)

YOU ARE HAVING A TEST TOMORROW!!!!

Chapter 1, sections 1.2 & 1.3.

You will be tested on the contributions of the historical astronomers (the Greeks plus Ptolemy), Copernicus, Kepler and Galileo. NO math. NO temperature conversion. NO Newton or Laws of Motion.

KNOW why the painted walls of the Cave of Lascaux (in southwest France) and Stonehenge are notable to astronomy.

KNOW Kepler's Three Laws of Planetary Motion.

KNOW the difference between geocentricism and heliocentricism. (Which is reality?)

KNOW what Occam's Law is.

We have begun Chapter 2, "Gravity and Motion," starting off with a brief history of Newton and more time spent on his three laws of motion: inertia, acceleration, and action/reaction.

Your foldable for the three laws of motion is due tomorrow if you did not complete it today.

Please read pp 76-79, through 2.3 "Orbital Motion and Gravity." IN EDMODO, answer this thought question: Which do you think has more inertia: a small, inflated balloon or a cinder block? If each were moving toward you at 1 meter/second, which would be easier to catch?

Here is the pdf/PPt for temperature that we went over today. Your conversion work sheets are available in the classroom, and because of the fire drill in period 2 today, we will take tomorrow, 11/20/12, to do them in class.

(4) on your assignment sheet is the Worksheet of Kepler's Laws and Planetary Motion.


Here is help for Problem #6, which deals with Kepler's 3rd Law of Harmony:

(Period of Orbit)^2 = (Average Distance from the Sun)^3

The pdf of this worksheet is attached. Read pp 49-52 of your text as well as your class notes to refresh yourself about Kepler's Laws. #7 is Extra Credit, and you do not have to do #8.

Also, attached is our latest prezi about Galileo Galilei.

Here is our latest prezi on Galileo and his contributions to astronomy.

Here are our latest prezis: on Copernicus, Brahe and Kepler.

If you haven't done so already, please go to edmodo.com, create a student account and join our period 4 astronomy class, code = lb5ary.

Also post the name of your assigned astronomer ASAP!

Sorry, guys - I thought I had put these prezis up on the website last Thursday. Here they are.

ALSO - for homework:

Read pp 20-40 of the textbook
Answer p 57, #1-10

NOTE - I am collecting this assignment; it does NOT go onto your stamp sheet.

Here is the prezi link for our first prezi of this chapter - History of Astronomy

Here is a link to the online video for archeo-astronomy and the caves of Lascaux.

You will be asked to write a short discussion of your impressions of the video, the French researcher and her conclusions at the end of the video, so take notes! 8-)

Let's turn in your "Backyard Astronomy" stamp sheet and all stamped work on Wednesday!
