An additional general reference is

SEDS

Prepare for an observing session with their catalog of Messier objects at http://www.seds.org/messier/

 

Heavens above provides a good site for much of what we observe, including Comet Linear and the International Space Station.

Eclipse photographs can be obtained from The NASA/GSFC Eclipse Home page and from

a. Course Description (Note that availability of observations is dependent upon season and weather - other observations will be substituted if indicated planets, nebulae, etc. are not currently visible)

280. Workshop in Astronomy 3 s.h.

The sky around us; early history; the Copernican revolution; the solar system; the sun and stars; star clusters, nebulae and galaxies; the big bang and aftereffects; life in the universe. Intended for elementary, middle school and secondary school teachers. Prerequisite: a methods course in the teaching of science or permission of the instructor.

b. Goals and objectives

The goals of this course are

(1) to make K-12 teachers sufficiently literate in Astronomy to use topics from astronomy in their classrooms,

(2) to make them familiar with scientific reasoning, including the evolution of scientific theories (e.g., Hubble's law and the big bang) and the role of experimental verification, and

(3) to demonstrate the coevolution of scientific theories (e.g., the heliocentric theory)and scientific instruments (e.g., the telescope).

 

c. Typical assignments

Observations, recorded in a laboratory notebook

(1) Bright objects in the sky: the sun, moon, Mercury, Venus, Mars, Jupiter, Saturn (in general two of these planets should be observable), stars and constellations, apparent motion of the stars*

(2) Evolution of the telescope - what we can see with the naked eye, with binoculars (which are only a little weaker than Galileo's telescope)*, with small telescopes

(3) Jupiter's four largest satellites (using binoculars and telescopes)*

(4) Star clusters (using binoculars and telescopes)*

(5) The Orion nebula (using binoculars, telescopes and CCD cameras)*

Laboratory recorded in a laboratory notebook

(1) Calculation of the diameter of the earth; measurement of the diameter of the moon from lunar eclipse photographs and the diameter of the earth*

(2) Measurement of size of lunar craters

(3) Eclipses

(4) Observing the sun: precautions, pinhole projection*, sunspots, H-alpha view of the solar corona; multispectral observations from spaceweather.com

(5) Power output of the sun*

Exercises:

(1) Making a planisphere*

(2) Computer-spreadsheet exercise: Kepler's laws

(3) Computer exercise on Hubble's law (from the CLEA project). This exercise has the students run a simulated spectrometer and rediscover Hubble's law.

(4) Constructing a web interface for your school

Papers

(1) Select one of the following topics and write a 500 word essay, including bibliography.

(a) Evolution of the telescope

(b) How we verify a scientific theory

(2) Select a recent discovery in astronomy (for example, the discovery of wandering planet-like objects) from a journal such as Nature or an astronomy publication such as Sky, and write a 500 word summary of the discovery and its significance. Additional references beyond the selected article are needed.

 

Final exam

*: exercise can be adapted to public schools
