Chandra X-Ray Observatory Internet Scavenger Hunt

Save this file to your own folder (the one with your name on it). If you can't save it, open it then copy and paste the whole thing into a brand new Word document, then save that in your own folder. Use a descriptive but unique filename with no spaces. Then type your answers directly into your document, and I will open it and grade it directly from your folder.

Believe it or not, this is a real image taken by NASA's Cassini space mission.

What makes a good wiki?
According to Mr. D's astronomy students, a good wiki should meet the following criteria:
•attracts and holds attention (catchy title, interesting "hook")
•accurate, current, up-to-date information
•information is detailed, thorough, specific, and meets goals of project (not too little, but not too much)
•accurate spellling
•accurate grammar
•good use of images (relate to topic, well captioned and cited, appropriate number [not too many, not too few], appropriate size, clear and easy to see)
•detailed, specific, thorough information original, unique (not plagiarized or "copied and pasted") “plagiarism is weak”, "None of this copy and paste stuff."
•attractive, eye-catching, "professional" appearance (bright colors, interesting fonts)
•creativity (funny, interesting, entertaining, uniqueness, "not boring")
•all information properly cited as demonstrated on the IRC page (sources named, links provided when possible)
•font style and size easy to read (not too big, not too small)
•well organized in a logical order (outlined with sections and headings, titles/subtitles and/or bullets, not bunched together, not "squishing and convoluting")
•makes audience want more
•concise, to the point, not too wordy ("quality, not quantity")
•shows evidence of good research
•incorporates editing and criticism
•appeals to multiple senses (images, sounds, movies/animations)
•page loads quickly

Kepler's Laws
This page features a reading, animation, and review questions about Kepler's Laws of Planetary Motion. Read the article, view the animation, take the "Guided Tour" of the animation, then write answers to 10 of the 17 questions on the "Worksheet." Each question is worth 5 points, for a total of 50 points. For full credit, please write your answers in complete sentences. Due on Friday, 10/20/06.
A great description and animation of retrograde motion. Follow each of the links to the left, in order. Write answers to all the exercises (on paper or on your own wikispace, like then grade your own answers using the solutions provided. Each exercise is worth 10 points, for a total of 40 points. For full credit, please write your answers in complete sentences. Due on Friday, 10/20/06.
Images and animation of Aristotle's and Ptolemy's models of the Solar System. Good explanation of "epicycles".
Another set of animations illustrating retrograde motion and comparisons between the Copernican and Aristotelian/Ptolemaic models of the Solar System.

Retrograde Motion of Jupiter and Saturn: "This photo animation of Jupiter (brighter) and Saturn (dimmer) clearly reveals their retrograde motion. Their observation began shortly after their conjunction in May of 2000 and continued for eleven months, as they passed through the constellation of Taurus. Two star clusters are also visible, the Pleiades (the dipper shape just above center) and they Hyades (the "lazy V" below and left of center)." and
