INDEPENDENT HOMEWORK, IN GENERAL Independent homework assignments (IH) are enrichment assignments. So, enjoy yourself! They are not supposed to feel like homework, and they do not directly contribute to the learning you do in Freshman Physics Honors class or in your daily homework. However, they do contribute to your awareness and enjoyment of physics. The IH assignments come in two kinds and you will do one of each kind each quarter – so two IH assignments each quarter. For the first kind (IH1, IH3, IH5, and IH7), you read books and/or magazine articles about physics. You get to choose the book or articles you want to read from a list of suggested readings, in the first, third and fourth quarters. However, in the second quarter , I choose the book and every student must read it. I do this because this particular book is important for every young woman to read and supports the Nerinx philosophy. For the second kind of IH assignment (IH2, IH4, IH6, and IH8) you have a wider selection of activities from which to choose. You certainly may choose a book or set of articles to read. However, you may instead attend a physics event, go to a science museum show, do a physics experiment, explore physics interactive websites, create something physics-y for the classroom, etc. There are many, many options. Tailor these IH assignments to your own interests. You get a lot of freedom in choosing exactly what you, as an individual, are going to do for your IH. Make choices that interest you and that are at the right level of difficulty and detail for you. Remember, these are enrichment activities. Use them to enrich your life. That said, if you find that in a given quarter you are struggling with the class content itself, then you may choose to use your IH not for enrichment, but to help you understand the course material. In that case you may to read books or go to websites that deal with the class content – instead of choosing an enrichment activity. SEE NEXT PAGE FOR PARTICULARS ABOUT IH1 AND IH2. p. 1 1 IH1 and IH2 – THE SOLAR SYSTEM AND THE UNIVERSE Your email for IH2 is due to Dr. Leopold: Wednesday, 9/16/15 Your email for IH1 is due to Dr. Leopold: Friday, 10/16/15 In rare cases, with my permission, a student may turn in IH2 on this second due date, along with IH1. You must ask me well ahead of time and get my permission in order to do this. You may turn in either IH early, when you have it finished. You do not have to wait until the due date written above. To receive credit for an IH, you must send me an email (mleopold@nerinxhs.org). The subject line of your email to me must be: Your class block one space your last name one space which IH it is Here is an example of a correct subject line, for a student named Maddie Veltz, in H block, who is turning in IH1: H Veltz IH1 SEE PAGE 3 FOR INFORMATION ON IH1. SEE PAGE 8 FOR INFORMATION ON IH2. 2 IH1 – 20 points Read books and/or magazines about astronomy. You may use books and magazines from home, from the Nerinx library or from your local county or city library. If you have access to a college or university library, you may also use books from there. (You must read something new, of course; you cannot just use a book you read last year or for another Nerinx course.) You may read books and magazines at any level – this includes books for young children all the way up to books for adults. Whatever you would enjoy the most. You must spend at least 120 minutes reading. (Usually this will not be enough time for you to finish a book. That’s OK.) You should not be taking any text messages or emails, or watching TV, or have any other distractions during this reading time. You may break the reading time into, at most, 8 sessions, with each session being at least 30 minutes long. In other words, you have to concentrate and focus on your reading. In the email for IH1 you must tell me: 1. What you did and exactly how long you spent (to the nearest minute – so keep track). If you read a book you must tell the title and author and which pages in the book you read. If you read parts of several books, you must do this for each book. If you read magazine articles you must tell the name of the article, the pages you read, the volume of the magazine (June 2014, for example) and the name of the magazine. If you read several articles, you must do this for each one. For reading assignments, you have to read books and magazines – you cannot read things on the web, even if you print them first. 2. Who you told about your reading. Try to tell someone! 3. Which readings were fun/interesting enough that you would recommend them to other freshmen, and why. 4. One new thing you learned about astronomy, that seems so interesting you think you will remember it for a long time. (Don’t say, “I learned more about galaxies.” Tell me specifically what you learned, so I can learn it from you!) Your answers must be in complete sentences. The questions must be numbered as shown above. The length of your email should be in the range 120 - 170 words.

Mrs. Winkler found this: http://www.youtube.com/embed/XRCIzZHpFtY?rel=0 It is a short video showing how we send a rover to Mars. Some of it seems to be real video, but some of it I THINK might be animation – I just can’t tell. I went to the NASA site and I see some of this same footage, so I think we can believe that this video is correct. 15 ASTRONOMY WEB SITES Astronomy Crash Course – 28 separate videos you can watch in order, or just choose one or two on your favorite topics. Each video is under 20 minutes long. Kerbal Space Program – a game in which you explore a solar system The St. Louis Astronomical society web site This has talks you can attend once a month, telescope viewings you can attend and many reference to other interesting web sites Adoptaphysicist This begins in October. You can’t work on this until then. I try to sign us up for 3 different astronomers/astrophysicists. You first read a couple of paragraphs about each person. Then choose one whose work you are interested in. Then you begin an email conversation with him or her. You may ask questions about his or her work day, his or her preparation for career, the physics he or she has to know, etc. Learn about the planets, recommended by Abby Host A websites that show the relative sizes of all things, starting from the smallest and going to the largest; there are 2 different looking web addresses that take you to the same thing https://www.youtube.com/playlist?list=PL8dPuuaLjXtPAJr1ysd5yGIyiSFuh0mIL https://kerbalspaceprogram.com/en/?page_id=7 http://www.slasonline.org http://www.adoptaphysicist.org http://nineplanets.org/jupiter.html. http://www.primaxstudio.com/stuff/scale_of_universe/scale-of-universe-v1.swf http://scaleofuniverse.com http://www.numbersleuth.org/universe/ A few of the very best of the many photos taken by the Hubble Space Telescope. http://www.google.com/earth/explore/showcase/hubble20th.html#tab=ngc-6302 Astronomy picture of the day http://apod.nasa.gov/apod/ap070817.html Women who work for NASA http://women.nasa.gov Website of the mission that is looking for planets around other stars that could support life. http://kepler.nasa.gov/ 16 lectures on many topics – choose ones on astronomy topics of http://www.learner.org/resources/series42.html?pop=yes&pid=560 interest to you Khan Academy - short lecture videos – choose ones on astronomy topics of interest to you http://www.enchantedlearning.com/subjects/astronomy/solarsystem/index.shtml “Origins of the Solar System” (13 minutes long) The Hubble telescope site http://hubblesite.org/explore_astronomy/black_holes/ Gameshttp://spaceplace.nasa.gov/solar-system-explorer/en/# http://www.thecrimson.com/article/1980/1/7/exploring-the-invisible-astronomyin-the/ —http://www.planetfacts.net/ —http://www.moonconnection.com/moon_phases.phtml —http://library.thinkquest.org/J002231F/Sun/factsaboutthesun.htm —http://solarsystem.nasa.gov/planets/profile.cfm?Object=Sun -http://science.nationalgeographic.com/science/space/universe/black-holes-article/ -http://www.universetoday.com/46687/black-hole-facts/ -http://physics.about.com/od/astronomy/f/BlackHole.htm -http://imagine.gsfc.nasa.gov/docs/science/know_l2/black_holes.html -http://www.kidsastronomy.com/black_hole.htm -http://hubblesite.org/explore_astronomy/black_holes/home.html Astronomy Word Puzzle; Astronomy Hangman; Astronomy Quiz. http://www.kidsastronomy.com/fun/ 17 Space and Astronomy Quiz; Space Word Scrabble; Earth, Moon, and Sun games. http://www.sciencekids.co.nz/astronomy.html 1. http://www.webexhibits.org/calendars/moon.html?day=31&month=8&year=2012. http://www.thecrimson.com/article/1980/1/7/exploring-the-invisible-astronomyin-the/ http://www.hq.nasa.gov/alsj/a11/Apollo11_Press-Kit_restored.pdf 18 ASTRONOMY PROJECTS Make a balloon rocket This is easy and quick. http://www.slsc.org/balloon-rockets Make a large 1D scale model of the distances of the planets from the Sun Use a long rope and make knots or tie ribbons where each planet is. Then get students to “be the planets” – hold the rope at those spots – and take a look at how far apart the planets are. Make it BIG – as in the size of a football field – or even bigger! If you need help with the calculations, just ask me. We will hang these from the ceiling in the classroom. Figure out how to do that – maybe your art teacher has an idea. Have a string or something coming out of the top of each planet for hanging. If you need help with the calculations, just ask me. Same as above. If you need help with the calculations, just ask me. Be sure to include first homo sapiens in 50,000 BC, and big bang 13.7 billion years ago. Make it so it fits on, and can be displayed on, the Science Bulletin board in the west hall. Or make it on a rope, that we kind wind up and put in a drawer. Use http://www.seasky.org/celestial-objects/nebulae.html to help you do this. Your poster must be small enough to fit on ONE cabinet door in N3 Your poster must be small enough to fit on ONE cabinet door in N3 Make a 3D, scale model of all the planet sizes. Make a 3D, scale model of the sun and the earth Make a time line of the history of the universe Make a poster about the five different types of nebulae Make a poster about some other aspect of astronomy Get a telescope kit and build yourself a telescope View the night sky View the night sky View the night sky View the night sky. Lie on your back on the ground outside and look at the stars. What do you see? If you can, get out into farm country to do this, away from light pollution. The best is to try this once at home and then once out in the country, and to compare the difference. Use binoculars to view the night. Compare looking at a star to looking at a planet, both with binoculars and without them. If you have a telescope, use it! Go out in the night and look at the Moon. Find out what planets are visible and take a look at them. What features can you see? If you have a smart phone, download an app called SkEye. Then lie out in your yard looking up at the sky and use the app to identify constellations, stars and planets. 19 RESEARCH TOPICS: ASK YOURSELF AN INTERESTING QUESTION AND TRY TO FIND THE ANSWER IN BOOKS, MAGAZINES AND ON THE INTERNET. Where did the names of the days of the week come from? Kaitlyn Reynolds recommends this. What different calendars are there now, and how were they devised? Look into the inner planets in detail. How are they similar? How are they different? Look into the outer planets in detail. How are they similar? How are they different? Who was Copernicus and what did he do that was so interesting? Who was Galileo and what did he do that was so interesting? Who was Newton and what did he do that was so interesting? Who is Vera Rubin and what did she do that is so interesting? 20
