Method of Evaluation: You are not obliged to write a term paper or to do four of the six on-line study quizzes, but you must do one or the other to count for 50% toward the term-work component of the final grade. You may use only one choice or the other for the 50% term-work grade. For most people, the quizzes have given the better raw mark but as we adjust the marks of the term-papers to the same average as attained by the cohort of quiz grades, there should be no disadvantage in writing a paper. Still, even if you write a paper, you should do the quizzes as they help you focus on the expectations of the course as they will be tested on the final exam.

If you choose to submit a term paper (with text body less than 1000-words) in a formal scientific article style with proper referencing of sources, it will be due on March 30, 2021. TAs will be available to help you with your term papers. Papers are to be submitted on-line in either *.doc, *.docx or, preferred, in *.pdf formats. The e-mail address for submission: terrestrial.planets@gmail.com . Late papers will be penalized at 10% (i.e. 4 marks/week or 0.5 marks/day). If you do submit a term paper, it is that paper that will count for 50% of your grade, but if your quiz grades are higher, we shall accept the quiz grade for term work.
There will be 6 on-line “Study Quizzes” offered, a new one given every second week during term; your best 4 will count. Moreover, there is a practice quiz posted on the myCourses site for you to try a few times and to help you become familiar with the method for accessing and submitting quizzes. This practice quiz will be left available for your continuing practice throughout the term. The first of the Study Quizzes (Quiz #1) to be counted will be posted on Friday, January 22 at 00:00AM for completion by midnight that day. You will be free to do that quiz twice and the best of your 2 grades will be recorded for Quiz #1.
For the following quizzes, you are given only one try. Thereafter, new quizzes will be posted every second Friday morning. These quizzes will be open on Feb. 5, Feb. 19, Mar. 12, Mar. 26 and Apr. 16 at 00:h00, Montreal local time. The last ( April 16 ) of these serves as a whole-course tutorial review that may be used as a study aid for the final exam; it will remain open and available through until the morning of the day of the final exam. You might wait to do it until a day or two before the final exam when you have already done some exam preparation.
You should try to review your notes before attempting the online quizzes because they are time limited. You will normally have only 15 minutes for each study quiz excepting the overrun/grace time extension which allows you a total of 35 minutes of quiz time. Students with disabilities who can present a note from OSD to that effect will be given additional time as required by OSD. You must inform me with a letter from OSD or ask the OSD office to e-mail me to effect your access to these quizzes. If you can't follow this schedule for the online quizzes, you must write the term paper (due on March 30) for the term work's 50%. You can no longer, under current Faculty of Science rules, write the final exam for 100% of your grade.
If you choose not to write the term paper in favour of the study quizzes, the best 4 will contribute 50% to your final grade. Each on-line study quiz will require you to be computer-connected to the myCourses website, best through a McGill wireless or LAN connection or via McGill VPN, during a period of 15 minutes, anytime, within the 24-hour time window which starts the Friday morning at 0h00, remaining open until midnight that day. You need only log-on within that accessibility window to access your 15-minute quiz. The Faculty requires time extension so you should have at least 35 minutes to complete the 15-minute quiz. Each quiz will comprise 30 multiple-choice, true-false or ordering questions. You should try the practice quiz a few times in order to learn how to use the system. Note: An online quiz will not be re-opened for those who miss a quiz during the 24-hour time windows for any reason at all (including severe illness, dogs that have eaten your computer – anything!). There are, however, 6 opportunities to take quizzes and you only need 4 completed for a full term-work grade. If you have continuing technical problems while trying to do the online quizzes, submit a term paper instead on March 30; it will be preferentially counted toward the term work. Use the practice quiz as often as you like in familiarizing yourself with the procedures.
Final exam will be served online and scheduled. The final exam contributes 50% to your final grade. Note , you can no-longer write a final exam for 100% of your grade: Do the quizzes or write a term paper! You must write the final exam to receive a grade in the course. If you know that you cannot sit the exam, you should withdraw from the course now.
This year's online final format: The format of the final exam is not yet set. The form will depend on whether or not the Faculty of Science will allow for a 2-hour exam in 48-hour availability window. They may require a 3-hour exam with a 72-hour availability window. Whatever the Faculty's requirements are, the exam will use multiple-choice, true-false and matching questions mixed, with either 10 or 15 written response questions according to the exam length. As exams have an extended time limit (4.5 for a 2-hour exam and 6.5 for a 3-hour exam) you should have lots of time to complete the final. It should be easily possible to complete the exam in the prescribed 2 or 3 hours and it may be open to your for 48 or 72 hours.
On final grading... Class average final grades during past years have fallen into a range of high B to low B+, about 75%. In order to achieve this average, grades may be fairly curved but only upward if necessary. Given the online format and the extended time allowed according to McGill rules for online exams, it is not expected that any upgrading will be necessary. The course expectations are not extremely high in the sense that this course traditionally offers somewhat higher average grades than many in-program courses. However, the grading is strict, fixed and absolutely non-negotiable. Typically, in past years, more than 25% of students have received a full A grade and another 20% an A- grade. Almost nobody fails the course if they do the required tasks – term paper or 4 study quizzes + final -- though several students have managed to get D grades. Note that a D grade obtains a Fail if the course is taken Pass/Fail; it is not a technical failure if not. In 2018, 72 of 155 students who completed the course received A or A- grades. Last year with the much extended times offered for online exams, exceptionally, about 75% of students received A or A- grades.

Students who can and who fear for their grade are encouraged to consider taking the course on a Pass/Fail basis if their program so permits. You should note, however, that a D grade according to the normal grading scheme would qualify as a Fail on the Pass/Fail basis. In defense against a D-Fail, you should note on your final exam that you are taking the course Pass/Fail if you are.

You normally have to register for the course as being Pass/Fail before the Add/Drop deadline late in January but this past year, you could opt for the Pass/Fail option after receiving your course grade.

Textbooks... No textbook is required for the successful completion of this course. The course Noteset suffices but, should you be interested in having a good reference for the course, I suggest, first of all, The Cosmic Perspective (Bennett et al.). Alternatively, you might consider The Solar System (Seeds and Blackman)

While the information about the Universe, Solar System and Planets is continually being updated, used earlier editions of these texts are still useful references for the course. Neither is “required”. The Online editions may well serve you.
Help/Questions regarding course -- “on-line office hours”:
Office hoursare on-line. I can usually respond to your questions within a day. Please use the following address for course-related e-mail as this will separate course e-mail from my normal clutter: terrestrial.planets@gmail.com

The Lecture Series


First lecture (January 7 online): Course outline, introduction of self and screening of short videos:

1. Harvard Commencementa film that should bring you to feel that you are already as knowledgeable about seasons as Harvard graduates: A private universe. An explanation of seasons and Earth's orbit. More: Do you know that the shortest day of the year does not include both the latest sunrise and earliest sunset? The cycles of the Sun and Moon. Do you know how to tell time and read a calendar? Also here! This interesting (and correct) video was produced by the Vsauce guys.

2. Cosmic Collisions a NASA/AMNH film. I usually play an authorized copy of this video at the start of class but this year, I cannot offer you an online version. Otherwise, you might look for this video on the web... but note, several different videos with this title are published on YouTube; they are mostly interesting and relevant but I have not been able to find this particular video in the group. This is the trailer to the AMNH film and the only reference I could find on YouTube.

3. As today's lecture concludes, I suggent you start the video entitled Different Worlds (BBC series The Planets) in class; BBC sometimes pulls this video from all the internet sites that I can find. As of the beginning of this course, it is accessible.

4. For home, a mystical ride through the Universe: The known universe by AMNH.

January 12 to April 13 (25 classes): (Note, the order is followed -- it is the same ordering as in the course noteset -- but each listed topic does not correspond to a single or whole lecture.)

  • Creation hypotheses, the age of Earth (and the Solar System)

  • Suggested online videos: The Big Bang to the Present Day, The Big Bang , The Expanding Universe on YouTube. The concept of distance is complicated: see Faster Than The Speed Of Light (1): The Universe - Created Out Of Nothing? and Faster Than The Speed Of Light (2): The Expanding Universe on YouTube for an attempt at an explanation of the “origin, age and sizeof the Universe. You might look into the Cassiopea Project (on-line Science education) which served the first video in the list preceding.

  • How do we “ know” the “ age of the Universe? Hubble constant and age of the Universe

  • Stellar evolution – A cute cartoon: The Largest Stars; Stephensen 2-18

  • The condensation of the solar nebula – formation of the Solar System. Suggested online video: The Expanding Universe (The Planets) in 6 parts on YouTube; you may access them now with search string [ 1of6 The expanding universe the planets ] Some of this video is dated in its information... (e.g. a 12 billion year age for the Universe) but for the most part, the story holds.

  • Early thermal evolution and differentiation of Earth and the terrestrial planets

  • The present Solar System (a quick tour of the planetary system); Exoplanets.

  • Asteroids, comets, meteorites and the recently discovered and now visited Kuiper objects

  • Hazards – cometary and asteroid impacts on Earth

  • Orbital dynamics – Kepler's Laws

  • Study week March 1-5 lectures cancelled

  • Most of the Universe is Missing – A BBC Video (Is Newtonian gravity the problem or is there a lot of unseen dark matter?). A precis of the transcript of this BBC Horizon program is linked here . This video will be shown in its entirety in class.

  • Dynamics of the solar-planetary system: orbits, rotations, spin-orbit coupling. The moon, tides (body and ocean) and the history of Earth's rotation

  • Rotational dynamics, precession, nutation and wobble

  • Physical properties of the terrestrial planets: isostasy, gravity field, density distribution, thermal regime, etc.

  • Planetary magnetism: evidence for a fluid core and the self-excited geodynamo

  • Tectonics, the effect of heat flow, thermal conduction and convection on Earth and other planets and moons

  • Seismology and the structure of Earth's interior, the Moon's interior, Mars interior?

  • Overview of the geological and geophysical differences among the terrestrial planets

  • A review tour of the planets and moons of the Solar System and beyond.

  • Current space missions – a review of what is happening now.... a web tour and discussion...

  • Astrogeology, mineralogy and surface condition of the terrestrial planets and moons of the giants. What can we infer about the interiors of the hard-surfaced bodies of the Solar System from surface features... The search for life elsewhere in the Solar System

  • Finishing on April 15(?) with another video: Video 2 of The Planets Series – Terra Firma (BBC/A&E) If still available online this video should be a useful overview preceding the final exam...

  • The final exam: Not yet scheduled – I have no influence whatever on the scheduling.
