NATS 1740B: ASTRONOMY (Fall-Winter 2020-21)

FINAL EXAM: FORMAT AND EXPECTATIONS
When and Where:
• Tuesday, April 20th, 2-5pm (‘Toronto Time’) (3 hours)

• In eClass, go to the new FINAL EXAM section at the top of the course home page. At the start of the exam, you
will see two items:
o ‘Final Exam – Articles and Instructions’ file, revealing the 3 articles to be used for this exam.
o ‘Final Exam – Submission of Answers’ link, opening a TurnItIn assignment submission link for you to
submit your typed responses into, within the exam time window above.

• Make sure you have the necessary technology (computer with stable internet connection) available exactly
when you need it for this exam.

• Late penalty policy: any exams submitted after the 5pm deadline will be deducted a late penalty of 5% for every
10 minutes past the deadline, within the first hour after the deadline; no further exams will be accepted after 1
hour past the original ending time.
Exam Format and Settings:
• This exam is based on Lessons 13-23, and all connection points should be made to concepts explicitly covered in
these lessons.

• You will be presented with 3 (three) different media science news articles to read, each with a suitable word
count range (around 1,000 words approximately, to maximize content opportunities for making multiple
connection points to our lessons), from sources such as www.ScienceDaily.com and https://phys.org/space-
news/, published outside of our research project’s period in the current semester(s).

• For each article, you will then complete a typed response (in a Word file on your own computer) containing:

o 3 (three) connection points between the article and our lesson materials (lesson notes/slides and/or
readings, over single or multiple different lessons covered this term). Each connection point should:

▪ Have a clear title given for the connection point, including the general scientific concept being
connected between the article and the lesson (eg: life stages of stars), and a specific reference
to the lesson materials (eg: lesson 17, section 7.4 The Birth of Stars in the textbook/ebook)

▪ Be written fully in your own words! Copying sentences, in part or in full, from the articles
themselves and/or lesson materials constitutes plagiarism, as does copying/sharing answers
between classmates; this in turn may result in deductions ranging in severity. Using other aides
like Google Translator is highly discouraged, as it can lead to copied material being selected
from the web, and resulting in plagiarized content submitted by the student. Instead, after
reading each article and identifying the scientific concepts for your connections, try putting the
articles away and writing your connection points completely on your own, with proper English
grammar and writing style.

▪ Demonstrate meaningful insight into the scientific material presented in the article and
covered in the lessons, by explaining clearly how your stated scientific concept in the connection
point – as first explained in our lesson materials – is now also being investigated in the scientific
research being reported in the assigned news article. Compare-and-contrast type analysis is a
good technique to use here, by first comparing the similarities in the scientific concept (between
the lesson materials and news article), and then contrasting any possible differences between
them as well, such as new or unexpected or contradicting results discovered in the research
compared to the previous knowledge on that topic (as covered in the lessons). Make sure there
is adequate discussion of both the news article and textbook readings/lessons in each
connection point.

▪ Be between 50-150 words long as a general guide. (Higher grades will be assigned for higher
quality of connection points presented, and not simply for meeting the minimum word count.)

• Once you have completed all your responses, with 9 connection points to lesson materials created in total, you
will then submit the Word file to the TurnItIn submission link.

• All students will be expected to maintain full academic integrity in the exam by composing their own original
responses, which will in turn be reviewed for any possible plagiarism by the TurnItIn software (for example).
Although all students will be reading and responding to the same articles, their responses to them should still
nonetheless be individual and unique, just as they would be at an invigilated, paper-based exam on campus.
Each student is also expected to complete this exam individually and by themselves. The Senate Policy on
Academic Honesty is an affirmation and clarification for members of the University of the general obligation to
maintain the highest standards of academic honesty. Any instances of plagiarism and/or other breaches of
academic honesty policy may be subject to further investigation and possible consequences as outlined in this
policy.

Example of a Connection Point
Article: Radioactive elements may be crucial to the habitability of rocky planets
https://www.sciencedaily.com/releases/2020/11/201110151156.htm

Connection Point 1: Internal heat of Earth; Lesson 12; Chapter 13.1 A Travel Guide to the Terrestrial Planets
Both the news article and the textbook section 13.1 discuss internal heat of Earth as being a crucial factor in determining
our planet’s physical characteristics and geological processes like plate tectonics and the magnetic field, which in turn
help make our planet the habitable world that it is. The amount of internal heat in Earth, and how it makes its way out
of from the dense hot inner core to the cooler less dense surface regions of Earth, is emphasized in textbook Section
13.1, sub-heading ‘Core, Mantle, and Crust’. Earth’s amount of heat and escape route creates ‘just right’ temperatures
and type of mantle materials for plate tectonics to be able to work on our surface, as discussed in Section 13.2, sub-
heading ‘Earth’s Interior’. By contrast, as reported in the new modeling research in the news article, different amounts
of internal heat in other planets could lead to impaired processes of this heat escaping, and in turn affecting the creation
of proper magnetic field and plate tectonics.

Other possible topics for connection points in this article (related to other sections in textbook as well):
• focusing more specifically on how too much heat from too many radioactive elements can shut down the
geodynamo effect, thus ruining the magnetic field

• importance of a magnetic field to protecting the planet’s atmosphere
