NATURAL SCIENCES 104
LIFE ON EARTH
Professor Davis, Office Hrs MW 1:00,
Welcome to NATS 104 - Life on Earth!
In this course, you will learn about biological systems, from molecular to global.
You will gain first-hand knowledge about the processes of scientific investigation and communication.
You will gain a basic understanding of biological systems, how biological systems
are studied, how biological systems change, and how to understand and evaluate ongoing
progress in biology that effects your life.
- LEARN BIOLOGY! Attend all lectures and workshops on time, do all the readings
before lecture, hand in all assignments on time.
DON'T CHEAT! Your grade must reflect your understanding of biology.
Cheating defeats that requirement for yourself or for others.
Read the University of Arizona Code of Academic Conduct
and the University Code of Academic Integrity
Copying material from any other source is cheating. Although we encourage you to
study and work together, you must complete the work on your own.
What you hand in must be your own work, not handed in any other class by you
or anyone else. Your workshop paper must not be copied in any way from the internet
or any other source, it must be entirely your own words.
Cheating also includes giving your assignments to another
person to copy, because it causes that student's grade not to reflect their
understanding of biology. Cheating will result in a grade of zero for the assignment,
a failing grade in the course, and/or referral to the Dean of Students,
Melissa Vito firstname.lastname@example.org, and
Alexis Hernandez email@example.com
for possible suspension or expulsion from the University.
RESPECT: honorable and appropriate behavior.
Respect for students is shown through good manners, sympathy and impartiality.
The Professor and G.T.A.'s will be on time, prepared, and polite.
They will be flexible and sympathetic of the demands on students' lives as long as
accommodations do not violate impartiality, or prevent the learning of biology.
No favoritism should be shown. Students needing special
accommodations must register with Professor Davis in the first week of class.
Respect for the Professor and G.T.A.'s is shown in classroom manners: by showing up on time
for all classes and by not leaving early, by being quiet during class (all cell phones off),
and by following instructions.
Cheating is disrespectful to both the instructors and to fellow students.
CLASS WEB PAGE, AND READINGS
This course has a web page:
On this web page are IMPORTANT ANNOUNCEMENTS, lecture notes, supplemental material
for the lectures, the schedule of classes, policies (including this document),
and a lot more information that you will find useful for this class.
It is YOUR responsibility to check this web page frequently for
any new information.
You may communicate with any of us at any time by email
and we will get back to you as soon as possible.
We strongly encourage you to use this avenue to ask for clarification about the course material,
make appointments, or for any other reason relating to class.
The online schedule of classes
outlines the topics that we will cover in lecture and in the workshops, and provides the reading assignments from
your textbook. The assigned readings should be completed before
Although we will not take attendance formally, you should anticipate
a lower grade if you miss classes - for the average student, about 1/5 letter
grade for every class you miss. The lecture notes are posted on the class web page,
and the readings cover the material presented in lecture, but neither gives
the emphasis and explanation provided in the lecture. You are responsible for
all of the content of the lectures, including material not in the readings. By missing
lectures, you will miss any corrections and explanations that are made in class.
If you will miss a lecture or workshop - for any reason - you MUST
notify us BEFORE class or workshop by email or phone message. It is YOUR
responsibility to keep us informed. If you fail to notify us before class or workshop,
you will not be eligible for make-up lecture exams. Read
Make-up Materials: all workshop/homework assignments and term paper are due
on the day specified on the class schedule and will
be assessed a 10% per day late penalty unless (1) the student has contacted the T.A.
in advance and (2) the student has a valid excuse related to health
or academic conflicts. There are no make-ups for quizzes. Only one
lecture-exam make-up will be given for all the students missing the original exam,
and then only if (1) the student has contacted Prof. Davis in advance and
(2) the student has a valid excuse related to health or academic conflicts.
There will be no other option to receive credit for that exam. Due to its date at
the end of the semester, there is no make-up for the third lecture exam.
Tardiness: No lecture exams will be handed out after the first person
to finish the exam has handed in their exam. No workshop quizzes will be handed
out five minutes after the quiz has begun.
Our goal is to give grades that indicate how much biology you have learned.
The level and amount of material has been selected so that an average student
can get a "C" if they do an average amount of work, and an "A" if
they work hard: spend 9 hrs/week outside class reading and reviewing,
read assigned material before class and workshop, review the notes
before and after class, miss no classes, be on time, hand assignments
in on time, do all the extra-credit assignments, attend and participate
in review sessions. Students who already know the material covered
in NATS 104 should contact Prof. Davis, regarding testing-out of the
There will be NO CURVE, the grades will be awarded strictly on the basis of
the percentages given in the table above. See the statements on cheating
elsewhere in this syllabus.
Note that there are policies with implications for your grade in other sections
in this syllabus. Here we explain procedures and policies for this class.
Please read the following material carefully.
Our emphasis is on learning, not on testing. The exams and quizzes are a
means to an end, not the goal itself. The purpose of the exams is to evaluate each student's
understanding of all material presented in NATS 104, not to reward students for
memorizing a small part of this material. Our philosophy is that all of the material
is important, not just one or two figures or tables; this important material includes
the assigned readings, the lectures and the workshop/homeworks. Each of the three lecture
exams will include 20 - 50 questions, for a total of 100 points on each exam.
Make-up exams will have different questions and be of a different format (essay & short answer).
During the exam period, no exam will be handed out after the first student to finish
the exam has handed in their exam. The third exam is scheduled for one hour during the final
exam time scheduled by the registrar for this class. It is not a comprehensive exam,
it covers the material in the last third of the course. There is no make-up for the third
Un-announced ten-point quizzes will be given at various times during several lectures or
workshops. The purpose of the quiz is to evaluate students' understanding of the material,
assigned readings, or the workshop.
There will be a total of at least 6 quizzes, and your grade will be based on your 5 highest scores.
There are NO make-up quizzes. If you miss a quiz FOR ANY REASON, including
illness, sporting events, family emergencies, etc., your grade will be based on the best
All students in NATS 104 must attend lectures on MW 2:00-2:50, and the workshop/homework
sessions on Friday. Some of us find it easier to learn by doing, and the workshop/homework exercises
provide an opportunity to learn in a "hands-on" way the major themes of NATS 104, and to expand on
them. The workshops offer exposure to the scientific process, including research methods,
analysis and compilation of data, library research, scientific debate, and the writing of
research reports and papers. Your workshop exercises are worth a total of 120 points. They
must be handed in on time to receive full credit. [expectations]
