Classroom Procedures
Welcome to Earth Science! Earth Science is a high school – credit bearing course culminating with a Regents in June. The following is an outline of expectations, please discuss them with your parents / guardians, get them signed and return them
to your science teacher.
I. Homework
Homework will be assigned at least 2 days a week and is posted online. Homework is expected to be handed in on time and written neatly. (______________ = ____________ )~ it goes directly into the recycling bin. Homework is due the day after it was given unless otherwise stated.
II. Supplies
Everyday you must have with your notebook with paper (_____________________), pen or pencil, agenda book, and a ____________________. Coming to class prepared is part of your participation grade.
III. Textbook
Students must purchase a Review Book from _______________________ during the first month of school. (Approximately $13)
IV. Lateness
Lateness is disruptive to other students and will not be tolerated. You are expected to be in class on time and prepared.
V. Attendance and Absences
VI. Tests and Quizzes
Tests and quizzes are important for me to assess the comprehension of class material by the students. Major exams will be announced one week in advance. You should use this time to prepare for the exam and get any questions clarified. Frequently short quizzes will be given, both announced and unannounced. All tests and quizzes will be based on
______________________________________________________. By keeping up on these you will be prepared.
VII. Labs and Other Projects
Labs and other projects will provide hands on experience for all students. During the course we will be learning more about science by actually conducting experiments and doing hands on projects in a laboratory setting. Labs are designed to give you a better understanding of the material presented in class. New York State requires __________ of lab activity with a satisfactory lab report turned in for each. If you are absent for a lab activity, you have ONE week to make it up in extra help. (_______________________________________ – the lowest possible grade to count towards the Regents)
VIII. Cumulative Assessment
A cumulative assessment will be given at the ________________________ and is intended to evaluate student readiness to move on to the next level. This test will cover all material up to date and is intended to help prepare you for the REGENTS in June. Although this test is longer and has a lab component it will only count as one test grade.
IX. Grading
Unit Tests = _____% Quizzes = _____% Labs _____% and Homework / Classwork _____% of your quarter average. Extra credit will vary and can be used to make up points for missing Assignments. No more than 5 percentage points can be earned through extra credit per quarter. Students (and parents) are able to see their grades using Power Schools. Grades will be updated on Power Schools at least bi weekly.
X. Extra Help
Extra help is available most days from 7:40 – 8:14 in our classroom. Additional help is available at other times by appointment. (__________________ is the science No Extra Help Day)
In June, you will take the NYS Regents in Earth Science. You will be asked to purchase an inexpensive review book in order to prepare for this test. One portion of this test will consist of an in class lab proficiency assessment.
STUDENT RESPONSIBILITY It is your responsibility to get ALL missed work, to hand in
ALL assignments and PLAN AHEAD so you can succeed. Remember you are ultimately
responsible for your actions and inactions in the classroom-so make wise choices!!!!!!
I would like you to review this with your parents or guardians. I hope that it will help you better understand the requirements of this course and my expectations of you. I am looking forward to working with all of you and having a productive and enjoyable year ahead of us. If you have any questions or comments I can be reached though the school or by email. Thank you for your cooperation.
Sincerely,
Ms. Lee

RATE OF CHANGE
Directions: The questions are all based on "one year" for ease in learning to work with this
equation. Question
1- Mount Everest has risen 8.2 meters in the last 100 years. How many meters did Mount Everest uplift in one year?
2- A 1995 EPA study projects sea levels will rise about 30 centimeters (relative to the land) over the next century for the U.S. coast. Express this rise in sea level for a period of one year.
3- Scientists generally agree that erosion of the Grand Canyon started about 6 million years ago. The canyon, created by the Colorado River cutting a channel over millions of years, has attained a depth of about 1,600 m which is more than a mile. On the average, how many meters per year did the Colorado River downcut into the canyon?
4- Since the last period of glaciation, beaches on Kong Karls Land have risen 130 meters above sea level over the last 10,000 years. On average, how many meters have the beaches risen in one year?
