8th Grade Science 2013-2014            

Mr. Arrowsmith’s Class

Classroom Expectations

1.      BE RESPONSIBLE!  Purchase a 100 page (8 ˝ X 11”) composition notebook for use in science class only.  Students must have these by Monday, September 7.

Be in your seat, ready to learn, before the bell rings.

Come to class with your binder (including  your planner, pencils, eraser, paper, highlighters, scissors, glue or paste, colored pencils  and any homework you need to turn in) and your interactive science notebook (composition book).

2.   BE SAFE!!! IN SCIENCE LAB THAT MEANS: Follow the Laboratory Safety Rules.  These rules are posted in the classroom and a copy will be provided for your lab notebook. Students and parents will receive a copy of these rules during the first week of school. Unsafe behavior will not be tolerated in the science classroom.


Keep your hands and feet to yourself.  Don’t fool around. N0 HORSEPLAY! is the # 1 rule in my classroom. Pay attention to directions. Keep all 4 chair legs on the ground.


Respect yourself. Respect other students. Respect your instructors. Respect the community that provides you with this opportunity to learn, and take care of the school property you use in class.

5.     BE KIND! Jţ

What happens if a student behaves according to these expectations?

Students’ positive influence at Brown MS and in the classroom will be acknowledged with a “Great Panther” ticket, and praise! The tickets pay dividends!  Prizes and opportunities go to students who earn them.

What happens if a student misbehaves? 

1.      Warning – This is a reminder to the student: please  behave correctly.

2.     Warning with time out in the hall - Student will fill out a “REFLECTION SHEET” and may return when it is completed appropriately. 

3.     Tracker – Parents and administrators are notified. 

4.   Administrative referral - Each referral requires a meeting with an administrator concerning the misbehavior.

  1. Unsafe behavior and severe disruptions may result in immediate removal from the room and administrative referral.

Homework policy

Most homework will be short (5-15 minute) study questions designed to assure that students are reviewing their notes in their interactive science notebooks. Sometimes there will be a place for parents or guardians to sign showing that they have reviewed their student’s work. Descriptions of classwork and homework are available online at  

Grading Practices:

·         Students should make, keep, and use an assignment sheet that lists all assignments.  Each week’s assignments are posted by the assignment/homework turn-in trays, on the homework website, and on the Synergy website.

·         Grades are based on 8th grade state standards in science.  Grades are based on students’ performance on homework, tests, quizzes, CIM tasks, lab reports, and presentations.  Summative assessments will account for 55% of the student’s grade.  If a student has not successfully completed enough work to show that he or she earned a C, nearly meeting most of the standards taught in a grading period, a grade of I for incomplete may be given.  The student can improve this grade to a letter grade of C or above by successfully completing the missing work and/or work which did not meet the standard within 3 weeks of the end of the grading period.

·         Students may retake quizzes and tests to improve their grade.   Students must complete retakes before school, after school, or at lunch on days when Mr. Arrowsmith is available.  These days will be posted on retake sign-up sheets in class.  Students must sign up to retake tests (on the sign-up sheets posted in class) at least one day in advance.  Retakes may take a different form than the original test.

·         Written assignments may be redone or improved and resubmitted for an improved score.

·         Interactive science notebooks will be graded twice a quarter.


Balanced Grading Scale




What it means:

No Evidence

Nearly current grades will be available online in October, 2013 at  If you don’t have online access, Mr. Arrowsmith can provide nearly current printed information if you contact him by phone or send a note.  Check in at the main office for information on community online access.   Quarterly grade reports will be mailed home.                                                                                                    


8th grade Science Standards
