8th Grade Science 20132014
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.
3. BE SELFCONTROLLED!
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.
4. BE RESPECTFUL
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.
 Unsafe behavior and severe disruptions may result in immediate removal from the room and administrative referral.
Homework policy
Most homework will be short (515 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 http://www.hsd.k12.or.us.brown/homework.asp.
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 turnin trays, on the homework website, and on the Synergy website.
· Grades are based on 8^{th} 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 signup sheets in class. Students must sign up to retake tests (on the signup 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.

Nearly current grades will be available online in October, 2013 at http://synergy.hsd.k12.or.us. 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.
8^{th} grade Science Standards
Engineering Design
· MSETS11. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

Chemical Reactions
· MSPS12. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
· MSPS15. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
