Quarter Credit: For this quarter, course work will consist of: 2 projects 10 pts each 2 test 10 pts each Daily 3 questions 40 pts total (1 pt per day) Participation 20 pts total · In class (approximately on time, still in room when bell rings, only reasonable amounts of time out of the room) · On task (head up, working / participating, not distracting or disrupting others) Other than tests and possibly projects, students //must be present// to earn credit. (Make-up work for //excused// absences will be available on the class website and are to be handed in within a week of returning to class.)

<span style="font-family: Arial,sans-serif; font-size: 14pt;">Perfect Attendance Bonus: <span style="font-family: 'Times New Roman',serif;">Any 13 consecutive school days of attendance is eligible for a 5 point extra credit bonus, up to 3 bonuses per quarter. For multiple bonuses, the 13-day periods cannot overlap.

<span style="font-family: Arial,sans-serif; font-size: 14pt;">Expectations: <span style="font-family: 'Times New Roman',serif;">It is expected that anyone choosing to be in class is working toward our goal of learning enough physics to get credits. Respect is fundamental to helping everyone achieve that goal.
