Chemistry & math tutorial are available in my classroom Fridays after school from 3-4:30. If minimum day on Friday, I will have tutorial immediately after school.    
  • Homework Assignments are expected to be completed even though they are not weighed in any grading category.  These homework assignments are assigned to support a student's learning of content learned in class.
  • Retakes for quizzes are available to all students.  To retake quizzes, students must complete assigned homework, and meet with the teacher to demonstrate comprehension.  Retakes are given at the discretion of the teacher (based on student comprehension).
  • Participation in Lab Investigation.  Occasionally, lab investigation opportunities are provided to students.  Students who participate in lab investigations automatically get partial lab credit.  Participation is defined by answering correctly a set of reflection questions presented towards the end of the lab investigation during the allotted class time. 
  • Missed lab investigation.  Students who miss lab investigation are given one week to complete lab during after school tutorial.  No credit after one week.
  • Late blog response. No credit given.  
  • Late completion of reading assignment. No credit given.
