Regents Chemistry Laboratory
Regents Chemistry Labs – These laboratory assignments are hands-on activities that students work in laboratory groups of 3 or more. Students will gather and manipulate (calculations) data together but will write their Lab conclusion independently (which compromises 20% of the lab grade). Please see how to write an appropriate conclusion.
The average of all Laboratory assignments per semester represents 30% of the quarter grade in PowerSchool. Lab grades in the Lab Section in PowerSchool are only reported as a means to evaluate whether students are satisfying the NYS lab requirement and thus only generates a pass/fail grade. Students who do not satisfy the NYS lab requirement will not be able to sit for the Regents Examination in June. This laboratory grade in the laboratory section of PowerSchool does not affect a students GPA but lab grades do impact the quarter grade.
Laboratory Requirements
Critical to understanding science concepts is the use of scientific inquiry to develop explanations of natural phenomena. Therefore, as a prerequisite for admission to the Physical Setting/Chemistry Regents Examination, students must have successfully completed 1200 minutes of laboratory experience with satisfactory reports on file. Because of the strong emphasis on student development of laboratory skills, a minimum of 280 minutes per week of class and laboratory time is recommended.

*Since this is such a lab based course, students who complete, turn in, and earn a satisfactory (75) on the first 15 lab assignments have met the NYS requirement. However, since each lab assignment counts toward your quarter grade (average of all labs has a 30% weight) it would be unwise to stop completing labs assignments for
2 reasons.
1: You will probably not pass each quarter. (Students would need to have a test average of 95 and at least a 80 average on your quiz grades to earn a 65 in a quarter that no labs are turned in.)*
2: Labs parallel what is taught in class as to increase student learning on concepts that are needed to succeed on each test (which has a large weight in quarter grades, 60%).
**Labs that are handed in late (after the due date are penalized 2o points.) There is no penalty if the student contacts me PRIOR to the due date and asks me for an extension I understand that students have many commitments and things honestly do come up. If I feel a student is abusing this privilege then they will be penalized accordingly. Students must learn to talk with their teachers, professors, and eventually their employers. The way to contact me is through email so that there is a record. My email is posted on the home page of this site. Email me Anytime!
Students who miss the due date by a week will have a permanent zero in PowerSchool. Zero’s are placed in PowerSchool whenever an assignment is not handed in on time and can change if handed in late or extensions are awarded through communication with me.
Good luck! Lets go!
