SEMESTER FINAL

The Chemistry teachers would like to facilitate study groups for the Chemistry 1-2 final. This will be a student led study session.

WHO: Group leaders: Students currently with an A are encourage to sign up as group leaders with the incentive being volunteer hours and extra credit. More extra credit will be awarded to study groups held earlier in the week. To lead a group you must have solid knowledge and be willing to work with students assigned to your group. Study groups will be assigned by the teacher who is hosting the study session. Teachers will be responsible for assigning leaders.

Study groups: This is a great opportunity to complete reviews and get help in chemistry. If you are interested in participating in a study group, you must come to the study group with the appropriate materials. You will be assigned to a study group by the teacher hosting the sessions. You must actively participate in a quiet, respectful manner with the people you are assigned to work with.

Host: The host for this study session will be a teacher of the science department or a librarian. We reserve the right to ask you to leave if you are not actively participating (i.e. if you are too noisy, not following directions, or copying materials).

YOU MUST BRING STUDY MATERIALS

You must bring your binder and/or notebook with all semester assignments.

Any study guide materials that you have printed from the website or that you have been given by your teacher.

Study aids: Periodic table, calculator, polyatomic ion chart, conversion table, etc.

WHEN: 2:15 to 3:30 (You must arrive by 2:30); Tuesday, Wednesday, and Thursday

WHERE: Check with your teacher.
