Update for 12-21-2018

Here is the update for the Christmas holiday:

Regent Chemistry 1:
• Unit 4 Exam:  Chemical Bonding has been completed today.  If you missed it, it's your responsibility to ask for make up when we come back from the break.
• Lab. Report #14 will be DUE 1st day after Christmast break.
• No new assignment for Christmas Break.

Earth Science 1:
• HW#19 Worksheet - Sedimentary Rocks Worksheet and Lab. Sheet #14 are both PAST DUE.
• If you missed Quiz#3 today, it's your responsibility to ask for make up when we come back from the break.
• In view of the fact that we come back to school on a Wednesday, the posting of Unit 4 Review will be delayed, and Unit 4 Exam likely will be on the Tuesday of 2nd week after we come back.  (Hence, no new assignment for Christmas Break...)


That's all folks, Enjoy a Happy & Safe Holiday, see you all next year!!
