Here is the update for today:
Chemistry 1 (SCS21):
• Since a lot of you from P5 were absent today, I am providing a downloadable PDF version of the lesson so you would know what was covered in class today.
• Quiz Tomorrow - Lewis e- dot diagram of atom, ions, and covalent compound.
Earth Science 1 (for both SES41 and SES21):
• Reminder: Mineral Application Research Project is officially PAST DUE as of TODAY
(both electronic version and hardcopy)! 20 pts. automatic late submission deduction become effective immediately.
• Your Lab. sheet #12 (including all questions on the back) is PAST DUE - submit it no later than tomorrow.
