Welcome to chemistry. Please use this site to communicate with your instructor and other students concerning your wet labs.

Bio Chem Wet Labs

2009-05-17T18:09:00.000-07:00

Hi all,

Please remember, all Lab Reports are due on May 22nd. I will be at Parkview from 3pm - 4pm to collect reports and answer any final questions. No lab reports will be accepted after this date, and any missing lab will go in as a "0".

If the time and date are inconvenient for you, please email me with a time and date that you will be passing in your work PRIOR to May 22nd. You may also leave your report with your regular teacher. If you choose that option, you will need to email me that you have done so, so that I know to pick it up on May 22nd. You may email any questions you have to my regular email address: rrubinstein@pylusd.org with any questions.

Also, anyone who did not complete the lab notebook, will need to have it checked. Do not forget to bring it in, if you have not already had it graded.

Please note: May 22nd is not a work session, you will need to have completed lab reports that follow the required format. Your lab notebooks have the format.

See you on May 22nd.

Mrs. Rubinstein

Final Wet Labs

2009-05-07T07:20:00.001-07:00

Reminder to all students:

Completed notebooks will be checked and graded on Friday, May 8th (our final session)

All previous lab reports are due on Friday, May 8th (NOTE: Make-up labs are not available, you are entitled to miss one lab class)

Reports for the lab on May 8th are due and will be picked up on May 22. Reports will not be accepted after that time.

Bio students: REMEMBER YOUR BONES!!!!!! This week's lab requires YOU to bring in dried bones. Come prepared.

Chem students: Make sure you read and understand this week's lab - you chose it!

Any questions? Email me.

Mrs. Rubinstein
