Christmas Take-Home Exam Generated and Posted.

To my students:

Sorry about the delay, but now Christmas Take-Home Exam has been generated and posted for both Chemistry 1 and Earth Science 1 Classes. You should log into CastleLearning website to complete the exam. Be sure to do a good job on this one (as it has the potential to bring up your grade significantly). DUE DATE: Jan. 3, 2012.

If you have trouble accessing the website, you can also e-mail me so that I can send you the PDF version of the exam then you can print it out and work on it. However, if you do the print-out version, be sure NOT TO access the online version or your exam will not be graded.

Enjoy your holiday!

SmartScience Online Lab Instruction

To My Regent Chemistry 1 and Earth Science 1 Classes:

• The main purpose of SmartScience Online Labs is to provide you an opportunity to satisfy the NYS mandatory Regent Lab Requirement if you had missed regular in-class hands-on lab sessions. It is meant to be a supplement, not a replacement, of the regular labs. Hence, your performance on the online labs will not affect your regular course grade (unlike the regular labs which account for 20% of your course grade) - unless it's a lab specifically assigned by your teacher.

• Remember: If you fail the labs., you automatically fail the course - end of discussion. Hence, it's very important that you make up any missing lab online immediately (right after the week you missed your assigned lab session).

• The student must complete the whole lab (Pre-lab Quiz, Post-lab Quiz, Data Collection, and Final Lab Report) in order for that specific lab. to be counted as "satisfactory". F.Y,I, I do check your lab report, so if you do a sloppy job, you get no grade - "unsatisfactory"!

• You can access the SmartScience online labs. in the following manner:
a) Go to SmartScience Lab's URL address directly.
Make sure you select "NYC Public School" and then "Information Technology High School".
b) Select your class (look for LIU - Period # - Course Name - Semester Year); then use drop down menu to choose your name.
c) Type in your 9-digit StudentID (OSIS) number and select "Login".
d) Open the Window for the lab. session, this should start your JAVA running and get the session started. You will then be able to select the lab. activity. Be sure to click submit after you finish the entire lab (up to and include the conclusion of lab report).
* If you have trouble, make sure you use a different browser and make sure JAVA is installed on your computer (Preferred browser - Firefox).

• Listed below is a list of SmartScience online lab. activities that are assigned for Chemistry 1 and Earth Science 1 terms. I tried to arrange the order of the labs roughly according to the pace of our curriculum with increasing difficulty level, so the best approach for you is to find the labs for your to start with lower number labs first before proceeding to the higher number labs. For example, if you missed two chem 1 labs and need to make them up, go to Chem 1 Lab List and select two lowest number labs (e.g. 1 & 2) to make up those labs. In choosing the make-up labs, be sure to work on the labs that are not assigned in class. Send me an e-mail to notify me after you have completed the make-up labs (since I do not normally check the online labs unless I assign them specifically).

Regent Chem. 1 Lab List:
1. Lab Glassware Exercise
2. Measurement
3. Volume Graph
4. Chemical Change
5. Brownian Motion
6. Gas Volume-Temperature
7. Gas Pressure-Temperature
8. Liquid Volume-Temperature
9. Periodic Table Activity
10. Chemical Periodicity
11. Molar Volume
12. Absolute Zero

SmartScience Online Lab Instructions - 2011

To My Regent Chemistry 2 and Living Environment 2 Classes:

• The main purpose of SmartScience Online Labs is to provide you an opportunity to satisfy the NYS mandatory Regent Lab Requirement if you had missed regular in-class hands-on lab sessions. It is meant to be a supplement, not a replacement, of the regular labs. Hence, your performance on the online labs will not affect your regular course grade (unlike the regular labs which account for 20% of your course grade) - unless it's a lab specifically assigned by your teacher.

• Remember, starting from this second marking period, if you fail the labs., you fail the course - end of discussion. For 2nd marking period, you need to have a total of 21 labs or greater for the whole year, and for 3rd marking period, you need to accumulate 27 labs or greater for the whole year.

• The student must complete the whole lab (Pre-lab Quiz, Post-lab Quiz, Data Collection, and Final Lab Report) in order for that specific lab. to be counted as "satisfactory". F.Y,I, I do check your lab report, so if you do a sloppy job, you get no grade - "unsatisfactory"!

• You can access the SmartScience online labs. in the following manner:
a) Go to SmartScience Lab's URL address directly. (3/26/11: Link fixed.)
Make sure you select "NYC Public School" and then "Information Technology High School".
b) Select your class (look for Dr. Liu - Period - Course Name), and then choose your name.
c) Type in your 9-digit StudentID (OSIS) number and select "Login".
d) Open the Window for the lab. session, this should start your JAVA running and get the session started. You will then be able to select the lab. activity. Be sure to click submit after you finish the entire lab.
* If you have trouble, make sure you use a different browser and make sure JAVA is installed on your computer (Preferred browser - Firefox).

• Listed below is a list of SmartScience online lab. activities that are assigned for Chemistry 1 & 2 terms and Living Environment 1 & 2 terms. I tried to arrange the order of the labs roughly according to the pace of our curriculum with increasing difficulty level, so the best approach for you is to find the labs for your term (Chem 1 or 2, or LE 1 or 2), and then start with lower number labs first before proceeding to the higher number labs. For example, if you missed two chem 1 labs and need to make them up, go to Chem 1 Lab List and select two lowest number labs (e.g. 1 & 2) to make up those labs. In choosing the make-up labs, be sure to work on the labs that are not assigned in class. Send me an e-mail to notify me after you have completed the make-up labs (since I do not normally check the online labs unless I assign them specifically).
