Update for 2-23-2010

Here is the update for today:

Regent Chemistry 2:
• I understand that many of you had not been able to finish the test given the shorter class period. Don't worry, the exam will be graded based on a curve, so the effect of insufficient time would be compensated.

SmartScience Online Lab Instructions (Chem 2 and Liv. Env. 2)

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.

• The student must complete the whole lab (Pre-lab Quiz, Post-lab Quiz, and Final Lab Report) in order for that specific lab. to be counted as "satisfactory". Since your interim progress report indicated the number of labs that you missed up to that point, you are responsible for making up those numbers of labs in a timely manner (preferably right after your missing lab. sessions).

• You can access the SmartScience online labs. in the following manner:
a) Go to SmartScience Lab's URL address directly; it is also accessible from our school's website: Go To Student => Labs
b) Select your class (look for Subject-Period with ending in Spring 2010), and then select 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 need to make up two Chem 1 labs, go to Chem 1 Lab List and select two lowest number labs (e.g. 1 & 2) to make them up. For make-up labs, work on the labs that are not assigned in class.
