SmartScience Online Lab Instruction/assignment

To My Regent Chemistry 1 Classes:

****************
For Tuesday 11/2/2010 Period 1 (and Period 9) Sessions: You are to complete SmartScience Online Lab. Titled: "Chemical Change" completely before your regular lab. report deadline (next Monday). This will be graded as a regular lab. and entered on your grade report.
****************

• 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.
b) Select your class (look for Dr.Liu-Period # RegentChem1), 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 term. 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 to make up the lab is to 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.

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. Hydrate Analysis Procedure
13. Analysis of Hydrates


• Write me an e-mail if you have any question (but read the whole instruction first).

Have a Good Summer Vacation!

To all my students,

Finally, the end of school year is here!!!

Sorry couldn't be with you guys on the last day - I'm having a little physical problem with my foot - hence the absence on the last day.

We have come quite far this year: To some of you, the successful completion of the course and the passing of the Chemistry/Living Environment Regent exam put the perfect ending to this whole year of hard work. To others, the best way to move forward onto next year of the new curriculum may be to find someway to finish the unfinished business during the summer (taking Aug. Regent Exam, or Summer School to get the needed labs and then the Regent Exam). The Regent Exam for Living Environment and Chemistry is going to be on August 18, 2010 (Wednesday) during the afternoon session. Please check with the main office or your guidance counselor about registering you for the Summer school/August Regent Exam.

Other than that, that would be all for now... Folks, Have a safe and happy summer vacation!!

Signing off,

Dr. Liu

Lab. #27 Part II Data

To Chemistry 2 Lab Students:

Some of you weren't able to finish the Part II of the experiment investigating the effect of surface area; I have modified the procedure a little bit and list the observations below:

• Modification: Use 40mL 2.0M HCl + 20 mL tap water for the acidic solution (instead of 10 mL 2.0M HCl + 50 mL water).

• Results: (You will calculate the reaction rate using the same formula on the lab sheet)

Test Tube 1 (Rolled): Reaction time is 102 sec; Observation: Was able to use the dropper to hold the rolled piece fully submerged within the solution.

Test Tube 2 (Flat): Reaction time is 50 sec; Observation: Was able to use the dropper to hold the flat piece fully submerged within the solution.

Test Tube 3 (7 pieces): Reaction time is 140 sec; Observation: Was not able to use the dropper to hold all little piece submerged, hence all the pieces stay on/near the surface with one side exposed to the air.

• Since the conditions of Test Tube 1 and 2 are similar, the effect of increased surface area should be made based on 1 and 2. Why do you think test tube 3 takes much longer time for Mg to completely react?
