Here is the update for today:
Practical Chemistry:
• For the preliminary design proposal you submitted today, I will look it over and comment on it over the weekend (it'll be graded as homework). In the mean time, you should keep researching for further modification and start to gather all the supplies needed to construct your water purifier.
Regent Chemistry 1:
• (From yesterday's posting) HW #16 (Due Wednesday) - Complete Atomic Structure Worksheet (you should be able to complete the first side by now). The backside can be completed after the lesson on Monday.
• Reminder: Lab. Report #6 is due on Monday.
Have a good weekend.

Here is the update for today:
Practical Chemistry:
• Today we have distributed the guideline for the Homemade Water Purifier project. Many of you have failed to indicate whether you will be working in groups or by yourself. Be sure to submit your preference first thing tomorrow morning.
Regent Chemistry 1:
• Unit 2 Exam will be held tomorrow, be sure to bring a "real" calculator, references tables, and pen or pencil. The key to Unit 2 Review sheet can be downloaded here. Be sure to study the review sheet as well as your notebook.
• Reminder: Lab. #6 will begin tomorrow morning during P1 in Rm. 311.
To all classes: If you would like to check your updated marking period grade, log into the Snapgrades to find out...

Here is the update for today:
Practical Chemistry:
• REMINDER: If you don't hand in your homework, most likely this will lead to a failure for the course. As of end of today, I have not receive that many Classwork #1 assignments. Be sure to make up this assignment and submit it for Monday.
Regent Chemistry 1:
• Reminder: Lab. Report #5 due next Monday.
• There would be no HW this weekend. However, since Unit 2 Exam is going to be next Tuesday, you should start studying your notes and practicing Gas Law problems in the textbook.
Have a good weekend.

Update for 10-21-2010
Here is the update for today:
Practical Chemistry:
• Please answer the following questions for Classwork #1 and submit the work for tomorrow: (To be counted in HW category)
1. Consider oil-water separation, sand filtration, charcoal adsorption and filtration, and distillation. Which purification procedure would be least practical to purify a city’s water supply? Why?
2. You are marooned on a sandy island surrounded only by ocean water. A stagnant, murky pond contains the only available water on the island. In your survival kit, you have the following items:
• One nylon jacket • One plastic cup
• two plastic bags • One length of rubber tubing
• one knife • one 1-L bottle of liquid bleach
• one 5-L glass bottle • one bag of salted peanuts
Describes a plan to produce drinkable water, using only these items.
3. A group of friends is planning a four-day backpacking hike. Some members of the group favor carrying their own bottled water. Other members of the group wish to carry no water, instead, they will buy bottled water in towns along the trail; still others want to purchase and carry portable filters for use with stream water.
a) What are the advantages and disadvantages of each option?
b) What additional information would the group need before deciding on a group plan?
Regent Chemistry 1:
• If you have not finished HW #14, be sure to complete it and submit it for tomorrow. Otherwise, no new HW for today.
• Reminder: Lab. Report #5 due next Monday.
• Unit 2 Exam likely to be next Tuesday.
