Students, the following are websites that may offer you more assistance on some of the concepts we'll encounter in Unit 1.

http://www.aaastudy.com/mea212x2.htm
offers metric prefix information as does http://www.unc.edu/~rowlett/units/prefixes.html

Problems to work can be found at http://sciencespot.net/Media/metriccnvsn2.pdf and http://www.teach-nology.com/worksheets/math/measure/convert/1/
Problems on the test may be more sophisticated than these but the practice will help.

Significant figure rules are at http://dbhs.wvusd.k12.ca.us/webdocs/SigFigs/SigFigRules.html while practice can be found at http://chemistryandphysics.astate.edu/draganjac/Sigfig2.html

Scientific notation and calculator assistance are found at http://dbhs.wvusd.k12.ca.us/webdocs/SigFigs/SciNotMath-MultDiv.html and http://www.chem.tamu.edu/class/fyp/mathrev/mr-scnot.html

Chemical and physical properties are explored at http://www.teacherbridge.org/public/bhs/teachers/Dana/chemphys.html

A site with Celsius/Kelvin conversions is http://www.fordhamprep.org/gcurran/sho/sho/lessons/lesson29.htm

Homogeneous and heterogeneous mixtures are contrasted and compared at http://www.fordhamprep.org/gcurran/sho/sho/lessons/lesson14.htm

Additional safety guidelines can be found at http://library.thinkquest.org/2923/safe2.html

I hope these resources will be helpful to you : )

Enjoying those new books, students? Be sure that you take the time to look over the problems to ensure that you are proficient with the problems we've been working in class.

We will have a two day lab involving the conversion of copper. As you prepare for school, dress accordingly and wear closed-toe shoes. We'll start this lab on Tuesday, January 13. Have your lab notebooks ready with procedures already written. Reminder: page 1, title page, no number; pages 2 and 3 are table of contents with numbers; page 4 should be the first page of the copper lab. Only write on the fronts of the pages and number them all.

Plan for our first unit test to be on Tuesday, January 20, over chapters 1, 2, 3, and 25 in Lemay and Brown.

We agreed in class to have a couple of organic nomenclature/formula writing quizzes on January 14 and 16. You are responsible for alkanes, alkenes, alkynes, cyclic structures, and the functional groups we discussed in class.

Greetings honors students! Our first chemistry unit encompasses chapters 1, 2, and 5. Chapter 1 is an intro to chemistry. Chapters 2 and 5 are meatier chapters with terms and math concepts. The following is a list of SUGGESTED PROBLEMS for these chapters. As I explained in class, I will NOT be taking them up for homework. Instead, you need to work as few or as many as you need to succeed. Comprehension is key. There is a direct correlation between the working of problems and performing well in chemistry. I encourage you to work problems and answer questions until you are confident that you have mastered the information. The problems can be found by clicking the following link (continue reading Unit 1....) Happy reading and problem solving!

Essential Questions • How are instruments used to collect scientific data?
• What instruments are available, what are their limitations and how are these limitations modeled mathematically?
• What are the parameters by which matter can be classified?
• How do physical changes differ from chemical changes?

We will plan to test over this material on Friday, January 16.

Folks, consult http://www.ruf.rice.edu/~bioslabs/tools/notebook/notebook.html for more details on preparation of your lab notebook.

Another site to consider is http://www.dartmouth.edu/~chemlab/info/notebooks/how_to.html

This website may assist you with the layout of your lab notebooks http://home.clara.net/rod.beavon/lab_book.htm

Aim for having your abbreviated procedures for the copper lab in your lab notebooks by Tuesday, January 13.

Your first test will be on Friday, January 16, over chapters 1, 2, and 5. Stay on top of the problems so that you're not overwhelmed.

We will do several labs/activities in the next few days. Each will have an accompanying "report" to be submitted that will count as a daily grade. You will find that some lab write-ups require more effort than others. For the labs on Monday and Tuesday, 1/12 and 1/13, closed-toe shoes are not required.

While some of the quizzes on this website may be beyond you or possibly beneath you, this website does offer you the opportunity to try lots of different types of problems.

I encourage you to bookmark this site and use it for extra practice. Enjoy!

Please know that you are free to visit http://www.sciencejoywagon.com/chemzone/lessons/ at any time. Please bookmark this location. Honors students, this may be a good site for you to visit to expand your knowledge. AP students, this may give you needed reinforcement for ideas you're hazy on from first year chemistry. You will need a username and password that I am happy to provide to you. Stop by my desk and ask if you're interested : )

Greetings gang! We will be moving through the first three chapters of your Lemay and Brown Chemistry: The Central Science text rather rapidly. Come to class prepared to ask questions on any concepts that don't come back to you easily or that you weren't comfortable with the first go round.

Homework problems in this course are always suggested ones. I will not check your homework. There is a correlation between doing the homework problems and your performance on assessments. Incidentally, just because these are the problems that I suggest, you are by no means limited to doing only these. Knock yourself out and work as many or as few as you need to succeed.

Chapter 1: 15, 17, 27, 35, 39, 44, 58, 64
Chapter 2: 22, 23, 25, 27, 31, 49, 53, 55, 57, 59, 65, 57, 69, 71, 93
Chapter 3: 11, 13, 17, 19, 23, 33, 39, 43, 49, 51, 53, 57, 61, 73, 77, 89
Chapter 25: 6, 8, 13, 21, 39, 43

Answers to some questions are found in the back of your textbook. I have solutions manuals which have answers to other questions. The solutions manuals are on the bookcase in the front of my room and you can check them any morning before school as well as many other times.

Be sure you have a good scientific calculator. Happy problem solving! Do remember we are looking at testing on Tuesday, January 20, so be sure you're working problems.

I would like to offer some sites for help as I know there are some of you out there who would like to get a jump on the semester.

This teacher had all of his students make 4's and 5's on the exam . Amazing resource!

This site correlates to the Zumdahl book most recently used by Cobb County.

Greetings students and welcome to chemistry! This week, we will be learning a good deal about safety and starting our first unit on matter. On Monday, January 12, you will have a quiz over the safety guidelines you were given in class as well as the safety video we'll watch on Wednesday, January 7. You will have a quiz over the element names and symbols of the first twenty elements on the periodic table (hydrogen to calcium) PLUS iron, copper, zinc, bromine, iodine, silver, gold, nickel, lead, and tin on Tuesday, January 13. The best way to learn the element symbols and names is to make yourselves a set of flash cards and have someone in your family or a friend flash them for you. Be sure that you come to class prepared and ready to learn lots of chemistry : )
