Advanced Chemistry
2011-2012
Mr. Wood
Schedule- Class meets every day, with a double block once per cycle.
Text- Glencoe Chemistry: Matter and Change, Buthelezi, Dingrado, Hainen, Wistrom and Zike, 2008. We will use the text for reading and practice problems. You should bring your book to class every day.
Website- Many of the resources for this class will be found on my website www.mrwoodchem.com. This website is currently under construction and should be available sometime this summer. In the mean time former BHS chemistry teacher Mr. White is kind enough to allow us to use his website www.chemwhite.net for all your advanced honors chemistry needs.
Homework Policy- You are expected to read each chapter in the text prior to the related lecture. Problems will be assigned from each chapter of the text. We will go over these in class prior to tests and quizzes; homework will be graded for completion. From time to time you will also be given short writing assignments. These will be graded on an A-F scale with an emphasis on content, but also for clarity. Writing assignments will generally count as quiz grades.
Labs- Labs will be integrated into appropriate places in the curriculum. A comprehensive lab notebook will be maintained through each term and graded for quality and completeness. Writing a formal lab report is a fundamental part of this course, with two to three due per term. You will receive a format guideline sheet prior to the first formal lab.
Tests and Quizzes- Quizzes, worth 100 pts, will be given once or twice per unit of the text covered. Tests, worth 200 points, will be given at the conclusion of each unit. Emphasis for both is on problem solving.
Science Fair/Research- All students are required to do a science fair project as part of the honors curriculum. It will consist of the following: a general topic research paper term 1; and an experimental-based science fair project term 2, based on the research from term 1. There will be some class time allotted to support these projects, but much of this work will be done independently.
Grades- Term grades will be weighted as follows: Semester One- 10 % science fair/research, 5% homework, 25% lab work and 60% tests and quizzes; Semester Two- 10% homework, 30% lab work and 60% tests and quizzes.
Extra Help- I will generally be available for extra help, and to make-up missed work, after school Monday through Thursday. I expect anyone coming for extra help to have made an honest effort with the practice problems in the current chapter. Please try to notify me ahead of time if you will be staying.
Class Preparedness- Each day you should arrive on time with a notebook, your text book, something to write with, and any assignments which may be due.
Advanced Honors Chemistry is a challenging course, requiring a sustained and focused effort. Tips for success in this class- Do the reading assignments. Do your homework regularly; regular homework habits are the best preparation for tests and quizzes. Get organized! Good, neat notes are priceless when it comes time to review topics. And if you start to get lost, ask for help sooner rather than later. Also, we expect every person in the class to respect each other and themselves and to act in a responsible and adult manner.
Advanced Honors Chemistry Summer Assignment
Since chemistry is a complex discipline involving the simultaneous use of your big-picture, “word/idea” brain (right brain) and your linear-sequential, logical, “math” brain (left brain), it is imperative that you be both literate and numerate to succeed in the advanced honors chemistry course at Braintree High School. The summer work assignment for the course is designed to not only stimulate both of these faculties, but also help you make essential connections between them. Please have the work completed to turn in on the first day of class. There will be a quiz on this material on the second day of class.
Assignment:
Go to Mr. White’s website www.chemwhite.net and download and watch the first three podcasts:
a. Course Introduction Podcast
b. Metric System Podcast
c. Formula Problems Podcast
Have a calculator and a notebook and be prepared to actively watch, take notes and do practice problems.
Complete the attached practice problem sets, using the methods described in the podcasts. Make sure you have a complete solution for each problem, including all proper units.
Perform the following conversions as indicated. You may work on this sheet.Show complete solutions and all units.
Single Step
1. ___ m = 23 cm x ______mcm / 2. ___ mm = 1.6 m x ______mm
m
3. ___ m = .4 km x ______m
km / 4. ___ cm = 3.2 m x ______cm
m
5. ___ m = 2.7 mm / 6. ___ mm = 1.3 m
7. ___ m =12km / 8. ___ mm = .96 m
9. ___ ml = 6.2 l / 10. ___ g = 12.3 mg
11. ___ mg = 23.1 g / 12. Convert 4.31 kg to g
13. ___ km = 342 m / 14. Convert .067 g to mg
Multiple Step
15. ___ km = 785.6 cm x ______m x ______kmcm m
16. ___ mg = .27 kg x ______g x ______mg
kg g
17. ___ mm = .84 km
18. ___ ml = 12.6 l
19. ___ mm = 7.22 cm
20. Convert 834.0 cg to kg
21. Convert 729.9 ml to dl
22. Convert = 47.2 mm to km
23. Convert 0.33 dl to cm3
24. Convert 1. 92 kg to mg
Please solve the following problems on separate sheets of paper. Show complete solutions and all units.
1. A gold-colored ring has a mass of 18.9 grams and a volume of 1.12 mL. Is the ring pure gold? (The density of gold is 19.3 g/mL.)
2. Pumice is volcanic rock that contains many trapped air bubbles. A 225 gram sample occupied 236.6 mL. What is the density of pumice? Will pumice float on water? (The density of water is 1.0 g/mL.)
3. What volume would a 0.871 gram sample of air occupy if the density of air is 1.29 g/L?
4. A cup of sugar has a volume of 237 mL. What is the mass of the cup of sugar if the density is 1.59 g/mL?
