ENVIRONMENTAL CHEMISTRY UNIT IS ALMOST DONE!

THIS WEEK:

* Remember our fieldtrips start next week: 9H - May 20, 9E May 21, and 9B May 27

• Handed in our field trip forms and money; deadline is technically past
• We had our first LA PAT exam on Wednesday
• Created a 50 year plan for Alberta's electricity generation
• Finished up the Environmental Chemistry unit
• Began a work book that reviews the unit

YOUR UNIT TESTS WILL BE: May 21 for 9B, May 22 for 9H and May 25 for 9E

Study tips:

• Complete the review booklet using your textbook for help and the edquest notes
• Review the textbook; re-read any sections you do not understand
• Review notes for each section of the unit on www.edquest.ca
• Visit www.edquest.ca and practice quizzes/tests for the unit
• Practice calculating parts per million; practice with a friend!
• Need a video to remind you of a concept? Look up the topic on www.howstuffworks.com

WHAT WE DID LAST WEEK:

• Finished reading section 3.0 of the enviro chem unit
• Created 1 part per million using food colouring and practiced caluclating parts per million
• Graphed CO2 emissions per year and also per month and answered questions relating to the data

THIS WEEK IN GRADE 9 SCIENCE

LAST WEEK:

• We completed our electrical principals and technologies crate - great work!
• Continued reading about Environmental Chemistry
• This week we will evaluate your work done on the electricity crate and we will continue with Environmental chemistry

ASSIGNED WORK THIS WEEK:

1. Read section 2.0 (212-234)
2. Define the following terms: ozone layer, monitoring, biological indicator, invertebrates, parts per million, spring acid shock, pesticides, toxins, LD50, heavy metals, sulfur dioxide, nitrogen oxides, carbon monoxide, ozone, the ozone layer, greenhouse gases, enhanced greenhouse effect, global warming
3. Complete the check and reflect page 233 (#1-8) and the section review pg 235 (#1-11) but don't do #9 because you did a similar question on the check and reflect

THIS ASSIGNED WORK IS DUE WEDSNEDAY FOR 9E and 9B and Thursday for 9H

PLEASE PREPARE FOR NEXT WEEKS EVALUATION

Please prepare for next weeks evaluation by:

1. Reading the textbook. You should have read the entire unit by now including section 4 which was assigned for homework earlier this week
2. Complete all practice material: Ionic and Molecular naming/formula practice booklet, periodic table practice, and the previously completed ionic/molecular practice assignment
3. Re-read your section 2 quiz and practice with a friend (the tricky fill in the blank quiz)
4. Ensure you have practiced the questions assigned on page 149, 153 and 154 (specific questions to practice are listed on your naming cheat sheet)
5. Complete questions 1-26 on page 176-177
6. Visit: www.edquest.ca and practice the quizzes/tests for matter and chemical change

GET READY FOR ANOTHER BLIZZARD!

IMPORTANT ANNOUNCMENTS:

• MATTER AND CHEMICAL CHANGE UNIT TEST: Monday, March 2nd for 9H and Tuesday March 3rd for 9E and 9B

This week in Science:

• Continuing to learn about ionic and molecular compounds


• Learn more about chemical reactions by learning specifically about how sodium and chlorine form sodium chloride


• Learn strategies for writing formulas for ionic compounds


• Develop skills necessary to write the chemical names of ionic and molecular compounds using the formula


• Finish reading our Unit - if not done in class this week, please read section 4 of your Unit; this is assigned for home reading


• Begin preparation for your Unit evaluation (unit test) next week

FEBRUARY 2009

Hello grade nines! I hope you are all recharged after your time off. We are rapidly progressing through our unit, "Matter and Chemical Change"; be prepared to work hard in the next month (and for the rest of the year for that matter)!

Where are we in the textbook?

• You should have read all of section 1 and 2 and up to page 149 in section 3

What work should I have done?

• Finished check and reflect questions (1-4) on page 143 and page 149 (1-8)

I look forward to learning more about chemistry after the short break!

-Mr. Mang

This week in Science...

* We have now read to the end of section 2 of the unit Matter and Chemical Change; that means you should have read right up to page 134 in your textbook! You also have some homework due for next class!

• All matter in the universe is either a pure substance or a mixture (see picture)

HOMEWORK DUE: Complete the check and reflect questions (1-8 only) on page 134

Due: Wednesday for 9E and 9B and next Tuesday, Feb 3 for 9H

Remember: James Fowler tour is Thursday, January 29 and Friday you are off because teachers have a professional development day

WELCOME BACK!

I hope that everyone had a replenishing holiday! I am excited to teach you in the new year. Please tell me about your holiday some time, I would love to hear about it! We are of course studying "Matter and Chemical Change" at the moment and we will be studying this right into February. Be sure to keep up with the work, as this unit will challenge you! We will begin our studies after the break by examining how avalanches are caused by the unique, and diverse physical properties of water (frozen water); If you would like to learn more about avalanches, please visit: http://www.avalanche.ca/ for online courses, bulletins and more!

• You should have read the first section of the Unit (page 90-109)
• Completed check and reflect on page 96
• Define the key terms and complete check and reflects on page 104 and 109 - see key terms below

HOMEWORK FOR MONDAY (9e/9b) AND TUESDAY (9h)

• Define the key terms: matter, states of matter, melting, freezing, evaporation, condensation, sublimation, deposition, physical poperties of matter, melting point, boiling point, hardness, mallebility, ductility, crystal shape, solubility, density, conductivity
• Complete all check and reflect questions for the section (pg. 96, 104, and 109)

* This work will be due for a homework check next week

* You will have a quiz on the definitions next week...study them!
