Classroom Rules and Expectations


I think that I have very simple, straight-forward classroom rules and expectations. I will be discussing these in class, but here's a quick recap:

  • Please be on-task during classroom time (visit later)
  • No cell phones (as per school policy); if your parents really need to get in touch with you, they should call the office. Please don't bring cell phones to class, or if you do, please remember to turn them off!
  • Please don't listen to music on MP3 players or iPods during class time, UNLESS I have given you permission to do so.
  • Be polite. You should be listening during class lectures or when your classmates have questions to ask (you might have some of the same questions).
  • Be on time. If you are late, please enter the classroom quietly and apologize for being late. If the door is locked, I have started the lecture or there is a class presentation in progress; I will open the door and let you in as soon as possible.
  • Clean up after yourselves. Please don't leave garbage on the floor. I like my classroom fairly neat and tidy.
  • Don't bring junk food to class. Healthy snacks only. Or you could always wait until lunchtime.
  • You may chew gum in class on the following conditions: don't chew like a cow, I don't want to see the gum or hear you chewing it, that's just gross.
  • Late assignments: 10% is deducted for every day an assignment is late. If you have an excused absence, then there is some flexibility with this rule.
  • Please make sure that a parent or guardian calls the school to have absences excused. If you miss a test due to an unexcused absence you will be assigned a mark of "zero".
    I will be contacting parent/guardians if you have unexcused absences.
  • Please adhere to the school's academic honesty policy.
  • DO NOT go on holidays!


Here are some simple rules that I have established for using the blog, and some other informational items:

  • Please post on the blog anonymously.
  • If you feel the need to identify yourself, or clarify which grade you're in, please use your initials and your class and section (for example, K.G. in Social 10-2).
  • Some of you may have your own Blogger accounts. Please don't post on this blog using your Blogger ID, otherwise you may have people visiting your blog that you may not want to see what you're posting.
  • Please be courteous, polite and respectful when posting comments on the blog. Don't be rude to your classmates on the blog.
  • Please be patient with my response time.
  • Please post comments and questions on the blog prior to 10 p.m.
  • Between 6-8 p.m. I am usually not online.
  • Please do not post links to questionable materials.
  • Inappropriate comments will be deleted. Please don't do this, it's a waste of my time, I could be doing more productive things, like answering questions that you may have.

I will have drop-in hours next week (except on Monday, I'm supervising English 30-1) if you have questions. You could also send me an e-mail if you have a question or post a comment in the discussion thread above. I am also offering a Diploma Exam Review Session on Wednesday, June 23 from 10 a.m. to 12 p.m. This will be a structured review to help you with Part B of your Diploma Exam.


We played a review game of Jeopardy today. I have sent this PowerPoint game to you by e-mail. If you have any exam-related questions next week, please come see me in my classroom (except on Monday the 14th, I'm supervising English 30-1). You could also send questions by e-mail (to my CBE mail account) or post a comment in the discussion thread above.

June 9


You broke into small groups today to brainstorm arguments and evidence related to a text-based source (similar to what you would encounter on an essay). After we brainstormed and recorded the ideas, I split you into two large groups, one arguing in favour of the perspective in the source and the other against it. In these larger groups you thwn had to decide what arguments you would develop and what group members would responsible for their development. Both classes put together an essay outline, which I have sent to you by e-mail. Have a look at it tonight. You have Part A of your Final Exam tomorrow. Please go directly to the Blenheim Room tomorrow morning.


We finished off formulating arguments and evidence for yesterday's economics-themed essay, and today we looked at a source that a more political theme to it. I broke you into five groups and each group was responsible for developing its own essay outline. I collected the outlines at the end of class, I will scan them and send them to you tonight. I have sent the economics-themed essay outline to you, so please look for it. You have your Social 30-1 Comprehensive Final Exam tomorrow. Be prepared!

Tuesday, June 8, 2010

June 8


I split you into small groups to brainstorm arguments and examples for an economics-themed essay. Of course the text-based source will be different on your Diploma Exam, but I think it's useful to get into positional thinking and generating arguments and potential evidence so that if you were given an essay with a similar theme you might be able to write on the subject. We'll finish this essay outline tomorrow, and then we'll move on to a political-themed essay outline tomorrow. Please remember that your Chapter 13-14 Study Guide Questions are due tomorrow, and that your Comprehensive Final is on Thursday.


I gave you some time to work on the multiple choice questions from Chapters 15 and 16 today. Hopefully, this two day exercise gives you a sense of what questions from Unit 4 might look like. I also gave you the Social 20-1 Final Exam Study Guide today.

Monday, June 7, 2010

June 7


We looked at the Social 30-1 curriculum/program of studies today to see what concepts were emphasized in the document. As I went through the curriculum, I asked you to write down certain key ideas. Here's a link to the Social 30-1 Program of Studies and a link to the Social 30-2 Program of Studies. I have sent you the 10 page study guide that I made up for Social 30-1 and 30-2, so please check your e-mail accounts. I'm also including a link to the Student Guides to Writing the Diploma Exam page on the Alberta Education website. Print off a copy of this guide for yourself. Also, once again, have a look at the Student Writing Samples for 30-1 and for Social 30-2. It should give you a better insight into expectations for Part A of the Diploma Exam. Please remember that your Chapter 12 Key Terms and Questions are due tomorrow, and your Chapter 13-14 Study Guide Questions are due on Wednesday. Your Comprehensive Final Exam is on Thursday, STUDY!!


I gave you back your Unit 3 Essays today. I also gave you feedback with regard to your Unit 2 Collaborative Inquiry Projects. I gave you some time to work on Unit 4 multiple choice questions with a partner. We'll work on Chapter 15 and 16 Questions tomorrow. I will be doing a homework check on Chapter 14-15 and Chapter 16 Key Terms and Questions as well as the "Regional Disparity" PowerPoint presentation. This is the last homework check of the semester.

Pembangkit Listrik Tenaga Osmosis

Kebutuhan terhadap sumber energi, terutama energi listrik, mendorong munculnya banyak variasi sumber pembangkit. Terlebih adanya desakan untuk menciptakan sumber pembangkit ramah lingkungan, menjadi salah satu faktor pendorong untuk mencari sumber energi lain selain bahan bakar fosil. Salah satu yang saat ini sedang ramai adalah pembangkit dengan konsep renewable energy yang umumnya sudah banyak dikembangkan di negara – negara maju. Salah satu bagian dari renewable energy adalah pembangkit listrik menggunakan teknik energi osmosis yang akan dibahas pada artikel ini.

Pada prinsipnya, proses pembangkitan listrik melibatkan perubahan energi kinetik menjadi energi listrik (memutar rotor pada generator). Energi kinetik inilah yang umum menjadi permasalahan. Hal ini dikarenakan pada metode pembangkitan secara konvesional (seperti pembangkit berbahan bakar fosil) bahan bakar tersebut akan dibakar untuk memanaskan air, yang pada proses selanjutnya akan menghasilkan tekanan untuk memutar rotor. Hal inilah yang kemudian dilihat dan berusaha dimanfaatkan pada proses osmosis.

Berdasarkan pengertiannya, Osmosis merupakan salah satu sifat yang dimiliki dari benda cair (fluida) untuk berpindah melalui lapisan semiperrmiabel diantara 2 fluida yang memiliki kepekatan berbeda. Lapisan semipermiabel ini berfungsi untuk memisahkan 2 lapisan dan hanya mampu ditembus oleh air, sementara partikel yang lain tertahan. Sehingga arah pergerakan fluida berasal dari fluida dengan kepekatan rendah menuju fluida dengan kepekatan lebih tinggi hingga dicapai kepekatan yang sama.

Perpindahan fluida ini akan mengakibatkan adanya perubahan volume yang juga mengakibatkan tekanan pada sisi fluida yang lebih pekat. Tekanan ini kemudian akan menyebabkan pergerakan fluida dan tekanan yang dapat digunakan sebagai sumber energi kinetik. Konsep inilah yang kemudian digunakan pada pembangkit listrik dengan konsep teknik osmosis dengan memanfaatkan air laut. Dengan memanfaatkan kepekatan air laut dan juga air murni, pembangkit listrik dengan teknik osmosis dapat dikembangkan.

Untuk lebih memahami mengenai proses osmosis, dapat dilihat pada gambar di bawah ini.


Pada kondisi awal


Pada saat proses osmosis telah mencapai titik keseimbangan

Teknik osmosis yang digunakan pada pembangkit listrik memiliki 2 tipe yang berbeda, yaitu SHEOPP Converter dan Underground PLO Plant.

SHEOPP Converter

SHEOP Converter merupakan pembangkit listrik yang terpasang di dasar permukaan laut. Prinsip yang digunakan pada pembangkit ini adalah menggunakan air laut sebagai fluida pekat, dan memanfaatkan aliran air sungai atau dam yang berfungsi sebagai fluida yang kurang pekat. Dasar peletakan pembangkit ini didasar laut dikarenakan faktor beda ketinggian dan juga kadar kepekatan air laut itu sendiri. Faktor ini cukup mempengaruhi energi listrik yang nantinya dapat dibangkitkan.


SHEOPP Converter Plant


Underground PLO Plant

Pada prinsipnya, tipe pembangkit Undergorund PLO Plant memiliki prinsio kerja yang sama dengan SHEOPP Converter. Perbedaan terletak pada penempatan pembangkit. Jika pada SHEOPP Converter, pembangkit diletakkan pada bagian dasar laut untuk memastikan tekanan dan jumlah fluida yang tepat, maka pada pembangkit tipe Undergorund PLO plant pembangkit diletakkan di bawah tanah. Hal ini yang didasarkan untuk memunculkan perbedaan tekanan, dengan mengalirkan air dari sungai atau dam dan air laut menuju ke level tekanan yang lebih rendah. Untuk lebih jelasnya, dapat dilihat pada gambar di bawah ini :


Underground PLO Plant

Akan tetapi, seperti banyak pembangkit renewable energy lainnya, konsep pembangkit dengan teknik osmosis masih mendapat banyak tantangan. Hal ini terkait dengan faktor – faktor kualitas, kuantitas, dan ekonomis yang kurang baik. Permasalahan terutama terpaku pada kemampuan lapisan semipermiabel sebagai bagian penting teknik ini, dan juga faktor biaya yang dibutuhkan dalam menghasilkan energi listrik per Watt-nya.Oleh karena itu masih sedikit pembangkit listrik dengan teknik ini yang dikembangkan.

Perkembangan pembangkit dengan teknik ini sampai sekarang, hanya terdapat beberapa tempat , diantaranya adalah oleh perusahaan Starkraft di Tofte, Norwegia dan Eddy Potash Mine di New Mexico. Bahkan ketika pertama kali dibangun, pembangkit listrik yang berada di Norwegia hanya mampu menghasilkan beberapa kilo-Watt yang jika dikonversikan hanya dapat memanaskan air untuk 1-2 ketel.

Perhatian pada pembangkit ini pun akhirnya menarik beberapa pihak untuk meneliti dan menelaah lebih jauh. Salah satunya adalah perhatian untuk peningkatan kerja pada sisi lapisan semipermiabelnya. Namun, seiring waktu berjalan, bukanlah sesuatu yang tidak mungkin apabila di masa depan pembangkit dengan teknik ini dapat menjadi salah satu bagian dari sistem pembangkit listrik dengan dasar renewable energy.
