Special things for those taking exams in 2012

Case studies:
1 Rising demand for water: UK textbook pages:18- 20
2. Large dam or reservoir: Three Gorges: Pages 25 & 26 and also http://ih-igcse-geography.wikispaces.com/1.8+Clean+Water and PP from lesson 6 below.
3. Case study of a flood defense scheme : Bangladesh P30-1 in textbook; also https://lindym.wordpress.com/2011/11/29/bangladesh-flood-management/ a new article added to the blog that gives you enough for 9 marks in a last question

These are the lessons used by the 2011 Exam cohort - you might find some PPs useful but not specifically.

There some good animations of processes there too

These 2 are the ones for homework but the the last one is the general one which will take you into more material in flash

PowerPoint for the lesson:
Classwork notes:
Homework: Each homework sheet may be a bit different as you are doing different things - please make sure you do the questionnaire, so I can ensure you have all you need
No notes on fieldwork – check again with the PP. Use the wiki http://ih-igcse-geography.wikispaces.com/1.10.+River+Coursework

Also http://www.georesources.co.uk/darentfte.htm is a help with describing the methods

Lesson 8

Objectives: to answer the following questions
  • How much can you remember?

  • What are all the words and meaning associated with the hydraulic cycle?

  • What are the features of a river basin?

  • What are the flows, stores, inputs and outputs of the river basin?

  • How does the shape of the hydrograph relate to the activity/structure of the river basin?

PowerPoint for the lesson: Please note this is also 3 weeks worth of PowerPoints - see comment below
Classwork notes:Please note that this set of notes is for 3 weeks, as I am not sure how fast we will be moving through them

Homework: But the homework is for this week only!!


In some I make a mistake in b(ii) - the correction should have said:
Before and after the Hoover Dam, the average is changed a little as it is slightly less erratic down stream from the dam. However the variation from maximum to minimum is very much reduced.
Before and after the Glen Canyon Dam, the variability of the average is reduced further and stays close to 1,000 cumecs.


I am updating the textbook wiki http://ih-igcse-geography.wikispaces.com/ with new stuff but with all those pages, how can you find where I have been?
On the left hand-side, there is a link called RECENT CHANGES. Click on that and you can see exactly which pages I have been fiddling with!

Lesson 9

As I mentioned before the PowerPoint and the class notes will run over 3 weeks.
As for the homework, no written work to give in this week, but you need to learn your KEYWORDS for this section - see the document below.

The emailed River chapter may be of use here?
One neat way, may, is to put them in a game. Here is one example:
Follow the instructions to add your questions.
Save (bottom right of the screen) and then copy the address from the address bar and email me with it - I will then post it in Top Homeworks so the others can share it.
BUT if you do not copy and save that quiz will disappear into the ether forever as there is no way to trace past quizzes without the link!

Lesson 10

Nathan's fantastic PP - do look at it for inspiration

For those of you who cannot remember about drip irrigation or Zai holes - here is another example of using water carefully to look at
