Revising for the field work exam – Paper 3

Jurassic_Coast_web

You need to know, understand and skilfully use these words to be able to do well in Paper 3 of your exam; the field work paper

Key Term Meaning
Primary data collection Information you have collected yourself
Secondary data collection Information someone else collected
Qualitative data Information that is NOT expressed as numbers or numerical data, eg as present or absent, feelings, or as colours.
Quantitative data Information that is expressed in numbers
Spatial sampling Either points along a line (linear of line sampling) or using a quadrat
Random Sampling Where every person or place has an equal chance of being measured. Decisions are made using random number tables
Stratified sampling Dividing sampling into groups, eg three sites from each section of coastline, or five people from each age range. It is possible to combine stratified sampling with random or systematic sampling
Systematic sampling Collecting data in an ordered or regular way, eg every 5 metres or every fifth person.
Opportunistic sampling Where you make decisions in the field or on the day based on the conditions you find there
Accuracy of data collection Ensuring all data is collected correctly
Reliability of data collection Ensuring all data is collected consistently

 

Revision tips:

1/ What are the differences between the last two key words?

2/ What are the advantages and disadvantages of each type of sampling technique? A recent 6 mark exam question was Evaluate the strengths and weaknesses of systematic sampling for collecting pedestrian flows.” So to help revise you could replace “systematic” with any of the other sampling strategies from the table and practice that as a 6 mark question.

Global Atmospheric Circulation

bbc atmosphere

This title makes this sound a difficult topic to revise, but it isn’t. firstly, global = over the whole world, then atmospheric = to do with the atmosphere and finally, circulation = moving around. In other words its how and why the atmosphere moves around the Earth. And once you know this you can then link it to the ecosystems topic, as global atmospheric circulation controls a lot of world climates which of course influence different BIOMES. (The two biomes we studied are: semi-arid and tropical rainforest.)

Firstly remember that

Rising air cools as it rises, so it cools, water vapour will cool, clouds will form and therefore three is a HIGHER CHANCE OF PRECIPITATION IN AREAS OF LOW PRESSURE (sometimes called depressions)

Descending air warms and therefore there is no condensation and LESS CHANCE OF PRECIPITATION IN HIGH PRESSURE AREAS (sometimes called anticyclones)

Since it is hotter at the equator, air rises here and creates area of low pressure. (So there is a lot of rainfall here. This is where you get tropical rainforests.) This risen air spreads out from the equator, cools and descends around 30 degrees north and south of the equator (area of less rainfall so deserts and semi-arid biomes here). This paragraph describes the movement of the Hadley cell which you can see in this diagram; it is labelled 1.

Additionally the rest of the global circulation is very well explained by this American teacher to his class. You need only watch up to 4:00 minutes.

Once you think you understand this global circulation, test yourself and use p. 75 from the revision guide to link global atmospheric circulation to biomes. If you need some more help with this you can read p. 210-11 in New Wider world.

Birds and Stakeholders and Coastal Management

birds net cliff norfolk

Simply read this BBC article from earlier in the months and as long as you understand how it shows how different people (called stakeholders) can have different opinions about the best way to manage coasts you will have learnt a very useful thing for your GCSE exam

  • What does the council want to achieve with the nets?
  • Why is the RSPB angry with the nets?
  • Who do you think is correct here?

Revising River processes and Landforms

IMG_8357

What you need to know:

  • Describe and explain 4 types of erosion – abrasion, hydraulic action, attrition and solution
  • Describe and explain 4 types of transportation- traction, saltation, suspension and solution
  • Describe and explain the formation of landforms in the upper and lower section of the river including floodplains, meanders, waterfalls, gorges, and V shaped valleys and ox-bow lakes

Below is a powerpoint designed to help you revise this part of the Rivers and River Management topic. It covers processes and landforms. Beware you have to do the work to revise. this is no quick fix.

Revising river processes and landforms

videos on Processes

  • If you follow this link you get to the time for geography video on river EROSION processes. Its excellent!
  • and this link will take you to the same site and their equally excellent video description of TRANSPORT processes

Videos on landforms

  • waterfalls and gorges (upper course feature) click here
  • floodplains and meanders click here

Also here is a Kahoot! quiz  (just the 10 questions)

Revising an HIC Global City – Sydney

 

sydney

Firstly Sydney comes in the global cities topic (along with mumbai -see this revision page) you can find the PLC and skeleton revision card for this topic on these two links global cities    global cities PLC

Here is a list of what you need to know (shortened from the PLC)

  1. Describe how migration and natural population growth have caused Sydney’s growth.
  2. Explain how the growth of Mumbai has affected the social and economic features of the city and how it has become harder to manage sustainably.
  3. Describe and evaluate the different ways that people have tried to manage these economic, social and environmental problems.

 

Mr Hunt has produced this excellent all in one basic revision resource that covers everything you need to know (but you will also need to evaluate the ways people have tried to manage Sydney’s problems). It is centred on the text book, but if you don’t have access to that you could still try to do this at home and check it when you get into a geography classroom. Link is here Sydney

This is the revision lesson presentation you will have or have already had. Following the instructions on this (you will need a copy of the text book) will help you get a complete grounding in all that you need to know. 2 Sydney revision 

This video is all about how Sydeny is trying to sustainably manage their parks and walk ways and public spaces. Watch this and write down all the sustainable benefits you can think of (people and environment remember) For top top work (grades 6-9) use this table to write your notes on sustainable management. It classifies them by the Egan wheel and would enable you to get the best marks if you could use it well in the exam. Egan and Sydney

Here is a old post with 2 videos on Sydney’s transport problems and how people have tried to manage the sustainably. There are questions I have written as well to help you notice the ‘useful stuff’.

Revising a LIC Global City – Mumbai

It is centred on the text book, but if you don’t have access to that you could still try to do this at home and check it when you get into a geography classroom. Mumbai Case study worksheet

This revision task goes further than the one above and is best if you are aiming for a grade 5 and above. It gives you some information that you can take notes on and then test yourself, but there are also some gaps so you have to research and find this information in your book or the text book. This (if you do test yourself on it) is a good resource to revise from. Mumbai revision notes

Here is video to show what Mumbai looks like frm the air

The first 1:53 of this is excellent on how Mumbai is a global city. The rest of it is excellent on some of the social, economic and environmental problem Mumbai faces

Finally, if you want to see the powerpoint of the lesson you were taught on this in year 10. so you could do some of the work from it (maybe slides 10-15) here it is. mumbai lessons complete 2018
