Today we looked at how we can use proportional shapes to represent the river data we will collect. You all drew some fantastic flow arrows and most of you complete the proportional squares for average particle size too.
When your data presentation section of your controlled assessment is completed, you will move onto interpretation. Your final interpretation will be done in high control conditions without help, so it is important we have plenty of practice writing.
The key concepts of your investigation will include (key words and processes that run throughout the investigation) velocity, attrition, vertical erosion, lateral erosion. You must ensure you refer to your key concepts when you interpret your data.
The stages of the interpretation should be as follows:
1. Describe the data. How has the data changed between the sites, has it increased or decreased? You must manipulate the data by saying how much it has gone up or down by as a % or a fraction.
2. Explain the data using the key concepts. For example if you are explaining why the velocity has increased you are automatically talking about a key concept of the project. You may be able to link to other key concepts once you have interpreted several aspects.
The Bradshaw Model is a theoretical model to tell us how a river should behave as it runs down the long profile from source to mouth.
Include reference to the Bradshaw model in your writing. Mention what the Bradshaw model suggests will happen to velocity, for example.
When we write our real interpretation you will need to refer to your hypothesis and aims of your investigation in order to write a conclusion. We will look at how to do this after the holidays.
For now, have a practice at describing your data on the flow arrows and proportional squares we drew with sample data in class. Remember to manipulate the data and explain the data.
Remember also you have your end of year geography exams w/b 23rd June. You will be examined on ALL the geography topics you have done so far. You will have 2 exam papers.
Have a good break.
