Once we had looked at the structure of the course, and what you need to be doing in terms of reading, notes, organisation, etc., on Wednesday, we had a look at some key hydrological cycle terms.
Thursday's lesson was then spent looking at the systems approach, the idea of open (eg the drainage basin hydrological cycle) and closed systems (eg the global hydrological cycle), a recap of the features of a drainage basin. We then had a more detailed look at the drainage basin hydrological cycle, and you began putting together your hydrological cycle flow charts.
I've spent some time this afternoon marking these, and the exam question you did, and I am pretty impressed on the whole (not least with the fact that all of them were handed in on time!). We will start tomorrow's lesson with a quick look at those.

Year 12
On Monday, we started by looking at the systems approach - we talked about the global hydrological system as a closed system, and the drainage basin hydrological cycle as an open system.
We converted the drainage basin hydrological cycle diagrams you'd done for homework into flow diagrams, and had a look at a couple of exam questions.
We went on to look at the water balance and soil moisture budgets, and then river regimes.
Almost all of you managed yesterday to hand in your river regimes work via the new system - unfortunately two people have their first homework warning already!
On Thursday morning, we were out and about measuring infiltration rates around the school grounds. Remember that when you are writing up the investigation, you will need to include:
Aim
Hypothesis
Method
Results
Analysis/Discussion
Conclusion
Evaluation
Your graphs should be line graphs showing how the water level dropped over time.
As you know, I am not in school on Monday as it is Year 11's Burbage visit. In my absence, I would like you to look back at your flow diagram from Monday's lesson. For each component, I would like you to write a sentence or two to explain what that component is, and then to consider the factors that affect each component - eg when we talked about infiltration rates, we said that the permeability of the surface, soil compaction, antecedent moisture, etc. would all cause variations in the rates of infiltration.
Both your investigation write-up and the work I'd like you to do on Monday need to be ready for Thursday's lesson to hand in to me.
Don't forget, if you have any problems with it, email me or come and find me on Tuesday or Wednesday - don't just turn up on Thursday without having done the work!

Today's lessons...
AS
After introducing the course, outlining expectations and completing our profiles, we went on to look at the hydrological cycle. We talked about the systems approach and will look in more detail on Monday at the idea of open and closed systems. For Monday's lesson, you're putting all the key terms we talked about into a diagram... You might find the S-Cool website helpful if you are struggling.
Although you have the bits of the specification that you need, if you want to look at the whole thing, you will be able to find it on the AQA website
A2
After long discussions about Wales and AS results, we reminded ourselves about some of the key words and ideas that we need to consider relating to Recreation and Tourism. Again, some useful reminders on the S-Cool website.
There will be more information about Wales on Tuesday, but if you are planning a shopping trip this weekend, the OS map you need is OL17 - the Explorer (orange) map for Snowdon and Conwy Valley.

Test...
Because I am feeling kind and generous, and because we will probably need the whole lesson to do our infiltration investigation, we are not going to have the test tomorrow... But you can expect it at some point in the next few lessons!
You will need to know:
- key hydrological cycle terms (precipitation, evapotranspiration, surface run-off/overland flow, throughflow, groundwater flow, water table, baseflow, interception, stemflow, river discharge)
- concept of a system (closed and open... inputs, outputs, stores and flows)
- factors affecting the key processes we've talked about (eg infiltration rates varying according to amount of vegetation, etc.)
- water balance equation
- actual and potential evapotranspiration - differences between them and factors that affect them
- soil moisture budgets
Remember to keep your glossary of key words going as we go along... And don't forget the ideas for learning key words and ideas that we talked about on Tuesday - mind maps, post-its, etc.

Lesson 1
So, a good first lesson!
We looked at the concept of a system - you need to know the difference between a closed system and an open system. (The global hydrological cycle is a closed system, the drainiage basin cycle an open system.) Make sure you know what inputs, outputs, stores and flows/transfers are.
The Wycombe High School Geography Department have an excellent set of notes - they don't do the same specification as us, so not everything there will be relevant to you, but it is worth you having a look at the Drainage Basins as Systems and The Hydrological Cycle notes. The Drainage Basins one has a quick test for you to do to check all those key words!
Remember, there are lots of key words to learn - you are much better off learning them as you go along, rather than panicking in summer!
