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!
