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.
