This is the second lesson of a series of lessons based upon the water and carbon cycle unit (3.1.1) of the 2 year AQA geography A-level (7037). This lesson allows students to become familiar with the distribution and magnitude of the Earth’s major stores of water. It includes several activity sheets that I have created to help develop the students understanding of the Earth’s main sub-systems. There is a fact finding activity where students are given a piece of information on entry to the lesson and they have to use these to complete a headline/summary activity sheet on the major stores of water. There is also a key term heads and tails activity sheet, a summary template that was set as homework where students use their lesson notes and own research to consolidate their learning and some extra reading on water in the lithosphere.
