For teaching an testing the drainage basin cycle. Focus on key terms and their meanings and how they fit together on the diagram. Very versatile resource that I have used from KS3-5 but originally designed for KS4. Great for low stakes testing, revision etc. Differentiated resource allows challenge at a range of levels. I give out the key word sheet face down, ask students to complete as much as they can without it and then turn over the key word list to help them when they are stuck. Really high quality resource - print out the sheets and hole-punch them for folders or stick into books.
