There are loads of ways that you can use Excel in Geography. Here are a couple of more innovative uses:
Pollsters (click the image below to download the pollster). I can't claim that this is my idea, but I'm not sure where I originally saw it so I can't credit anyone else either. I make loads of Pollster sheets as they're a good background activity for use in class. You can type pretty much anything into the sheet and then carry out a poll during the lesson. Try using this idea alongside some clips from the BBC Video Nation website where people record their views on just about anything. This pollster asks students what type of economic activity their parents are employed in. I use this with KS3 - you can choose a much more controversial question to use with KS4 and 5!
Gameshow Geography (click the image below to download the gameshow file). I made this scoreboard for use with classes doing end of term quizzes. The classes get much more involved in the activity as they can follow the scores better. You can type individual team names into this spreadsheet and they will appear under the graph. I've also put a countdown timer in the top right of the screen for authentic gameshow effect!
