Geo hunt

Gotten the students to do the GI in an amazing race style. I have a total of close to 100 students and did not have enough weather trackers for all the group. Initial plan was to get the students to take turn to go to the five stations which the teacher will pass them the weather tracker at the station. But that would mean 4 groups or 20 students at a station which will be too crowded.
Though some did feedback it is tiring, most enjoyed it and I am really impressed how one group completed in within 40 mins. I did a trail run before that and it took me 1 hr 10 min.  One girl also commented maybe it would be good to increase the number of questions at the QR code station. All appreciated that they managed to learn how to use the weather trackers to collect weather data.
