This is something I used to do with my freshmen peer students in their first year seminar. I created a scavenger hunt list and asked them to go around and take a picture of a member of their team in front of/with/at the location or person. For each type of picture there were a certain amount of points available. The team with the most points would win a prize.
Take this idea and adapt it to your experience. Even if there isn’t a prize being awarded, think about all the memories you’ll have to look back on.
So take a picture. It really is worth a thousand words.
