A great culminating activity for an Ecology unit. I use it after the End-of-Course test at the end of the year. It's a fun activity to get the students outside after testing is over. I used the activity at school. We walked around the campus and students were allowed to use their phones to take pictures and upload them to Instagram. However, students could find objects at other locations, as well. They were required to state where they found the item, though. Teachers may use discretion on this aspect of the assignment.
