The document summarizes a study conducted by two students to determine how many personal items are left behind each day at their school. Over the course of a week, they recorded the number of lost items found each day at specific locations after school. Their findings showed that on average 3-6 items were left behind daily, with a total of 23 items lost over the one-week period. Based on these results, the students concluded that many students lose items frequently, and the lost and found collection at the school may need to be larger to accommodate the number of lost items.
