premise: The zucchini and bean plants grew to over 4 inches by the third week , and the kids would run in and track the progress of their plants each day , balancing precariously on a chair so they could see better . It was nice . Even the staff at the school where we were running the program became interested in making their own , so I gave them some soil and seeds as well . Why would the kids run in and track the progress of their plants each day ?
hypothesis: Because they are zucchini plants .
