On October 3rd and 5th the sixth graders from O'Maley Innovation School explored the Gloucester Harbor Walk.  Using our essential question  "HOW IS CHANGE OVER TIME OBSERVED AND MEASURED' to guide our discussion and exploration,  students completed a scavenger hunt at each of 36 posts found throughout Harbor walk.  We documented our exploration through writing, video and photos.  Students will use the knowledge gained through this experience throughout the year in our project based learning curicullum.
