This lesson investigates the destructions, resurrections, and transformations of Maine’s largest city in maps of Portland from the Revolutionary War to the beginning of the twentieth century. This visit theme includes a board game in which students must work together to save Portland from the infamous Captain Mowatt, while learning about the important people, buildings, and industries in ‘Falmouth’ during the Revolutionary War.

Intended to be completed in the classroom before the scheduled field trip or class visit, the pre-teaching activity will give students some familiarity with the terms, ideas, and visuals, that they will see during the actual visit.

Guided Inquiry Exercise

During this portion of the visit, students will be asked to look closely at twelve to twenty maps that fit within the curriculum theme. Each student will need to find:

  1. something they recognize from previous class lessons or from the pre-teaching activity
  2. something they find interesting and want to point out to their classmates
  3. something they would like to know more about

Examples of Maps Used:
(sets of maps will vary)


OML visit themes have recommended hands-on activities or group-games that can be done in conjunction with the Guided Inquiry exercise.
