How does the map show how peopleвЂ™s lives have changed over time? (It shows increased transportation, including commuter train lines, and also more roads and bridges for car/truck travel instead of ship/boat travel.).Why do you think Bostonians filled in the water around the original city? (Possible response: as the population grew, there was a need for more land.).Students likely do not realize water could be filled to become land. Compare their ideas for how the area might have changed. Have students come to the map and describe the differences. Give students a few minutes to examine the map and list on paper ways Boston has changed since 1775. Project the map titled Boston Now, and point out the lines that show the original shoreline. Ask: What physical changes could have happened? What human-made changes could have happened? Invite students to come to the projected map and describe their ideas.ДЈ. Why do you think Boston was settled on a peninsula? (Possible responses: the settlers wanted a place that was close to water for ships but also easy to defend from attacks access to Boston via the narrow connection to the mainland was easy to protect.)ДЄsk students to imagine how this area may have changed over time.What landforms do you see? (The city was a peninsula the Charles River flowed into Back Bay.).Have students describe the land and water they see on the map. Ask: Does this show what Boston looks like today? How do you know? (No the date on the map is 1775.) Explain that we call a map like this a historical map, because it shows what the land was like at a particular time in history, or it reflects what people knew at the time. What are some examples of physical changes affecting a place? (Possible responses: rivers can flood shorelines can change and volcanoes and earthquakes can affect a place.).Are there physical changes that have affected the area? (Explain that human changes are often more visible, although physical changes affect a place over time too.).Are most of these changes human-made? (Yes.).What has changed in our community in the last five years? (Encourage thinking about new roads, shopping or business areas, housing developments, and areas for recreation.).

Have a whole-class discussion about how land use has changed in studentsвЂ™ community over time. Focus on changes in studentsвЂ™ community over time.
