Lighthouses are pretty big here in North Carolina, so I did a little research project with my 4th graders who study information about the state all year long. First we watched this short video about the 7 lighthouses in our state, it is about 8 minutes and is a pretty good intro to our lighthouses.
I gave each student a graphic organizer and had bookmarked a couple of good sites with information about each lighthouse on our Destiny homepage for them to use. They found some basic information about each lighthouse including location, pattern on the lighthouse, light pattern at night, year built, etc. Then, they compiled this into an illustrated flip book showing each lighthouse that the teacher used for a social studies grade in the classroom.
