Lesson Plans
  • Railroads Change Florida: Henry Flagler in Florida # Henry Flagler was the founder of what became the Florida East Coast Railway. During the 1880s and 1890s, Henry Flagler expanded train lines through Jacksonville and down the East coast to Miami. Henry Flagler began the Oversea Railway in 1906 to connect Miami to Key West. This ambitious and innovative project required money, earth-moving, man-hours, and miles of bridges. In this lesson students analyze a letter from Henry Flagler to learn about about Flagler and his contributions to Florida.
  • Florida in the Civil War: Risking Their Lives for Salt # With the seemingly limitless supply of salt available to us today, it is hard to imagine the hardship imposed by its lack. The Confederate army's meat supply was preserved with salt. With the Union blockade in place, the Confederate states turned to local sources for this important mineral. Salt production became a crucial endeavor for citizens of Florida. In this lesson students will compare Confederate and Union perspectives of the salt works using an illustration, a letter and an excerpt from a memoir.
