I read the book An Illustrated Timeline of Transportation.
Students generated a list of transportation through time and I charted their list. Then students chose a type of transportation, drew their choice and we found the inventor and the date of the invention on the internet. We then made a class timeline of transportation.
I collected as many books on transportation and inventors of transportation as I could find in our library and in my classroom collection. I had digital resourses through Pebble Go and my Transportation Wiki.
Students chose a topic. At first I planned to keep the topics limited to inventors of transportation but as the students began talking about what they were interested in learning about, I realized I needed to open topics up to anything having to do with transportation. I'm so glad I did because students chose everything from Amelia Earhart and Henry Ford to How an Airplane Works and Trains Through History. WOW!!
