The webquest offers connected lessons with student and teacher materials investigating the events happening at the time of the first Thanksgiving, or the harvest festival of 1621.
The Plimoth Plantation offers a great resource for students on their website to help students become historians and analyze account of the Native Americans and the Pilgrims.

I made these materials to help my 5th grade students navigate the website successfully.
I also made a PowerPoint presentation, "What is History," describing primary and secondary sources. I refer to that Powerpoint in these materials. If you are interested in the PowerPoint it is also available in my store.
I currently teach reading and support expository reading instruction in social studies at the 4th and 5th grade level. This activity teaches students to synthesis information to understand the "big picture."
