Students are assigned a country in Latin America as a wrap-up for the social studies unit. I gave them their countries early in the unit so they could jot down notes throughout, but we spent several weeks leading up to the due date doing research. I gave them a research goal each day, and they submitted their notes and a paragraph summary (to later become the database entry) to me on Google Classroom.
I differentiated this assignment for some students by having them narrow their research focus down to three out of the five categories. On the other end, students could go as in-depth with their research as they chose.
