I was interested in which National History Day themes tended to generate STEM-related or arts-related projects. I had access to the full lists of national contest entries from 2016-2018 and the lists of finalists from 2011 to 2018. This post focuses on STEM-related projects.
The number of STEM projects at the national contest and in finals varies significantly from year to year, and it seems very tied to the topic. Topics that focus on the impact of a person or event (such as "Turning Points" or "Revolution, Reaction, Reform") lend themselves to STEM topics. The most common fields for STEM projects across years are medicine, environment, and disease, with space, nuclear, and other biology topics also common. This might be because of accessible resources on those topics or earlier exposure of students to them. No NHD category consistently has the most STEM projects, but performance often has the least.
Below the fold are more details on what I found. There are some notes/disclaimers about this analysis and how I categorized projects at the end.
