Just a suggestion feel free to disregard.
I have noticed an uptick in people new to programming trying their hand at analyzing the raw data counts for COVID-19 and creating graphs, predictions and maps.
The raw data counts can be found at 2019 Novel Coronavirus COVID-19 (2019-nCoV) Data Repository by Johns Hopkins CSSE.
While the COVID-19 counts are useful, when you add current population counts and other criteria for doing calculations you can learn more. e.g. United States County Population by Characteristics: 2010-2018
Also since the data from Johns Hopkins is combining data from many sources if you want more accurate and/or up to date information you have to find such sources. In New Jersey the most up to date and accurate information can be found at NJ COVID-19 Dashboard
What would be interesting to see the class do would be a federated search.
