If you were teaching students remotely online, one example of a data collecting activity they could do would be to have them find out the number of COVID-19 cases their state/country has every day for a week/two weeks. They could then turn this data into a graph (integrated with maths), which could then open up discussions surrounding data collection (what they found, comparing with classmates etc.) as well as learning about how COVID-19 is affecting where they live.
