From 2016, my most recent trip. This was from the time my daughters and I were doing the "All Park Challenge." We started the day in Typhoon Lagoon, then went to each of the four theme parks in the same day. The rule was we had to do at least one attraction in each park for it to count.
We did the Railroad in Magic Kingdom, Dinosaur, in Animal Kingdom, The Great Movie Ride in the Studios, and Innoventions in Epcot. We think Innoventions may have been a bit of a cheat, but Disney calls it an attraction, so it probably counts for our purposes.
