The other half is spent inside the activity room where they explore things like little scientists. On their first day, their lesson was about hot and cold and they "discovered" that ice turns to water when subjected to heat (or fire). Gabbie knows this by heart already.
On the second day, they talked about wind and learned that some things can be moved by wind- like clouds and windmills. They made a pinwheel which she later used in the fountain area of Eastwood City and she was really amazed that it indeed moves like a fan when there's strong wind.
