Things to do with a 5 year old

Okay, so tomorrow I am babysitting a 1 year old and a 5 year old, I watch 8 1 yr olds daily so I got that down, but what do I do with the 5 year old lol she's a girl and she's very sweet but I have no idea what to do, I don't wanna just watch movies for 3 hours with her. 1 yr old goes to bed early so most of the time it will be just her and I. Ideas are appreciated!
