Im babysitting starting tomorrow, its my cousin. What are some crafts, and stuff we could do?

I have a 9-year-old girl. She likes to color, paint, work with clay, make things from recyclables, or do any kind of craft. She likes to help cook. She likes to play outside, climb trees, look for frogs or bugs, ride bikes, or play tag or hide-and-seek. She likes to play card games and board games. She likes to build complicated structures out of blocks (she particularly likes making regular wood blocks into marble tracks). She likes to dance to music. She likes to make elaborate forts out of pillows and blankets. She likes to read. She likes to write and illustrate stories.

Depends on the gender. Boys like sports, so maybe you can do a sport-themed craft. Girls will go with anything you throw at them, as long as it's not too boyish.
