This could link really well into human ingenuity. You could implement some project related to dance, either composing a new dance routine, running dance classes for friends, if you're after a big challenge, look at offering dance lessons to under privileged children in your community as this could link into community and service. You would need to begin researching the skills and knowledge to implement this, carry out the project, ask for critical feedback and then write your report on the process. It is important to remember that the focus of the PP is to go about learning something new independently, not the actual product. As long as you learn heaps, reflect upon the process well and can demonstrate an understanding of how your project fits into the grand scheme of life you will do fine.
