I'm heavy into Project Based Learning and love to give students an opportunity to express their learning in a variety of ways. Once we completed the life cycle of a star (and heavily went through all stages), students created something unique to show their learning. And boy, they didn't disappoint.
This project is introduced at the beginning of the unit so students have time to create ideas and sort out thoughts. Have a day of celebration, as many will come with a variety of formats. Over the three years I've done this, I've had students create movies using their dogs (different sizes) dressed up as the stages, I've had dance interpretations, rap songs, slideshows, etc... It's really amazing what the kids come up with.
