Think about all the project you've done this year: Perfect Pets, ChibiChip projects, automata, puppets, kaleidoscopes, exploding books (map of me), etc.
Which one of these would you like to try again?
How could you improve upon what you did before?
What can you add/change to make it more intersting?
How might you combine elements of 2 projects into something new or different?
How might you take the techniques we used and apply them in a new way?
Write Mrs. Bisson an email explaining which project you'd like to retry, the materials you'll need, and how you are going to expand or improve on the old project.
