Rube+Goldberg+Machine+Project

Transformers In groups of three, and using the kit provided, you are to create a machine that will pop a balloon. In your kit, you are provided with a range of materials and your final product must include __at least__ three simple machines. A prize will also be given to the group out of each class who construct a machine which is the most creative. (This will be decided by the teacher and your score in the rubric below.) We could then have a "machine off" at a lunchtime between the three classes.

__Your machine must;__
-Mechanically pop a balloon -Be constructed on two tables (although it can come off the tables also). -Have at least three simple machines that activate each other -Be started by a small push or pull and then run on itâ€™s own

After each session, you will need to be able to pack your pieces into the tub provided. On the final day, you need to present your project to the class, naming the simple machines within the construction and then demonstrating your project. You will also be given an assessment sheet to assess yourself.
