Brief Project Description (?)help other teachers decide if this project is something they can do, please briefly indicate the equipment and materials they'd need to do this project. For example, you might need a mill, lathe, protractors and 4x2x0.25 pieces of aluminum for each student. Note that you can attach detailed material and equipment lists below.

Students will use the “Produce Design Model” to develop a delicious candy bar. Students will be given the design specifications for the candy bar, which will allow for maximum sizes and criteria to evaluate the finished product.
