Students investigate Nanotechnology. In this physic's lesson, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Students weigh chocolate syrup to determine it's wait in grams, and then measure pretzels in centimeters.  After dipping the pretzels in the chocolate the students reweigh and remeasure the items. Students will explore and discuss many aspects of Nanotechnology.
