Learners investigate Nanotechnology. In this physic's lesson plan, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Learners 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. Learners will explore and discuss many aspects of Nanotechnology.
