This is a lesson plan that explores how nanotechnology has impacted the world. It was developed to help students visualize just how tiny a nanometer is and how scientists work to apply principles of nanotechnology. In hands-on activities, students evaluate and compare the surface areas at the macroscopic and nanoscale level. Links are provided to images of nanoscale objects produced by scanning electron microscopy (SEM). In the culminating activity, learners prepare a mock proposal for funding a
