This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world. Learners will break into groups and conduct a "NanoBlitz Challenge," spending a set amount of time on a scavenger hunt for all things nano, both natural and man-made, in the world around them. They will then assemble a chart of their findings and discuss. Also relates to linked video, DragonflyTV Nano: Where's Nano?
