The formative evaluation of the nanobooks reveals that children who read How Small is Nano? came away with a better understanding of relative size and the nanoscale. Only one in ten readers of Is That Robot Real? mentioned that the message of the book related to size. However, half of the visitors who read the robot book enjoyed it so much and were so interested in the material that they would read it again and encourage others to read it. A majority of the How Small is a Nano? book still found it interesting and enjoyable, but wouldn’t recommend it to others or read it again. Overall, a majority of visitors were more interested in nanotechnology after reading either of the books, and found the vocabulary to be “just right”.
