Review by by Helen Gardiner van de Pol
As science communicators, we are always being asked to evaluate our activities and demonstrate impact. Teachers know this well. How do you know which part of what program helped form the adult you see before you today? That science outreach event you planned for 8-9-year-olds some 20 years ago, did it impact those children as intended? Did it contribute to their later decision to choose a career in science? Did it make them more scientifically literate even though they grew up to do art? If we interviewed them today, would they correctly recall your wonderful program and describe how it changed their life or would it just be part of a fog of memories which included fun trips to the museum with their favourite aunt who was a scientist?
