This is awesome:

Seventh graders were asked to draw a picture and write a description of a scientist.

 

After doing so, their class visited Fermilab. Following their visit, they were asked to draw another picture and write another description.

 

It makes for quite the juxtaposition... as you might be able to guess their perceptions were radically altered by real-world interaction with scientists, rather than what the media and movies have always told them they were supposed to believe scientists were.

That seems a little bit fake, but the concept is interesting. I do enjoy this one though.
