It was Valentina Tereshkova!
Joanna's group won first place for their grade in an improv acting challenge. They had to act out a 5 minute skit with some inputs and 2 minutes planning. They were given their Cultural treasure was the sun sphere. Their setting was knoxville. Their characters included Leif Ericsson and Juliana Jorkovavitch(sp). Something about the resolution was using a riverbed. After they planned, they got to see their surprise thing. Theirs was ducks taking over the world.
They acted out a skit that was pretty entertaining.
