A quiet new student named Jack has joined Rosie and Wolfie's table just in time for a group project. They must use the scientific process to see which team can grow the tallest bean sprouts. Rosie is eager to make a new friend, but Jack doesn't talk to her, and he seems to have a different idea about "teamwork." Then Jack helps Rosie discover that there's more than one way to do a science experiment - and more than one way to be a good friend.
