Warrick County schools bussed in some 450 4th graders to see exhibits about dozens of different counties. Those exhibits were created by high school students.
It's all in an effort to teach the younger ones about cultures, languages, and traditions from around the world.
"I just think it's really important for them to know," said Castle High School Spanish teacher Anette Scott. "Otherwise, they just think they are in their own little world. It makes them more global citizens. They really enjoy it. It's also good for them to interact with the older kids, and they can see the older kids setting a good example for them."
There were also exhibits about world currencies and five of the world's major religions. Organizers say they spend all year planning this event.
