From earthworm farms to smoothie-making bicycles, Farm City Day teaches students about their food, from the farms to their forks.
Farm City Day is put on annually by the Shasta County Farm Bureau, a non-profit advocacy group for farmers and ranchers.
"What we do here is we invite all of Shasta County's fourth grade students to the fairgrounds, and we teach them about agriculture," said Shasta County Farm Bureau Manager Tiffany Martinez.
The Farm Bureau believes that it's important to expose students at a young age to the role agriculture and animals play in their daily lives.
At the end of the event, each classroom is sent home with a bin of educational materials so they can continue to learn about agriculture at their schools.
