SALEM TOWNSHIP -- Some boys and girls in Wayne County were a little surprised on Tuesday to learn that their food doesn't only come from the grocery store or restaurants.
A special classroom on wheels stopped at their school on a statewide mission to teach children about agriculture.
"We're going to be tasting juices to see what's better for us."
It was a day of experiments involving agriculture at Evergreen Elementary School near Hamlin.
The Mobile Ag Ed Science Lab is here all week. Thanks to the Pennsylvania Farm Bureau, it travels the state teaching kids the values of farming.
The third graders were doing some taste testing. The goal is figuring out what drinks that claim to be grape really are made with grapes, and learning that grapes that make actual grape juice are grown, some even here in Pennsylvania.
"I think it was a great opportunity for me to learn that food doesn't just come from the grocery store," said third grader Mackenzie Adams.
"That's what I thought before!" said third grader Kayne Bihler.
"That's the point of this, there's so much of a disconnect because there aren't as many farms anymore," said Cathy Vorisek, Mobile Ag Ed Science Lab.
The boys and girls also learned that what tastes good may not always be good for them.
"And I thought it was really cool because it was like we had soda in school, and I was like, 'yes, soda in school!'" said third grader Kayne Bihler.
"But did you learn that's the best for you?"
"No," said Kayne.
The students learned not only are grape soda and grape Kool-Aid not the healthiest choices, they don't even have grapes in them.
But 100 percent grape juice lost when it came time to vote which one tasted best.
"I liked the grape Kool-Aid the best," said Freddie Leonetti.
"My favorite was grape soda," said Lareina Tirado.
"Was that the best for you?"
"No."
"Because it has a lot of sugars and it's zero percent juice," Mackenzie added.
"It's fun to watch the kids, their eyes light up when they realize something," said Vorisek.
And all week, students at this school will be realizing agriculture plays a big role in their lives.
