There were showers during a sunny Tuesday morning in Davenport.

That's because engineers from Iowa State brought a rainfall simulator to Davenport West High School.

Science students got a hands-on lesson about soil erosion.

"It's just interesting to see how it has a real-life application with what we're learning in class," said Davenport West senior Nicole Kraft.

Students got to see how different land practices can worsen or improve soil erosion.

"In about 20 years, we lose an inch of top soil," Kraft concluded. "It takes about 500 years to grow one inch back."

Iowa State educators make more than 100 appearances with the mobile rainfall simulator each year.
