(AP) — More than 1,800 students from about 20 school districts in Nebraska got to spend a day at state parks as part of a program aimed at exposing kids to the wonders of the parks. Trout eggs arrived in the classroom in January, and Settles' second-graders spent four months tending them, feeding them, cleaning their aquarium and monitoring their growth. Settles said the trout project is a way to teach students about the food chain, life cycles and how everything is connected.
