First-graders experience sound and light day

Demoney Elementary first-graders heard a lot of sound and saw a lot of light during sound and light day Thursday.

Emmet County Conservation Board naturalist Jenna Pollock showed students some of the fine, feathered friends they might see in the great outdoors while Alan Morphew demonstrated the science of sound.

One of the biggest thrills came when Brian Scott, Iowa Lakes Electric Cooperative foreman for Estherville and Swea City, gave their teachers a 60-foot-high ride in the bucket - sort of a sideways Ferris wheel, if you will.

Scott first showed how electrical workers put on rubber gloves and sleeves for protection and use a fiberglass insulated stick to open up lines.

First-graders then had some pretty valuable lessons in electricity - like not playing around electrical boxes.

Later Larry Walthart, also from Iowa Lakes, showed students a model with electric lines in the Little Theatre in the high school.

Walthart told the kids how aluminum and copper conduct electricity, and that's why we need to be careful with aluminum ladders around electricity.

"After you touch the wires it's already too late," Walthart said, adding that trees can conduct electricity as well.

Even kites can be dangerous around electric lines - meaning you don't have to be like Benjamin Franklin and wait for lighting to string.

"Even a string can carry enough electricity to shock you or kill you," Walthart said.

And if electric lines are underground, we need to call before we dig. A locater service will come and mark where various utilities are located.

Around the house, it's a good idea to keep little brothers and sisters from sticking things like forks, knives or paperclips into outlets, Walthart said, adding that you can buy plastic caps to cover outlets.
