About 160 area students toured the U.S. Department of Energy's Technology Laboratory Wednesday as part of President Obama's Brother's Keeper initiative to address opportunity gaps in science, technology, engineering and math fields.
Students were encouraged to pursue those fields with hands-on activities, such as experimenting with liquid nitrogen and testing acid voltage of fruits and vegetables. Researchers also talked to students about the lab's work in energy and environmental research and development with the focus of providing clean energy.
The lab was one of several national labs to host a lab tour day.
