Ethan De Leon, 13, Kaprie Gonzalez, 14, and Joseph Mimun, 14, check out a pig lung attached to a foot pump on the ground at a biology information table Wednesday during the STEMulate science showcase in the mall. Gonzalez noted that a pig lung is similar to a human lung and “noticed that it only takes one breath for it to expand fully,” during the event sponsored by Adelante Tejas. Photo by E. David Guel
