Wilson and Young Middle School seventh grader Kayla Chung, right, reacts to being told by Greg Gage she just volunteered to pickup a cockroach and put it in a bowl of ice water to sedate it during a Backyard Brains presentation Thursday afternoon in the Odessa High School Performing Arts Center. The cockroach’s leg was removed after being sedated so that students could observe the transmission of neurons. Greg Gage is the co-founder and engineer of Backyard Brains.
