Cosgriff-Hernandez Laboratory

                             


MIDDLE SCHOOL SCIENCE CLUB

Every month, graduate and undergraduate students from our lab travel to College Station Middle School to do hands-on demonstrations for Maryam Ahmed's 7th Grade Science Club. If you are interested in the materials or protocols that we use, please contact Dr. Cosgriff-Hernandez for more information.
