Shiga-like Toxin is made of […]

Protein Models as tools for STEM Education

We’ve known college students enjoy using protein models as tools for STEM Education and learn equally well from both computer-aided molecular visualization software as they do physical models. Could the same apply to gradeschool children?  How young of an audience can we communicate basic molecular biology?  In doing so, can we raise basic science literacy at a young […]
