The UCSD Bioengineering graduate society will host a hands-on activity for K-12 students about stem cell differentiation. A groundbreaking UCSD study has shown that stem cells differentiate based on the material properties of the surface that they are on. Students will blindly feel into many boxes to feel the material properties of different materials and guess what a stem cell would differentiate into if on that material. There is then an arts and crafts section where students can make their o
