What is Materials Science? What's materials science? You could call it the study of stuff! Just about everything you use every day - the shoes you wear, the dishes you eat from, the music you listen to, the bike or skateboard you ride - it's all made of different kinds of stuff. Understanding how that stuff is put together, how it can be used, how it can be changed and made better to do more amazing things - even creating completely new kinds of stuff: that's what materials science is all about. Explore materials with these fun activities!
