Show off your artistic side as well as discussing solvents, diffusion, and movement of molecules! Students will make their own t-shirt designs that are permanent and beautiful. This is a fun activity that students will always remember. I lead this activity just after our properties of water lab that demos chromatography, but it could fit in later when discussing diffusion as well. I have my students wear their shirts on test days for a bonus point for extra fun - it is a great "class bonding" activity! This handout has everything you need to jump in... just add shirts, sharpies, rubbing alcohol and some creativity.
