In this experiment, students make "ferrofluid", a colloidal suspension of magnetic nanoparticles. Ferrofluids respond to an external magnetic field, enabling the solution's location to be controlled through the application of a magnetic field. This again highlights to students a change in material properties at the nanoscale. The teachers and students guide to this experiment are available here http://education.technyou.edu.au/view...
