    Teaching Materials | 17 Apr 2020 | Contributor(s):: Brandi Childress, NNCI Nano

    This lesson uses a macro-model to demonstrate the diffusion of molecules across the cell membrane.  A deshelled egg serves as the cell model to observe movement in and out of the “cell”.  Students will learn that the cell membrane is composed of a complex nano-structured...

  2. Nanoparticle Pollutants

    Teaching Materials | 17 Jan 2017 | Contributor(s):: Darren Hayes, Nancy Healy, NNCI Nano

    Many plastics are in our oceans due to pollution, including ocean dumping and land runoff. Sunlight and alkaline ocean water break these plastics down into small particles, many are nanoscale in size. These nanoparticles can easily enter our cells. Students examine if and how  these...
