1. To See or Not to See? Hydrophobic and Hydrophilic Surfaces

   03 Dec 2020 | | Contributor(s):: Jenny Willis, NNCI Nano

   This activity can be completed as a separate one or in conjunction with the lesson Superhydrophobicexpialidocious:  Learning about hydrophobic surfaces found at: https://www.nnci.net/node/5895. The activity is a visual demonstration of the difference between hydrophobic and hydrophilic...

2. Superhydrophobicexpialidocious: Learning About Hydrophobic Surfaces

   06 May 2020 | | Contributor(s):: Jenny Willis, NNCI Nano

   This is a two-part lesson. In Part 1, the teacher will choose one of two lessons on hydrophobic materials. These lessons let students experiment with materials that have used chemicals to create hydrophobic materials. In Part 2, students will use pieces of Teflon to physically create a...

3. The Water Race: Hydrophobic and Hydrophilic Surfaces

   23 Jan 2020 | | Contributor(s):: Alondra Droege, NNCI Nano

   This high school chemistry lesson provides an introduction to the engineering of an interfacial surface at the nanoscale. It demonstrates concepts of hydrophobic and hydrophilic behavior. Students will create (through chemical reactions) a hydrophobic and hydrophilic surface using a 2 nanometer...

4. Exploring the Properties of Magic Sand

   13 Jan 2020 | | Contributor(s):: Amy Brunner, Nancy Healy, NNCI Nano

   This lesson uses a hydrophobic material called Magic Sand to: 1. Explore the properties of molecular bonding; 2. Introduce students to the engineering of hydrophobic surfaces; and 3. Demonstrate the concepts of hydrophobic and hydrophilic behavior. It is suitable for high school students in...
