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 super-hydrophobic surface.  They will use a protractor to measure the contact angle of a bead of water and compare grit size of sandpaper to contact angle.
