2018 revision

The Student Handout has been entirely revised, with expanded explanations and questions concerning the molecular structure of cell membranes and how phospholipids and proteins combine to form the selectively permeable cell membrane. We have added a second experiment which demonstrates how a layer composed of nonpolar molecules can form a barrier to the diffusion of ions. Also, the Student Handout now includes a brief introduction to endocytosis and exocytosis.
