I created this edible "phospholipid bilayer" activity to help my students remember the structure and key parts of a typical cell membrane. Each student receives a snack bag with 8 marshmallows, 2 two inch sections of pull peel licorice, and 1 four inch piece of a red vine licorice (I used grape flavored red vines this year as the "Purple" transport "Protein".) After completing a worksheet about the functions key parts of a cell membrane, we each assemble one pair share about each part. :)

FREE Osmosis/Difusion Lab
Cell membranes and the transport of materials across membranes is fundamental to a study of biology. There are, fortunately, many good lab activities that can be carried out when covering this material. My students just finished doing this lab today. It is called "The Effect of Concentration on the Rate of Diffusion", and you can download my version of this lab for free. The concept is very simple. First, the students fill dialysis bags with varying concentrations of sugar solutions. The…
