This resource guides students through the experiments conducted from the 1930’s onwards to disprove the Davson-Danielli model of the cell membrane. There are two versions of the student sheet so the task can be fully differentiated. Comes with a teacher mark scheme.
The space at the top of the exercise I would advise having the following text to support learning:
The Phospholipid Membrane
Something went wrong, please try again later.
It has details of the history and scientists. The questions are not that challenging. The sheet is better off if you are teaching the fluid mosaic membrane and need one task.
