The purpose of this slide deck is to guide students in the process of constructing the proper apparatus necessary for performing a cell membrane simulation using soap bubbles.

I am a high school biology teacher and this was a lab we did in class.

My students loved it!

900ml of water
100ml of dish soap
25ml of corn syrup
four straws
shallow tray
roll of thread
ball of string or twine

The ring of thread is used to create a channel through the bubble film. The frame is lifted from the tray of bubble solution so that a thin film spans across the frame. Students gently lay the ring of thread onto the bubble film. The students then take something dry, like the tip of a pencil, and pop the film inside the ring. To their amazement, the string pops into a perfect circle that floats across the film within the frame. This is used to illustrate channel proteins that create passageways across cellular membranes.
