Exploring Cell Membrane Properties Through Bubbles

Why are bubbles used to demonstrate the properties of the cell membrane?

• Because they are easy to make

• Because they are fun to play with

• Because they are colorful

• Because they share similar characteristics with cell membranes

What is the structure of a phospholipid?

• A water-hating head and two water-hating tails

• A water-loving head and two water-loving tails

How do the heads and tails of phospholipids behave in water?

• Both heads and tails love water

• Heads love water, tails hide from water
