We did two demonstrations

First we took notes on hydrophilic and hydrophobic soap, and phospholipids.

The cell membrane

-       Is made of protein and fat. 

-       The membrane is a bilayer of phospholipids. This means there are two layers.

-       The phospholipids are made of a phosphate and a lipid

-       Lipid=fat.

-       Lipids are HYDROPHOBIC  , water hating

-       Phosphate part is  HYDROPHYLLIC

Water- loving.

Proteins are scattered in the membrane and they

assist the cell  to

Allow things in and out. 

Lab: A demo of hydrophyllic and hydrophobic properties of three substances.

Substances:

1.      Soap – has two sides.  One is hydrophobic and the other is hydrophyllic

2.     milk –is a suspension of fat droplets suspended in water.

3.     food dye -  loves water.  Hydrophyllic,  

We added drops of food dye to milk and then we added a drop of soap  Next, we wrote our observations and hypothesis.  The teacher evaluated the hypothesis.
