 * __ DIY Plasma Membrane Paper Model!! __**

Step 1: Color the parts of the model according to this guide. You will need PINK, YELLOW and BLUE.


 * Color the circles of the KEY Blue for + positively charged (polar), Yellow for neutral (nonpolar) and Pink for – negatively charged (polar)
 * Color all of the WATER MOLECULES according to the key (H’s + Blue, O’s – Pink)
 * Color all of the CARBOHYDRATE CHAINS (polar) by alternating Pink and Blue
 * Color the three TRANSPORT PROTEINS by region (+ Blue, N Yellow, - Pink) stay in the lines!!
 * Color the PHOSPHOLIPID BILAYER sections Pink and Yellow(- polar heads, neutral nonpolar tails)
 * Color CHOLESTEROL Yellow

Step 2: Cut out all of the phospholipid groups (do NOT cut out individual phospholipids!) and the proteins. Align across a blank sheet of copy paper (hamburger layout) according to CHARGE. All NONPOLAR regions should be in the middle of your line of molecules and all POLAR regions should be to the outside. Be creative!!

Step 3: Raise your hand and compare your plasma membrane model to a sample image. **When approved, glue it down.**

Step 4: Cut out the remaining WATER MOLECULES, CARBOHYDRATE CHAINS, KEY and EXTRACELLULAR AND INTRACELLULAR LABELS. Proceed to place these items in the correct locations as best as you can. Raise your hand for approval.

Step 5: Glue down the remaining parts. Add your names to the model and turn in.
