Review questions:
- What are the types of molecules that are in milk?
- Are detergent molecules charged? (negatively charged, positively charged or no charge)?
- Why did the colors move in cool ways?
Deeper understanding of charged molecules:
-The negative end of the detergent molecules line up with the positive end of the water molecules.
-This causes the detergent molecules to zoom out in every direction over the surface of the milk and push the food coloring outward
-The negative charge on the detergent molecules are attracted to the positive parts of the protein molecules
-The uncharged part of the detergent molecules lines up with the uncharged fat molecules
