Milk Lab Regents Chemistry 483 Words | 2 Pages. Milk Lab Purpose: To observe how different fat contents of milk react to food coloring and dish soap. Hypothesis: If we increase the fat content of the milk then food coloring won't spread as fast The bottom of the glass initially has few or no food coloring molecules and so remains clear. As the food coloring molecules begin to interact with the water molecules, molecular collisions cause them to move randomly around the glass. As collisions continue, the molecules spread out, or diffuse, over space. Figure 2: Diffusion of a purple dye. Egg Lab Report Template Finally, the last egg that went through diffusion, the egg left in red food coloring, had a large difference in its mass.
