Milk Lab

We did in an experience in science class on what would happen if you took 2% milk, food coloring, and dish soap? What we found out was interesting things that happen to the milk when mixing some food coloring is the dye made circles in the milk and then would expand except for yellow. Then we would add dish soap just a drop and amazing things happened.

Figure 2: Milk, food coloring, and dish soap

 As you can see from the figure 1 the milk allowed the dye to form a circle for each color. It did not mix any colors together. As you can tell from the picture this experiment was interesting from the start but wait till it gets to the dish soap being added.




As you can see in figure 2 when adding the dish soap it made the colors blend together a little more. When there was no dish soap you can see the colors as plain as can be. Once we added the dish soap into the dye mixture and milk it makes like a star figure. The dish soap chemicals go right through the dye to separate the colors.

As we let the dye and soap sit for awhile we came up with an interesting mixture it was super unique to see the mixture change.

Figure 3: Mixture is changing

 As you can see from all three figures it was in interesting an unique concept that allows all students to see and react just like we did.
Next, I will show you some pictures of how we changed a few of the things and what they did differently was just WOW....

 We tried four different experiments with different milk. We used 2% milk as shown in the first three pictures. We also did one with Fat Free Milk, Whole Milk, and Half and Half Milk. In the last experiment with the milk we did Whole Milk warmed up in the microwave for about 15 seconds. We then pour the warm milk into the dish and added the food coloring. It did the same thing with color separation but when we added the dish soap bigger things happened. In the warm milk it kept on working longer than the regular cold milk.

As you can see we had a great time being able to experiment with different kinds of milk. That each milk told a different story. If they were cold milk they did something different than warm milk.
