Time to Experiment!
-
Fill the shallow bowl with milk so that it covers the bottom of the bowl-not very deep.
-
Put a couple of drops of food coloring on top of the milk.
-
Have your child(ren) carefully dip the cotton swab into the dish soap-making sure it is covered all the way.
-
-Ask your child(ren) to predict what will happen when they dip the cotton swab into the milk.
-
Have your child(ren) carefully touch the top of the milk with the cotton swab.
-
Observe what happens!
-
*Explain that this works because milk contains a lot of protein and fat-the dish soap makes these two separate and spread. The green food coloring shows this!
