This Friday we had to do science at home. We were learning about chemical and physical change. A chemical change is when its a new substance it is a entirely new thing. But a physical change is when nothing changes about the object, like ripping a leaf nothing changes about that its just ripped.
We had 4 options of experiments we had to do, we could do one or multiple. I picked the last one it was titled color changing milk and the milk changing wasn't the main subject. it was how soap works.

I have images I took on my phone to describe what happens.
the ingredients are: dish soap, plate, milk, one or more colors of food dye, milk and a cotton swab

step one add milk onto the plate.
step two add one drop of each color in the center if you add to much it is o.k
step three add the soap to the cotton swab.

step four last but definitely not least put the cotton swap where in the center of the milk and if you have it like this just mix a little bit and then dip it in.

all of this is a chemical change because

milk is formed of mostly water but it does contain vitamins, minerals, proteins and tiny droplets of fat. The fat and proteins are super sensitive to changes within the milk and then when the dishwasher detergent is added a chemical change occurs. The soap and fat work flat out to hitch together, which causes the movement. When coloring is added we are ready to witness this chemical change occurring - the colors begin to spread faraway from the dishwasher detergent drop and start mixing and churning the colors.
