Colour Changing Milk Experiment

 

Colour Changing Milk Experiment

What happened... Milk is mostly water, but it also contains vitamins, minerals, proteins, and tiny droplets of fat suspended in solution. Fats and proteins are sensitive to changes in the surrounding solution (the milk).

The molecules of fat bend, roll, twist, and contort in all directions as the soap molecules race around to join up with the fat molecules. During all of this fat molecule gymnastics, the food coloring molecules are bumped and shoved everywhere, providing an easy way to observe all the invisible activity. As the soap becomes evenly mixed with the milk, the action slows down and eventually stops. This is why milk with a higher fat content produces a better explosion of color—there’s just more fat to combine with all of those soap molecules.

We were learning about... Colour changing Milk

I found it easy to... mix in bow

I found it hard to... choose the colour of the food colouring 

Next time i will... add more colour
