Make Plastic From Milk
In this captivating chemistry experiment, we'll explore how heat and acid affect milk protein casein. By heating up milk and adding vinegar, the casein separates, creating a moldable plastic-like substance. Try this hands-on experiment to witness milk transform in an unexpected way!
The hypothesis is that heat and acid will cause a reaction in milk proteins.
Method & Materials
You will place skim milk in a pot, add vinegar, heat, and stir until lumps form. Then filter the solid from the liquid, add water and baking soda, and observe the results.
You will need skim milk, a beaker, vinegar, a heat source, baking soda, a funnel and filter paper, a stirring rod, water, and a graduated cylinder.
The heat and acid changed the properties of the milk. We observed a precipitation reaction and a neutralization reaction, which changed the milk from a liquid to a plastic-like substance.
Why do this project?
This science project is interesting and unique because it uses everyday items to create an unexpected plastic-like substance that can be molded into different shapes.
Experiment variations to consider include using different types of milk (lowfat, whole milk, almond milk), adding different amounts of vinegar, and cooking the mixture at different temperatures.
