Will the type of milk affect the mass of the plastic? Aim: our aim is to investigate will the type of milk affect the mass of the plastic? The types of milk we will be using are: low fat milk, soy milk, whole milk, coconut milk, semi-skimmed milk, condensed milk. Every time we will be changing the type of milk to see if the plastic changes, for example if we get heavier plastic or lighter plastic or even any plastic at all. To the milk we will always be adding 15ml of vinegar. The way the plastic is formed from the milk is, the casein from the milk hardens into plastic that can be painted with acrylic paint. Casein is used to make plastics, adhesives, paints, and foods. Casein is the name for a group of proteins found in milk that are also used to make cheese. Casein is mixed with other ingredients to make a type of plastic that's used for buttons. It is extracted from the proteins of the milk: in the milk, casein is structured in voluminous globules. These globules are mainly responsible for the white colour of the milk. According to various species, the casein amount within the total proteins of the milk varies. A globule is like a big blob of something gooey that can repeatedly change shape in the air. As different milks contain different amounts of casein this can affect how big the plastic is or even the colour the plastic will be. Dependent variable: The same amount of milk used all the time- we need to do this as if we change the amount of milk used all the time then we will get unreliable results as the weight could change due to the amount of milk used. Same type of cloth for straining- we need to do this as if one cloth has larger holes than the other then the water could go through and unnecessary of the mixture could go through and have an effect on our results. Same vinegar- if we use different vinegars they could be stronger than the other one and
