Milk Science Experiment

Satisfactory Essays

My science experiment has 3 different results but there was only one that matched my hypothesis. After applying all my steps to the soda, when I put it through the strainer the soda completely went through the strainer; there was nothing left behind. Later after applying all my steps to the juice. i also put it through a strainer and i ended up with the same result as the soda. The only liquid i didn't get a bad result for was the milk. The milk went through the strainer and left behind this white squishy looking material. It looked almost as if it were some type of white goo.

With my science project i gained a greater understanding on how vinegar can create a chemical reaction so quickly when working with other liquids. I learned that the lumps left behind in the strainer from the milk are actually called “casein”. The individual protein strands within the milk and the vinegar combine to make the solid, also known as a polymer molecule strand. The globs are made of fat minerals and the protein.. The combination of heat and vinegar (acetic acid) helps to pull out or precipitate the protein casein from the milk. In fact, this plastic is environmentally friendly because it will eventually decompose, unlike plastics made from petroleum products. …show more content…

I really enjoyed making a hypothesis about what was going to happen when the mixture of milk and vinegar was heated in the microwave. I also enjoyed being able to test my hypothesis to see my accuracy. Being able to see the progress within the matter of minutes was incredible to me, i couldn't seem to wrap my head around that. overall my science experiment was
