Earlier this term, 5/6A completed a science experiment. We attempted to mix water and oil together in some glass jars. We used blue food dye to ensure we could easily determine the difference between the water and oil.
We found that the water and oil do not mix together. The oil came to the top and formed a layer above the water.
After completing some research, the students discovered the water and oil do not mix because they are made up by different molecules that cannot mix with each other, which forces the oil to sit on top of the water.
