Layering of Oils
The fourth lesson, taught by Ms. Alicia, was about the layering of oils. In it, we looked at the weights and density of honey, corn syrup, maple syrup, dish soap, water, and vegetable oil. We then put them in a jar to see if they would mix together. We observed that they instead stayed separated into their layers based on their densities. The honey, which is the most dense (most mass per volume-heaviest for the same amount of liquid), sunk to the bottom and stayed there. The vegetable oil was the least dense and floated on the top of the rest of the liquids. Each child was able to pour a liquid into the large jar and discuss what happened.
In this activity, we made a chart and wrote down what the children were saying about what they thought was going to happen, what was currently happening, and what had happened. The children had great predictions, saying things like "they're going to mix together and make purple" or "it's going to explode." One child said that one liquid was heavier and would stay under another.
The students enjoyed this activity and learned about how liquids that are lighter layer on top of liquids that are heavier.
