As part of our Integrated Studies topic of Under the Sea, the Prep boys have been looking at floating and sinking, culminating in the creation of an ocean in a bottle. The boys had to do a lot of investigating to determine what they could use as the clear liquid at the top. Suggestions ranged from plain water to dishwashing liquid. Our final product was Baby Oil, which was perfect! The next task was to find something which would float on water but sink in oil. The boys were very surprised that wooden objects floated in the oil. Our boats ended up being made from milk carton plastic, and they do actually look like they are floating on the water! We also made some very cute little clay sea creatures to live on the bottom of our bottle.
