As infants we learn to stack blocks, taking one block and placing it on top of the other, hoping that it will not topple. Just as we learned to build a tower of blocks we can learn to build a stack of liquids. Most liquids, when poured into the same container will mix. However, some liquids do not mix with others so instead they separate into layers. What happens if you drop a small amount of oil into a glass of water? The oil floats to the top. In this experiment we will create a liquid gradient based on density.
In this experiment students will learn about density by creating a liquid gradient.
