Have students label with sticky notes the different liquids.
Drop small objects into the liquids and see if the stay in place or sink.
After the students explore on their own, you can give them more specific directions:
1. Start your column by pouring the honey into the cylinder. Now, you will pour each
liquid SLOWLY into the container, one at a time. It is very important to pour the
liquids slowly and into the center of the cylinder. Make sure that the liquids do not
touch the sides of the cylinder while you are pouring. It’s okay if the liquids mix a
little as you are pouring. The layers will always even themselves out because of
the varying densities. Make sure you pour the liquids in the following order:
. Honey
. Karo syrup
. Dish soap
. Water
. Vegetable oil
. Rubbing alcohol
. Lamp oil
.As you pour, the liquids will layer on top of one another. After you pour in the
liquids you will have a seven-layer science experiment
Science Behind it
The same amount of two different liquids will have different weights because theyhave different masses. The liquids that weigh more (have a higher density) will
sink below the liquids that weigh less (have a lower density).
