What You Want to Know
Can liquids float on top of each other? Which liquid is lightest? Which one is heaviest?
What You Think Will Happen
Beside each arrow, write water, corn syrup, alcohol or cooking oil to show how you think
the liquids will settle in the cup.
What Happened
Illustrate (draw) your observations. Write water, corn syrup, alcohol or cooking oil to show
how you think the liquids will settle in the cup. Also be sure to show where four “sinkies”
and “floaties” rested in the stacked liquids.
What it Means
Density is a measure of how much matter there is within a given space. A denser liquid
will sink in a less-dense one. What do you observations tell you about the densities of
water, corn syrup, alcohol and cooking oil?
