Density Lab (Class Response)

Last week, I was assigned to a group. We where supposed to do a lab based on how liquids don't mix together if they don't have the same density. For example, we put ketchup and poured, with caution, syrup on it, the syrup wouldn't mix with the ketchup. One thing I learned is that when you put some thing less dense first, then pour something more dense than the first liquid, the less dense liquid will make way for the more dense liquid and the less dense liquid will rise to the top. Also, when my group and I left the cup that had the liquids over night, they rearranged. The liquids rearranged themselves from most dense to least dense. Lastly, that if you piur the liquids carelessly, then the liquids will mix and will not rearrange to be in order.

-A liquid's density can change due to the temperature
-The density of water can change. Depending on it's temperature.

My opinion about this fascinating lab is that it taught me many things I have never new before. For example, I never knew that liquids with different densities made boundaries and never got mixed when the where pour carefully. All in all, I think that this was a great lab and it taught me many fascinating facts.
