Edible Aquifers

Yesterday, we learned all about aquifers. We talked about the different layers of the ground, and how groundwater is stored. We used gummy bears, chocolate chips, and crushed cookies to represent the sand and gravel found deep in the earth. We then "made it rain" using Sprite (which represented our groundwater.) We "protected" our groundwater with a confining layer (ice cream) then added more gravel and sand and soil (sprinkles).

Next, we put a few drops of food coloring into our aquifer. This represents pollution. At first it didn't do much but set on top of the confining layer. However, once we "dug a well" (put a straw into our aquifer), and started "pumping the well" we noticed the pollution started seeping down into our groundwater! YUCK! The it "rained" again, and the pollution spread EVERYWHERE!

So what did we learn??? To protect our Earth, of course! It is so easy to pollute our drinking water, so we need to be extra careful.

After the pollution!
