Earlier in the week we discussed the Statue of Liberty. Where it's located, what it looks like, why it was built, etc. To further our interest in this symbol of freedom and democracy, we pondered on why the statue of liberty is green. The kiddos thought maybe it was just old or that people were making it dirty with trash.
I then passed a penny around the table and asked the kiddos what it looked like. Before I even mentioned the Statue of Liberty being related to the penny, they noticed that the penny I passed around was a tint of green! "The Statue of Liberty is made of a penny Ms. Kylie!" Oh the comments that make my day!! We talked about the penny I passed around being very old (made prior to 1980) and that it was exposed to oxygen in the air for a very long time. Once copper is exposed to the oxygen in the air for an extended period of time, it turns to a hint of green (or described as dull).
Before conducting our experiment, we colored in three pennies on "Our Penny Experiment" worksheet. We then mixed the salt/vinegar solution. Placed the penny in the solution for 10 seconds. The kiddos were AMAZED at what they saw. "Ohhhhh WOW" "It's so clean Ms. Kylie." "We should do this to the Statue of Liberty!" #I LOVE MY JOB! We then completed "Our Penny Experiment" worksheet by coloring the pennies after our solution and answering the question! We all had a great time with this penny experiment. :)
