We learned more about chemical reactions by polishing pennies. We dunked our grimmy pennies in milk, water, apple juice, soda, and lemon juice. The Good Housekeeping Seal of Approval goes to...lemon juice. The acid in the juice helps to break down some of the copper oxide on the penny.
We also did some math vocabulary review. Too bad these kiddies haven't seen $25,000 Pyramid!
The denominator is acting like he is not LOVING this!
And we had to say goodbye to our dear friend and classmate JamarriA! We will miss you!
