This has certainly proved to be a rainy winter! Here is an activity I had come across several times and always thought it looked a little silly and passed it up. On the recommendation of a friend I finally gave it a go, and boy was I glad I did! Thomas LOVED it and insisted that he help Daddy clean his pennies when he got home. I loved it because it involved materials I already had and some great learning opportunities!
Materials:
- baking soda
- vinegar
- pennies
- eye dropper (or medicine dropper)
- measuring spoon
- small bowl
- large bowl of water
- towel
First, I showed Thomas what a penny was and had him go through our coin jar and find all the pennies he could and pull them out.
Next, he put one penny in the small bowl, measured out 1/4 teaspoon of baking soda, and dumped the soda on top of the penny.
Then he filled a dropper full of vingear and carefully counted out drops on top. Of course it then it erupted in bubbles which got Thomas VERY excited.
After all the bubbles died down he transferred the penny to the larger bowl of water to "rinse" the penny off and then on a kitchen towel to dry. Then it was time to do another one!
He was happily occupied for about 45 minutes! The whole time he was learning: what a penny is, visual discrimination, remembering and following steps, counting, and observing chemical reactions. All in all a great activity!
