Maddie was our scientist a few weeks ago and she did the experiment Penny Polish.
It was pretty amazing!
Here she is getting set up and ready to go...
She had three solutions to try to clean the pennies with: soap and water, lemon juice, and salt and vinegar. Each child predicted what they thought would work the best, most chose soap and water.
Maddie carefully stirred them around in the bowls and then showed the class how clean it was.
At the end, it was obvious which one worked the best. The salt and vinegar made the penny so shiny. It was amazing!
Maddie did such a great job with her experiment. Thank you!
