  1. Sometimes, what you think will happen, doesn’t happen. Good use of different solutions. I like your ideas if you try this one again.

  2. What an interesting investigation of so many different things that might be used to clean pennies. I am curious how many pennies you tried to clean in each substance. I wonder what else you might use to try to clean the pennies. I hope you keep exploring how things work best using science!
