Today we performed an experiment. We placed 4 pennies in water and 4 pennies in salt water. Then we rinsed two pennies from each cup. We placed the pennies on a place mat and we are letting them dry over night. What are some of your predictions? What will the pennies look like in the morning.

I think the salt water pennies will look white from the salt.
