Montessori Penny Polishing Activity/ Dollar Bill Lesson

Montessori Practical Life and Science Experiment
Penny Polishing

President’s Day is a great time to introduce the Presidents to young children in a way that is sparks their curiosity. This hands-on experiment is wonderful for their development of a child’s fine motor skills. The photo shows the Montessori inspired experiment pennies, lemon juice, dropper, 1/8 teaspoon measuring spoon, salt and a cloth for polishing.

You can present this to the child by placing one penny in an empty flat dish and then spoon 1/8 teaspoon of salt onto the surface of the penny. Then squeeze 2 drops of lemon juice on top of the salt. The acidity of the lemon juice combined with the abrasiveness of the salt will naturally clean the penny’s surface. Then, using the cloth, show the child how to wipe off the polish.

This is a great Montessori practical life and science experiment. Have a good supply of pennies because young children will enjoy repeating this activity over and over again.

For the “Dollar Bill Activity,” you just need a tray containing a dollar bill and a magnifying glass. Have a small bowl with a penny, nickel, dime, quarter, and half dollar. Your child can study
the money with a magnifying glass and you can discuss which President's are on the currency.
