Product Description
Awesome hands-on science experiment that explores chemical change using very easy-to-find household materials. Students will try to clean pennies by dipping them in various liquids and find out which ones work best at polishing them up. Students will also discover if the liquids they are using are acids or bases, and what effect it has on cleaning the pennies.

"Polishing Pennies" includes ready-to-go lab sheets and data tables to print out for the class. There are also slides describing chemical change, intro to acid and base, an explanation to the science behind the experiment, and a extensions page that allows the class to take this experiment even further.

This activity can get messy, which makes it that much more fun. Also, most materials should be easy to find except for the litmus paper. Luckily litmus paper is cheap and can be found online. Here is a link to 100 strips of litmus paper for only 2 bucks
