The oxidation of reducing sugars by silver ions to form a silver mirror is a classic chemistry experiment. In this experiment, sugars that contain aldehyde functional groups are reacted with an ammonia-silver complex to form silver metal, which forms a shiny metallic mirror:
chemical tests on coins

I recently shared some simple experiments using magnets and coins that connect to the 2019 National Chemistry Week (NCW) theme, “Marvelous Metals!”1 Because coins are familiar items, made of metal, and so very easy to obtain, I think doing experiments with coins is a great idea for NCW 2019!
Bouncing batteries

Did you know there is a simple test you can do to see if an alkaline battery is fresh or dead?1,2 All you need to do is bounce the bottom of a battery onto a hard, flat surface. If the battery is fresh it won’t bounce very well. If the battery is dead, it will bounce very high. Check it out in the video.3

A voice piped up, “What if you tried it with a bigger marble?” I was thrilled to hear the third grader’s suggestion. It was a great extension to consider in the group experiment we were doing, but it was bigger than that.
Starting materials for demonstration

I found a version of this demonstration online a couple of years ago. I admit, when I first tried it with my class it was mostly for a crowd pleaser to demonstrate the activity series of metals, but I then became very intrigued by the processes occurring.

Looking for an easy, hands-on experiment to use in your classroom at the beginning of the school year? In the June, 2013 issue of the Journal of Chemical Education, Isao Ikemoto and Kouichi Saitou describe a simple experiment to demonstrate the electrolytic dissolution of copper ions from a copper electrode.

I was lucky enough to be part of the second cohort of Target Inquiry teachers at Grand Valley State University. As part of the program, we each wrote, tested and revised two chemistry laboratories for use at the high school level. One of mine is the lab I am sharing here.
