Engaging Students with Electrochemistry… and Goldenrod Paper


Educational Innovations Blogby Nancy Foote

I’m in love with goldenrod paper.  I’ve loved it for a long time.  In my never-ending quest to emotionally entangle my students in the content of our science curriculum, Color-Changing Goldenrod Paper provides a long-lasting entanglement.

If you’ve never done the bloody handprint goldenrod paper demo with your students, you are truly missing out—and so are they)!  This is the most engaging “engage” part of the 5 E’s I’ve ever experienced.  I like to do the bloody handprint demo around Halloween, but we don’t do acid/base chemistry until February.  That’s a long time to wonder, ponder and try to figure out exactly what is happening.  But that’s for another blog post.

That is exactly what happened to me a few years ago.

The Chemistry of Currency

The wonders of magnetic ink!

INTRODUCTION

Demonstrating the magnetic ink used in printing US currency has proven to engage audiences of all ages because of its relevance to everyday life.  Nearly everyone has used machines that distribute and/or accept currency but few understand how the machines distinguish between the various denominations.  The key is in the face of each denomination.  Magnetic ink is used in the printing of the currency.  Each denomination has a different face and, therefore, a different magnetic signature.  Similar to a bar code reader, the machines recognize the denomination by its magnetic signature.  A strong magnet, such as a neodymium magnet, can be used to demonstrate the magnetic character of US currency.
