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.

You Said It! Thermal Energy Product Reviews


You Said It! Product Reviews - Educational Innovations NewsletterTo put it simply, we think thermal energy is cool!  Many of our best-selling discrepant event demos are related to thermal energy, as you’ll see from the reviews below.  With our Ice Melting Blocks, you can ask your students to predict which block will melt an ice cube more rapidly…  Use a Chemical Heat Pack to challenge your class to figure out how heat—usually associated with melting—can be produced by a reaction that turns a liquid into a solid…  Or dazzle them with Nitinol Memory Wire that changes shape upon heating!

Demystifying the Poly Density Bottle


Dr. Kenneth Lyle, Duke University Department of Chemistryby Dr. Kenneth Lyle

The demonstration

The Poly Density Bottle is a fascinating demonstration primarily due to the phenomena being counterintuitive to what one would expect.  The bottle containing white and blue beads suspended in a clear and colorless liquid is shaken vigorously, distributing the beads randomly throughout (bottle A).  Upon standing, the beads separate from one another (bottle B) with the white rising to the surface while the blue sink to the bottom (bottle C).  Then, the two sets of beads move towards one another (bottle D) meeting near the middle (bottle E).  This demonstration can be easily repeated again and again.  And, once prepared, it can be stored for subsequent use year after year.  No additional preparation is required.

The “Magic” of the Soother Ooze Tube


KenByrneBy Ken Byrne

Someone once told me that all magic is science, and all science is magic.  To me, a magic show is a series of puzzles for me to solve, trying to figure out just how they pulled off an illusion.  My favorite science demonstrations are much the same.  I love those demonstrations that make me scratch my head and ask, “Why?”

Here is one of my favorites that is easy and inexpensive.  It feels like a magic trick, but it is all science.  It simply involves rolling a cylinder down an inclined plane.  Sometimes the cylinder will roll down quickly.  Other times it will crawl down slowly. Read the rest of this entry »
