Good work!  Lighting the fire of enthusiasm is one of the most important things we can do.



I have several boxes for my Mr. Science presentations that occur about once a year, with my plan for increased activity in a few years, as I approach my retirement.  The boxes include neat stuff like:

Electricity and magnetism with:

      1. Killer magnets that many adults can't separate.

      2. A cut-apart magnetron to show that there's really nothing in a microwave oven.

      3. A head-positioning linear motor from a hard drive, driven by an audio signal, touched to a toothpick in your mouth, giving music into your head via bone conduction.

Optics with:

      1. Lasers (multi-colored, including UV) and diffraction gratings.

      2. UV flashlights (with yellow high-lighter to mark on your skin (invisible without the UV),

      3. Polarized filters (showing multicolored kaleidoscope effect with random layers of scotch tape)

      4. A 12-inch diameter Fresnel convex lens to put in front of your face (or to pop ants in the sun).

Thermal with:

1.      Various rods (steel, copper, and heat pipes) to hold and dip one end into hot water.

2.      Peltier effect device in a box with a hot/cold polarity switch.

3.      Thermal liquid crystal sheets that change color and show thermal handprints on a table.

4.      FLIR thermal imaging camera (borrowed from work).

Physical stuff:

1.      Vortex cannon.

2.      Sonic lens (heavy gas in a balloon).

3.      2-liter water bottle rocket launcher.

4.      Magnesium fire (only shown to limited subset).

And a bunch of other stuff.



I have fun every time I demonstrate the stuff, usually letting the demos be guided by the questions and enthusiasm of the group.



Please let me know if you have favorite things you like to show to amaze kids of all ages.



Thanks

Carl

Thanks for sharing that gem with us. Kids can be absolutely amazing, the purity of heart and the thirst for knowledge. It takes guys like you (s) to light the fire that smolders inside them! Thank you for a job well done many times over!

Subject: [TN] Periodic Table



Good morning all,

In light of Dave's Friday Element Quiz, this is something that I absolutely have to share.



Dave and I are priviledged to do science and engineering demonstrations at Iowa (sometimes farther) schools, which we call the Rockwell Road Show.

Dave is one of the originators of the program over 25 years ago. I have been doing it for about 16 years now.  We both have a blast doing this (and that is an understatement).  It is not unusual, when we have done the show for Middle Schools or Elementary Schools, to have the kids write thank you notes and indicate what they liked best about the show.  It is very gratifying reading them.  But a few weeks ago, Dave and I did a show for the Anamosa (Iowa) Middle School.  It was a fantastic show and the kids REALLY got into it.  This morning, their science teacher dropped off the thank you notes and a large rolled up piece of paper.  When we rolled it out, we were absolutely blown away.  I asked Steve Gregory to post it on his site.

A Periodic Table of the Elements, with a thank you note on the back of each element.  Stunning.



Maybe next year, I can get them to do the half fractionals.
