Melting Pennies

I am fascinated by the chemistry of pennies. I have tried several experiments found in the Journal of Chemical Education.

To Inquiry or not to Inquiry . . .

Here is something to ponder as you think about your lab experiences this year:  I have been using an excellent inquiry lab for the past few years.  I think it does a fabulous job guiding the students through the amazing (yet often dull to students) world of specific heat equations and learning about calorimetry.  However, this semester, I returned to the old, traditional calorimetry lab.  I wan

Thermite reaction

When ignited by a glycerin/permanganate reaction, an aluminum/iron oxide mixture reacts vigorously and spectacularly, producing molten iron and aluminum oxide.
