You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
The “bucket launch” is a fantastic experiment you can do if you have access to liquid nitrogen. Depending upon conditions, we have observed the bucket to launch anywhere from 80 to 160 feet high. See the video.
I am fascinated by the chemistry of pennies. I have tried several experiments found in the Journal of Chemical Education.
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
When ignited by a glycerin/permanganate reaction, an aluminum/iron oxide mixture reacts vigorously and spectacularly, producing molten iron and aluminum oxide.
Powdered aluminum and powdered iodine are mixed together. Adding drops of water to the mixture initiates a reaction.
Powdered manganese and powdered iodine are mixed together. Adding drops of water to the mixture initiates a reaction.
