Tom Kuntzleman conducts a safer "mercury-like" beating heart experiment with an added splash of gratefulness.
Can you use your knowledge of chemistry to figure out what is going on in Chemical Mystery #19?
This blog post includes short descriptions of demonstrations and props that Dean Campbell has used while teaching his collegiate General Chemistry I course.
Beautiful, metallic mirrors of copper or silver can easily be formed in test tubes. Simply add the appropriate metal salt to a test tube, and heat! These reactions should be performed in a fume hood.

The solution to Chemical Mystery #13: Bye Bye Blue! is presented. This experiment is useful to demonstrate to students when discussing acid-base indicators, neutralization reactions, or the acidity of carbon dioxide when it dissolves in water.
This blog post may be a bit non-traditional, but in this submission I recall a memory from early in my teaching career when my dad (who was an environmental chemist) visited my classroom. The day remains embedded in my memory bank, and had a profound impact on how I view labs - as an opportunity to extend the learning.
Inspired by Tom Kuntzleman*, I started using mysteries in my chemistry curriculum this past year. The first mystery I shared with my students was burning water. While my magician skills aren't perfect, I was able to get the students asking questions and proposing hypotheses. For my IB students, it really allowed me to delve into a number of topics (e.g. combustion, intermolecular forces, polarity, density). And thus an idea was born: Using one mystery per topic. In this blog post I'll discuss my beginning effort to find or develop a mystery for each topic within the IB Chemistry curriculum.
