Charred Marshmallow Souffle
A new event called "The Mole"was unveiled at BCCE 2018. I told the story of how one of my students discovered how to make marshmallows spark in the microwave oven.

Based upon reader comments on previously published, Chemical Mystery #12, I experimented and found that this demonstration is easy to pull off with relatively inexpensive and easy to find materials.

"The Learning Pit" metaphor constructed by James Nottingham can serve as an important part of establishing a culture for learning in the high school science classroom.
In this post, I share my thoughts about positive relationships as well as some of the activities that I do on the first day of school to make connections with my students.
Are you up for trying an ambitious experiment that combines archeology, instrumental analysis, and a search for patterns in data? Then this activity might fit the bill!
A favorite demonstration is to boil water by lowering the pressure in a bell jar using a vacuum pump. Unfortunately, purchasing a bell jar, vacuum plate, and vacuum pump can run upwards of $1,000 which poses a hardship for many teachers. Here are two simple and inexpensive demonstrations of phase equilibrium and vapor pressure.
