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.

Students broke up into teams with the question, "Do bowling balls sink or float in water?".
For this coming school year, I would like to kick off every unit with a discrepant event, and then bring it back at the end of the unit for students to explain with their new model.
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.
A variety of activities performed at a science camp that relate to the chemistry of the solar system are reported. These activities could prove useful in the chemistry curriculum or in planning for National Chemistry Week in 2018, the theme of which is Chemistry is Out of This World!
I have been interested in the adsorption properties of shells and other common materials. I decided to test the adsorption properties of almond shells towards methylene blue and I am sharing how it went here.
How do you demonstrate how a buffer system works? I did some brainstorming, devised a plan and it went well. This post is a description of what I did.
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
