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.
A simple, but tricky experiment is displayed. Can you figure out how the trick was done?
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...
I added an extra step including a follow up Claim, Evidence & Reasoning activity to the familiar whoosh bottle activity.
Light is a challenging topic in chemistry. In this article, I share an outline of how I approach the content related to interactions between matter and light using activities, a simulation, demonstrations and whiteboards.
Tom Kuntzleman presented a story titled "Charred Marshmallow Souffle" during The Mole Storytelling Jam held as part of BCCE 2018. Listen to his podcast.
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.
