Some orange peels can cause balloons to pop. The compound in orange peels called limonene is responsible for this effect. Limonene is responsible for the wonderful smell of oranges, and it is a liquid at room temperature.
In this age of scientific inquiry, molecular modeling, digital classrooms, and differentiation, I felt downright guilty about any teacher-centered time. My classroom is flipped after all. I’m not supposed to be lecturing, right?

Historically, my students report significant figures as one of the most confusing concepts in honors chemistry. My recent blog post described the process of transforming my introduction into an inquiry activity. I’ve also re-worked my practice activities to be more directed to specific student needs, more focused on spending time with small groups, and more dedicated to active learning. This four step tiered plan works for me.
Hello and welcome to my new blog. I am Michael Morgan and I teach AP Chemistry, Honors Chemistry, Chemistry, and pretty much all things NErDy at Francisco Bravo Medical Magnet High School in Los Angeles, CA. I have been teaching for almost 30 years. In Los Angeles I am a rare bird, a chemistry teacher that actually studied chemistry in college.
Education “buzz words” can be meaningless jargon, or they can challenge us to consider new approaches to teaching and learning. Don’t let the jargon be a buzz kill!
“Significant figures are so confusing,” says my former student, who is currently taking AP Chemistry. My PowerPoint lecture with lab to follow didn’t work. Convicted, I wrestled with transforming my tired lesson. I embraced the buzz words. Let’s look at a significant figures lesson that changed my compliant, quiet learners to ENGAGED COLLABORATORS.
Conducting experiments with liquid nitrogen experiments is a sure-fire way to energize many chemistry lessons. Check out the Misbehaving Balloon demo!
The Rural Trust's Global Teacher Fellowship program will be awarding up to 25 in 2015 to support the professional and personal development of rural teachers.
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.
