Chemical Connections to Climate Change

It is becoming increasingly important for citizens to understand various concepts related to climate change and global warming. This post describes several chemical concepts that are pertinent to these issues, in the hopes that teachers of science and chemistry can introduce the topic of climate change into their classrooms and everyday discussions.

The Dry-Ice-in-Water Cloud

Have you ever wondered where the cloud comes from when dry ice is placed in water? If you think the answer is “atmospheric water vapor”, be sure to read this post because experimental evidence suggests that this explanation is wrong.

Veritasium in the Modeling Classroom

Modeling InstructionTM is specifically designed so students construct meaning without being told what to think and I needed videos that aligned with this philosophy.  That’s when I ran across this TedEd talk with Dr. Derek Muller.

The Gas Laws Are Out of This World!

A few years ago, we launched a weather balloon during our summer science camp. The balloon reached an altitude of 30 km (100,000 ft)! Among other things, this project ended up being a great way to teach campers about the gas laws and how atmospheric pressure decreases with altitude.
