#PPOD: Due to airglow, which is usually hard to see, the sky can glow like a giant rainbow. Disturbances like storms cause gravity waves, making airglow visible. The colors likely originate from various molecules: deep red from OH molecules at 87 km high, and orange and green from sodium and oxygen atoms higher up.

I spent an hour yesterday working with one student. She was scared of the soldering iron. "Do your parents let you use the stove at home? It could burn you too, right? But we understand how to be safe and it's not a problem."

She did a beautiful job on her project and learned the names of many parts and learned that she can be scared to do something but still be extremely successful.

This is only really possible because my classes are small. If I need to work with a student I can do it.
