Chromatography atmosphere

This resource is part of the Polar Explorer Resource Collection

Surrounding the Earth, like a blanket, is the atmosphere. Without it we couldn’t survive. The atmosphere is a layer of gases, the air, which plants and animals use to respire. It is made up of 78% nitrogen and 21% oxygen, as well as many other gases in much smaller quantities.

This unit gives children a basic knowledge of the Earth’s atmosphere and the ozone layer. The children will use chromatography to model the atmosphere surrounding the Earth.

I've tried this and, even after waiting over an hour, it doesn't seem to work. I used a Sharpie black felt tip. Does anyone know if you need a particular type of felt tip for this to work and how long it typically takes to separate?

We would only typically recommend that permanent marker pens are avoided but would expect this to work with a variety of black felt tip pens in most cases.
