When should you use the Physical and Chemical Change poster?

Ask whether a new substance appeared. That is the whole test. A wall chart earns its place by being glanceable from where the work is happening, so Physical and Chemical Change belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.

What other posters go with Physical and Chemical Change?
