Kingdoms and animal groups

The cards are drawings of real organisms. The close-ups show what a hand lens shows; cells need a microscope, so they come as prints: micrographs or labelled diagrams. The virus is drawn as a diagram: real viruses are far too small to see even with a light microscope.

A card goes into a tray only when the group you choose fits its features. Your first guesses are kept in the table, so you can see which ones changed when you looked closer.
