Bilateral Diagrams

With the applet below you drag counters to one of the eligible positions on the bilateral diagram. After you get the desired configuration, press the Interpret button to check your understanding.

On the left from the applet there is an original Lewis Carroll's verse that helps remember the purpose of each color.

COLOURS FOR COUNTERS See, the Sun is overhead, Shining on us, FULL and RED! Now the Sun is gone away, And the EMPTY sky is GRAY!
