(Time scale:
Each black or blue block on the upper blue panel represents 10 million years. The time
scale stretches around the room for 4.5 billion years.)
This blue arrow leads to a panel marked
with black numbers in yellow ovals. Each number indicates the time period when a group of
animals, or plants, or a geological feature originated. Numbers in yellow ovals correspond
to numbers on the right side of this quizboard.
To match items in column B with their
time of origin in column A, press and hold down a button from each column at the same
time. If you have correctly matched the item with its time of origin the light below will
flash on.
