Clock of Eras

Traditional version from Azoka Company

Looking at “cosmic hours,” children have another way to grasp the concept of the relative amounts of time it took for Earth to form and for different types of life to develop.

Comes with a colored control (15" x 20") on poster board, pre-cut arrows and key, and set of loose chart pieces for building the clock. Color-coded to match the Timeline of Life (EM824, EM825).

Please note: We also have this item available in the ICS Version (EM105) from the International Commission on Stratigraphy. Updated in 2014.
