Thinking through the Clock of Eras Next Step

As I began thinking about the Clock of Eras in preparation for the Timeline of Life work, I began to wonder about a transition.  There seems to be so much that is skipped in this work.  I understand the impressionistic nature of the work yet, especially for the slightly older child, there are swaths of information that can inform deeper lessons like organic chemistry. So, I broke out the Claremont lessons for inspiration.  I’ve always admired the attention to the beginnings of time and the excitement that they bring the children.

As it is a new year, I thought that perhaps we should look back at the beginnings.  I began to create a series of hybrid lessons.

Detailed Discussion of the Earth’s Development Six Parts

Primary Aim:  To take the impressionistic lesson from the lower elementary presentation and revisit and expand upon it in the later upper elementary or erd kinder.

Secondary Aim: To continue the awe of the gifts that God gives to all the creatures He creates.  Moving the awe from all the work that had to be done before mammals could survive to a detailed look at the complexity of the work that was done.  Here is the beginning of the process.

Materials to make or acquire for All Parts of the Lesson: A 25 foot length of color coordinated fabric representing 15,000,000.

The fabric is divided into eons and eras.

Pre-hadean and Hadean 66.66 inches  (grey)

Archaean 33 inches  (black)

Proterozoic 162 inches (yellow)

Paleozoic 23.08 inches (blue)

Mesozoic 10.75 inches (brown)

Cenozoic 4.25 inches (green)
