They grow up to two feet in height per year until they reach 200 to 300 feet high—then, like people, they grow outward in girth.• The average base of a sequoia can be as much as 40 feet in diameter—and a few reach more than 100 feet in diameter.

The layers appear as a set of concentric circles known as tree rings. Each layer consists of two colors of wood: light-colored "earlywood" that grows in the spring and summer plus darker, denser "latewood" from the fall and winter.

In this activity, students are introduced to tree rings by examining a cross section of a tree, also known as a 'tree cookie.' They discover how tree age can be determined by studying the rings and how ring thickness can be used to deduce times of optimal growing conditions.

• The thick, spongy bark can be as much as 31 inches thick.

• Its branches can be up to eight feet in diameter (many of these branches being thicker and longer than an average tree) and can have more than 11,000 cones, ideally dispersing more than 300,000 seeds per year.

Next, they investigate simulated tree rings applying the scientific method to explore how climatic conditions varied over time.

The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness.

This past summer, my family and I took the opportunity to walk among the giant sequoias in King’s Canyon National Park in California.

While pondering these phenomenal trees, which are a truly magnificent part of God’s creation, I thought of a number of spiritual lessons.

A cross section from a tree therefore shows an irregular sequence of wide and narrow rings.
