Geology

Maybe it was the growling of my stomach as I began writing this post. Maybe it was watching the 3 reams of paper go through the copy machine: worksheets destined for student desks, and ultimately, the trash. Either way, when I started researching creative methods for teaching students about continents, I looked for engaging and meaningful activities that would leave students with a lasting curiosity about how the earth came to look the way it looks today. Many students have learned about this topic on a very basic level, so I was looking for resources that would challenge students of all ages and skill levels to make learning connections with other subjects.

Sometimes the simplest things make the most memorable lessons. You can find rocks just about anywhere, and most kids have collected them at one time or another. Careful examination, comparison, and classification are a big part of rock collecting. Kids who enjoy finding and sorting rocks will learn a lot about geology and earth science while doing something they enjoy.

When my older sister was in elementary school, each student was given a starter rock collection. The rocks were stored in plastic boxes, where each little compartment housed a rock specimen nestled in some cotton batting. I most liked the samples that contained quartz, which caught the light and sparkled. Unfortunately, by the time I started elementary school, the starter rock collection program had been discontinued. Bummer!

The recent earthquake in Japan has vividly illustrated just how powerful natural disasters can be. Most of the horrific, widespread damage was caused not by the earthquake itself, but by the resulting tsunami. After the earthquake, residents living on the northeastern coast of Japan had only minutes to seek high ground before the waves came crashing in. Many never made it.

This week we have a guest columnist, Terry Smithson the Director of Marketing for JES & Co., covering the topic of earthquakes. Peggy will be back in a few weeks.

On October 17, 1989 at 5:04 P.M., I was in the upper deck at Candlestick Park in San Francisco for game 5 of the World Series. I had a childhood friend that was visiting from North Carolina and had never seen a professional baseball game. Needless to say, he did not see this one either. The game was postponed due to a 7.1 magnitude earthquake centered on the San Andreas Fault in the Santa Cruz Mountains near Loma Prieta Peak which is about 50 miles south of San Francisco. This quake only lasted between 10-15 seconds. To put it in perspective, the recent quake in Japan lasted for just over 2 minutes.

Earthquakes are mysterious things. We understand why earthquakes happen, but still lack the ability to predict the magnitude of a quake or when such an event might occur. Once an earthquake begins, current technology can only provide a few seconds’ warning before severe shaking arrives at a specific location. For most people, the first sign of an impending earthquake occurs only once it’s begun.
