A 2011 article from the National Oceanic and Atmospheric Administration linked recent severe droughts in the Mediterranean to anthropogenic climate change. Now Francesco Femia and Caitlin Werrell assert that the drought (and agricultural mismanagement) lead to the displacement of a million and a half people in Syria, which helped spark the current civil war.
WikiLeaks, Drought and Syria by Thomas Friedman: Cables from 2008, outline Syria’s growing recognition of the potential for civil unrest because of the drought.
The Shiloh National Battlefield is only a couple hours east of Memphis (or west of Nashville), and its proximity to Corinth, MS, and a state park with a hydroelectric dam, make it an excellent place for an immersion trip during the cycle when we study the U.S. Civil War and electromagnetism. Two years ago, on a couple beautiful, sunny days in the middle of spring (early April), almost on the anniversary of the battle, we made the trip.
Paleozoic (?) (250-550 million years ago) fossils from Pickwick Landing State Park.
We drove over on a Tuesday morning, and since our very nice cabins at Pickwick Landing State Park were not quite ready yet, we ate the lunch we’d brought with us at a picnic shelter on the park grounds. The choice of picnic shelter number 6 was serendipitous, because not only was it beautifully located, but just down the hill, at the edge of the water, is an excellent outcrop of fossiliferous limestone.
The next morning we hiked along the Confederate line of advance during the Battle of Shiloh.
Reenacting the Confederate skirmish line at Shiloh.Confederate or Union?
It was a relatively long hike, but useful in that it allowed students a feel at least for the scale of the battle, and the conditions the soldiers endured. There was also a nice museum at the end, with an interesting video and an excellent demonstration from one of the park rangers (you need to book an appointment ahead of time).
Finally, on Thursday morning, on our way back to Memphis, we stopped at the Civil War Interpretive Center in Corinth, Mississippi. The museum is excellent, especially the Stream of American History, which is abstract enough that it makes a great puzzle for students to figure out.

Stalactites dripping down into a subterranean pool at Meramec Caverns.
On the last day of our trip we drove an hour west of St. Louis to Meramec Caverns. If you’re ever on I44 heading out of St. Louis you can’t miss it. From 30 km away you start seeing billboards, sometimes in pairs, almost every 100 meters.
Largely this is because it is a privately owned cave. Privately owned also means that they can do things to “enhance” the cave that you would not see at a National Park like Mammoth Cave. The light shows in certain caves were particularly interesting. Our tour guide was pretty good, entertaining and scientifically accurate for a general audience.
Colors created by different metal anion precipitates.
The presence of different colors in the rock formations (red, white and black) due to different metals in the carbonate precipitates could tie in very well with our discussion earlier this year of ionic bonding.
There are also historical tie-ins. The cave was the site of a skirmish during the civil war, because the bat guano was being used to produce gunpowder. Jesse James participated in that engagement and later used the cave as a hideout.

Finally, they have a reconstructed hut, which although it has nothing to do with the cave, has a bootlegger’s still does link with our discussion of steam distillation.
Salvage of the ironclad, USS Cairo, in Vicksburg National Military Park.
Four hours away, Vicksburg, MS. is just within reach for an immersion trip so, since we were in the area, I scoped it out for a future trip. Vicksburg was the final town to fall before the Union could control the Mississippi River and split the Confederacy into two, so it’s historically important. The Vicksburg National Military Park is chock full of monuments and markers that give a good idea about the chaos and carnage of the battle for the town, and even a chance to observe practical application of simple machines and steam engines.
Rifling in a cannon.
The park could complement Shiloh and Corinth quite nicely since Vicksburg’s importance was because of its control of transportation routes, just like with Corinth. It also has the salvage of the USS Cairo, an ironclad sunk during the Civil War. Much of he Hull is still missing so it’s a wonderful chance to see all the mechanisms and engines in a steam powered ship.
Watermill at Grand Gulf Military State Park.
What I found most interesting, however, were the old watermill and farming equipment at Grand Gulf Military Park, about 45 minutes south of Vicksburg. They seem almost in working order, and if you’ve been discussing simple machines, as we have, it’s a great opportunity to see how they were applied in real-life.

The watermill is quite picturesque, making it a great subject for sketching or drawing. I like to combine art and science in this way when possible. Grand Gulf also has a small, submarine used by bootleggers during prohibition which is quite the curious piece of engineering.
