Taking on Woo in Martial Arts, 1 1/2 hour Science Credit

TAM: James Randi Foundation: Skepticism: Science: Video: 1 1/2 hour Science Credit.


When a student exists their formal education, sometimes it seems as if education has stopped and working must begin. However, people can retain and support a life long love of learning without having to attend formal education. For example, a group of people calling themselves Skeptics go to The Amaz!ng Meeting annually and hold various talks about an assorted collection of  topics unified by the idea of Skeptical thinking. 

This particular topic, Martial Arts, may well appeal to boys with an interest in martial arts and even more so for a child who reads comic books or watches various superhero movies. As a young boy, Superheroes had my admiration. 

In the case of my daughter, being a particularly concerned father, I have sought to awaken and interest in martial arts within my daughter. My rational being: "Boys have an off button. If you hit it hard enough, often enough, they will get off you." My daughter has taken some classes in Kenpo with Jeff O'Donnell. As such, she might have a more than passing interest in the topic of martial arts and I can see some value in setting reasonable expectation of martial arts in her mind. The added bonus of explaining how martial arts is still science is just gravy.

An hour and a half of a panel might seem a bit long or a tad dull to someone who's interests do not align with the material. However, I enjoy it. I am watching it. I think that if the old adage of "Monkey See, Monkey Do" applies to children watching their parents, my daughter might enjoy it as well.

I hope yours do.

Local History: Chain of Rocks Bridge: Water Intake towers.


You may have heard of the Great River Road along the Mississippi River. Rivers, like roads, are useful for transportation. The Mississippi river represents a very long and very wide river road from St. Paul, Minnesota to New Orleans, Louisiana. The river, however, can be temperamental. Of course, rivers don't have emotions, but high flood or low water could make great difficulties in navigating goods on the Mississippi. Some people hatched an idea to fix this; they wanted a reliable 9 foot navigation channel.

The Chain of Rocks area is called this due to some quirks of geology. During a period of glaciation, the Missouri River changed course. The old path was some distance into what is now Illinois. The new, and current path, cut over hard limestone which created ridges and shelves of rock that make navigation tricky. The river, at this point, looked like a chain of rocks at low water. 

To solve this navigation problem, the Chain of Rocks Canal was cut through Illinois in the 1940s for a length of 8.4 miles. The chain of rocks, the namesake of this area, are now usually submerged under water except for times of extreme low water due to a dam put in place to ensure the Chain of Rocks Canal had sufficient water. 

The Chain of Rocks Bridge, built in 1929 predates the cutting of the Canal by the Army Corps of Engineers. This bridge possesses a strange feature in that it takes a 22 degree turn along the way. This turn was a compromise between putting the supporting foundation of the bridge on firm ground and enabling fee access down the river in the years before the Canal was built. 

In 1967, Interstate 270 opened and the Old Chain of Rocks Bridge was retired. In languished in disuse for a while and developed a bad reputation for crime. Fortunately, Trailnet reopened the Old Chain of Rocks Bridge for pedestrian and bicycle traffic in 1999. From this location or while driving across Interstate 270 just north of the old bridge, you can see two 'castles' sitting in the river. 

A brief video clip from KSDK.com Goes into the towers and explains them.

These were water intake towers and were once a source of pride. Fresh and clean drinking water seems like a simple thing for us in this modern age. Not always so. "This was built in the time when having good drinking water, safe drinking water was something that the citizens bragged about and not all cities had it," -- Curt Skouby, Water Commissioner

Related to the delivery of water to the City of St. Louis are the various "towers" found throughout the city. One of these in the Compton Hill Water Tower. These were standing pipes of water that helped regulate water pressure in the days when steam power was used to push water to the citizens. Improvements have taken these land-locked towers out of use, but you can still visit the Compton Hill Water Tower and enjoy a nice view if you have good lungs and strong legs. If you wish to attempt such a climb, further details can be found on the Water Tower and Park Preservation Society's website.

Further Reading:
  1. Conor Watkins' Ozark Mountain Experience Article 4 Meet Me In St. Louis – Part II which disagrees with the video by implying the towers are still in use. Perhaps they were still in use when the article was written but have fallen out of use as indicated in the Video above.
  2. John Weeks III also provides a brief description of the Water Plant Intake Houses as well as a number of other articles under the heading of "Bridge Photography" and subheading of "St. Louis Area."  These include one on the Chain of Rock Canal and another on the Chain of Rocks Bridge.
  3. Builtstlouis.net provides some of the same information but has their own set of pictures which are very nice to look at.
  4. Some more background can be gleaned on the Chain of Rock Bridge itself from the respective Wikipedia Entry.
  5. City of St. Louis Water Division's entry on The Chain of Rock Plant might also be of some interest, although it doesn't specifically mention the intake houses.
  6. Another tangentially related aspect of water supply in the City of St. Louis involves the Standpipe Water Towers that appear at various points in the city. The City of St. Louis Water Division also provides some information on this as well.
  7. The Water Tower Preservation Society provides a history page specific to these one of these Standpipe Water Towers, the Compton Hill Water Tower. If you have good lungs and strong legs, you might want to visit.
  8. The Compton Hill Water tower is a St. Louis Landmark.
  9. Water Intake Tower #1 is a St. Louis Landmark.
  10. Water Intake Tower #2 is another St. Louis Landmark. [2]

The Amazing Meeting: Video: Eugenie Scott, "Playing with Deception" Science: 1/2 Hour Core Credit

The pursuit of education should be a life long love of learning. For this reason, and others, I generally do not look favorably on an education system that relies excessively on testing. Excessive testing spoils a child's enjoyment of education, does not impart that life long love of learning, and results in a system that educates more like the Hare than the Tortoise in Aesop's fable.

The Amaz!ng Meeting (TAM) represents one of the avenues for indulging in a life long learning process. Children may not be entirely interested in watching a person give a lecture, especially if they are not motivated to pay attention because there will be a test. However, I think there is some validity in asking my daughter to, as a homeschool student, watch these sorts of things.

Librarians and school teachers  stress the importance of a parent reading to their children every day. Apparently, reading to your children is one of the very best things you can do for your children. Reading for your own enjoyment and allowing the child to see you read also helps accomplish this. Children learn what they live, as an old poem used to go.

Children will mimic, mirror, copy, parrot, etc... those things that they see us doing. For me this is an excellent reason for my son and daughter to see their father interested in watching lectures as well as reading for my own elucidation. (My daughter is already aware that her father reads "old, college level books" as she puts it.)

Back to The Amaz!ng Meeting. (Wikipedia) The James Randi Education Foundation sponsors this meeting which focuses on science, skepticism, and critical thinking. Teaching our children to value traits such as these would serve them well in the life ahead of them. Truth does not simply fall out of the sky and land in our brains. Truth requires a devotion and a discipline akin to religion. Without skepticism, the mind falls prey to motivated reasoning, confirmation bias, cognitive dissonance, and other assorted pit falls.

If one would like to read further on an example of where the pursuit of truth sans rational rigor has run amok, I may suggest reading Sir Walter Scott's Letters on Demonology and Witchcraft. Reading is always Core Language Arts credit, but you might choose to label this as Social Studies and be not unfounded in your designation. 

Today, I would like to promote a video from The Amaz!ng Meeting in 2014 by Eugenie Scott entitled, "Playing with Deception." This video runs a convenient half hour duration and, coming from a conference devoted to science, skepticism, and critical thinking, you should be able to assign Core Science credit. I leave it to your own judgement if a test is required. A test can demonstrate that the student has payed attention and might provide motivation to focus their mind on the video. (Not everyone is self-motivated and self-directed.)

To that end, I am going to watch the video and provide a few questions that might suffice. You should watch the video yourself, I believe, to demonstrate to your student that the video and pursuit of knowledge in general are important for adults as well as children. If you do do, certainly, you can ask questions to highlight the parts of the video you, personally, found most meaningful. Should you do so, it would certainly be appropriate to comment to this article with your suggested questions.

Science: Videos: Supplementary Science from The Periodic Table of Videos.

A nice re-discovery, serendipity. 


At some point in the distant past, I must have found and "liked" a video and subsequently a page on Facebook. This page is called, "The Periodic Table of Videos." Obviously, this is the kind of thing that would be right up my ally, loving science and all. Still, I have absolutely no memory of this. Odd.

As it happens, the University of Nottingham had a fire recently. This story seemed newsworthy enough for Facebook to push to my news feed. Lo and behold, I find that they have a YouTube channel listing 500 videos of a reasonably short duration each. Still, seems like an excellent mass of science videos for a student wishing to continue to gain Core Science Credit.

Now, if I may make a suggestion. I think you could do as I have done and get your child set up on a Google Drive account. Then, as they watch the videos, they can record the video name, the time, and write a paragraph or two about the video. This would allow them some experience working a word processing document (GoogleDoc), some time with writing that also helps firm up spelling as Google Docs will underline spelling errors, some hands on the keys with typing (which is a useful skill to possess), and some Core Language Arts: Composition experience while also giving you some easily accessed "Examples of Work."

I'm going to talk to my daughter about it now.
