It's impossible in this country to
traverse middle school without a thorough examination of the scientific method,
which usually involves multiple full on projects, topped with presentations. Most of us have studied the scientific method more extensively than the
Constitution, the seminal document written by the founding fathers that defines
your rights as a citizen. People in this country learn the Pledge of Allegiance
to the scientific method all through middle school.

It's great that everyone has to
learn about the scientific method so we don't have to argue arcane stances
against creationism or intelligent design. We can simply pull out our
scientific method banner and march, lock step, over anyone who doesn't agree
with our well-formed, thoroughly researched, extensively tested hypotheses. The
only issue I have with the middle school infatuation with the scientific method
is that most of us in the course of our daily activities for better part of our
entire life will never have need for the scientific method. What we more likely
will need to do is some form of reengineering.
Now, reengineering is likely
something you didn't study in middle school. Simply put, reengineering is
figuring out how something is made, how it was assembled, how it works. You
reengineer something for a very important reason, to fix it. A lot of things are going to break
in your lifetime, and being able to fix things is a valuable skill. Calling in
the trades every time something doesn't work is an expensive
proposition. If you own a house, a car, a boat, a computer, a bicycle, anything you got to
be able to fix things.
A good example is a 3-way switch
which is used when you have a need to turn on a light from more than one
location. I'm sure you have a 3-way circuit in your house. My son, Aidan, did
in the science room in sixth grade. There were two doors in the science lab
with light switches at each. The simple circuit for a switch and a light looks like
this,
Obviously if you have two switches at different locations you need something more in the wiring and switches to allow one switch to operate independently of the other. Understanding how this works is crucial to repairing a 3-way circuit. You can call an electrician, but it will cost you a minimum of $400, or you can fix it yourself in about twenty minutes. Your choice, Einstein.

When it came to the science fair,
Aidan became very interested in the operation of a 3-way circuit. He wanted to
teach his friends how to set up the circuit given wires and switches, a battery
and a light. Commensurate with his
generation, he developed a simulated three way circuit in Minecraft, a popular,
creative building, sandbox video game.
His teacher initially rejected his
proposal on the grounds that it didn't follow the scientific method. He asked if
she knew how a 3-way circuit worked. She didn't. True, he wasn't purposing a possible solution
to a problem plaguing mankind, but if you ever worked on one of these circuits without
knowing what you’re doing, you know how difficult it is to get the wiring
right. There are six connections to be made which offers you 720 possible combination with only two of them being correct.
After some negotiations, he managed
to convince Madam Curie to let him proceed. He did a fantastic job explaining
how a 3-way switch is actually a logical OR gate. He traced out the circuit from the power source
to the light for each switch position. He even called his presentation The Or
Gates Around Us.

Second place was a girl with an
orange and some litmus paper. As far as I could tell, she was technically
correct with all her findings. It's just not very hypnotizing to hypothesize that dipping litmus
paper into a glass of milk would give a neutral response, however true. Not bad, Rachel Carson.
Third place was a balloon on a
string. The hypothesis was that when the clothespin was removed, the balloon
would zoom along the string. Since tape was used to form a loop through which the string passed through, when the clothespin was removed, the balloon popped. Good enough for
third place, Orville Wright.
Aidan got "honorable
mention" because he didn't follow the scientific method. The
kid who won didn't either, but when you got electric bolts shooting across the
classroom and students hair standing on end, you got a winner with or without the scientific method.
I know what you're thinking. I'm a
disgruntled, snowplow parent, who's annoyed that my son didn't win. That's
what a friend of mine told me. He's probably right. The other day at his house,
I flipped a switch, and he said,
"Don't touch that switch. If
you do, the other switch over there won't work anymore."
Aidan said,
"The travelers are hooked to the
wrong screws."
He was right. I took out my Swiss
Army knife, and he and I wired the switch up correctly. I don't know much about
snowplows, but if I had a problem with mine, my son and I would certainly figure out how
to fix it.
