5 teaching strategies central to this course are activated is the pendulum lesson

learning cycle --- learning cycle
exploration: ride in car
concept intro: inertia: pendulum mechanism
concept apply: inertia in other settings

should parents be jailed if their child is killed because she wasn't "buckled up" and the state laws says that they must be ?

the most important concept of human interaction in the whole wide world

"when you leave your bedroom each morning ... and come out to "play" with the rest of the world, you have to begin surrendering your 'rights' "

good news: if you die, your family pays for the burial

bad news: if you are bloodied I help pay for the hospitalization

should I have to pay for your stupidity ?

Swiss: no belt = no insurance

science = inertia
s-t-s technology = belts / air bags
society = people's rights / insurance laws

process science

interpreting data --- seatbelts have saved ...

311 jillion teeth
868 million noses
l82 billion fingers
300 million jaws
444 billion ribs
164 zillion lives

vs. perceptual psychology

"but my neighbor's aunt knows someone who said that their brother's girlfriend was in an accident and if they had been in their seat belt ... they may have died."

threats don't matter -- they don't work -- and don't change behavior

discrepant event

make the pendulum go faster
what variable to change ?
length of string
or push
add weight
or change size of arc

discrepant event: part ii

helium balloon in car
geez: even AIR has inertia

perceptual psychology:

if you don't precieve the problem --- there is no problem

processes

observing
measuring
collecting data
making a graph
predicting
hypothesizing

when I was still pretty young
I don't know how old exactly
I had a ball in a wagon I was pulling ... and
I noticed something, so ...
I ran up to my father to say that ...

"When I pull the wagon, the balls runs to the back, and when I am
running with the wagon and stop, the ball runs to the front. Why?"

how would you answer ?

he said, "That nobody knows!"

he added,
"its's very general tho, it happens all the time to anything;
anything that is moving tends to keep moving;
anything standing still tries to maintain that condition.
if you look close, you will see the ball does not run to the back of the wagon
when you start from standing still.
it moves forward a bit too, but not as fast as the wagon.
The back of the wagon catches up with the ball ...
which has trouble getting started moving.
It's called inertia, that principle."
I did run back to check, and sure enuff the ball didn't go backwards.
He put the difference between what we call it (and what we see) very distinctly.

synectics SYN = putting things together
that don't belong together
just to see how much they belong together
