You obviously know that we have a lot of earthquakes here in California.
Well when I was a young child I grew up here in California and
I was home alone during a very large earthquake.
The whole room shook, the windows rattled.
It was just frightening. The sounds of everything shaking in the house
were really scary such that for years afterwards every time I heard
a custodian at our school with a a trash bin that he wheeled along, every
time I heard that
rumbling sound, it reminded me of the rumbling that my building
made when I was sitting there at home alone in that room.
So it scared me for quite a while, but it really think about it until
I got to high school going to college and then my second year in college
I finally took a geology class.
I said "hey! I get the finally figure out
what caused all that shaking
and all that rumbling." All that stuff that scared me. I was really excited
figure that. I thought, "hey knowledge is power!"
And today one of the things that I'm still very interested in is I'm trying to
figure out
how we can make things safer for people during earthquakes.
We want to be able to predict them... Maybe we can't do that,
but maybe we can study earthquakes and understand them well enough that we can
actually
figure out how to make things safer for them. The way that we're going to start that
with our very first unit is understanding
the earthquake machine; how earthquakes work.
And you're going to see a video of this a little bit later. You are going to play a lab
with this on the computer.
Right now all this go ahead and give you a start. We turn the crank.
Earthquakes happened as i turned the crank.
What does all this represent? Well, stay tuned for this VoiceThread and we'll
figure it all out!
