NASA Why? Files segment explaining the Data Matrix, a logical way of charting observations in an experiment.
Hi, Dr. T!
00:00:00
Hi! What do you have in your hands?
00:00:02
The official weather map from Craig Moeller.
00:00:04
The weatherman?
00:00:08
Yes, the meteorologist.
00:00:09
Bernie and Jerome will recognize the name.
00:00:10
We know now who smells the stink each day,
00:00:13
and maybe now, with the wind direction,
00:00:16
we might be able to figure out the source.
00:00:19
I'm so confused!
00:00:22
How in the world do we make sense of this?
00:00:24
I'd suggest you put all your information in a chart form,
00:00:27
what we call a matrix.
00:00:30
It may help you organize all this information.
00:00:31
I've already made a matrix.
00:00:35
It has the days of the week across the top
00:00:37
and the four cities down the side.
00:00:39
Your job is to mark when each city smelled the stink each day.
00:00:41
Later, you can compare the wind direction on each day
00:00:46
to your chart and to the map you've already made
00:00:50
to see what it might mean.
00:00:52
Oh, cool! I think this will really help us!
00:00:54
Let's go back to the treehouse and try it out.
00:00:57
Thanks, Dr. D!
00:00:59
Bye!
