The
Blanket of Ash lesson was very interesting; I
could hardly believe what I was seeing. Looking
at a 1973 image was a great contrast to a 1983
image. The latter image was not as red, showing
less vegetation, I assume. I was not sure
whether the white particles were snow or lava. I
detected more rivers of lava in the later image,
as well as a larger volcanic opening, more
spread out. The lesson itself was good to see,
to see all the objectives, teacher preparation,
etc. It was a good sample to study. Some
mathematical applications might be studying
readings such as pressure, earthquake readings,
and temperatures occurring shortly before
eruption and comparing them to readings taken
several months before the eruption.
The El Nino lesson contained a similar format.
It was interesting to see the curriculum
standards. I also liked the web links where you
could go and learn more. The Standardized
Vegetation Index was quite fascinating, as it
showed the extreme conditions from one year to
the next. It was interesting how it illustrated
the flood conditions as well as the droughts,
and other climate factors effecting the growing
season. An interesting study might be to set up
some ratios between moisture in a given year and
crop production.
The Great American Desert utilized a DataSlate
featuring Garden City, Kansas. Again, it was a
new experience to see the Channel 2 labeling of
the different features. The Platte River,
Crescent Lake, test plots, and pivot irrigation
sites made it easier to visualize the study
being made. Of course, there was a great
implication for use of this in a statistics
class. The students could formulate a
hypothesis, conduct some tests on the data
collected in the spreadsheets, and make some
conclusions.
