EAST CLEVELAND LEADER
studying about the various
parts and tissues of the body
all of which are made up of
complex and extremely tiny
cells.
Naturally the children were
curious to see some real cells.
1t happened that one of the
boys in the room had a micro
scope at home, whose resolving
power was sufficient to show
human cells clearly. So he was
asked to bring it to school for
the children to look through.
Well, the boy returned to
school bearing his microscope.
The next thing to do was to
get some cells to look through
it. For this purpose, it turned
out, one of the best things to
use is a little bit of human
blood.
The children in Mrs. Strug-
giles room had anticipated this
contingency, and one of the
boys in the class had volunteer
ed to supply the necessary in
gredient. But when the micro
scope was there, and the glass
plate ready to receive the blood,
and the sterilized needle dipped
in alcohol prepared to extract
same from one of his thumbs
well! The sun may have been
shining, but it was a dark mom-
ent for him!
So, in the interest Of science,
the teacher decided that the
experiment h hould not be
brought to a halt because of
the lack of one little ingredient.
She therefore applied the needle
to her own thumb, and the ex-
pertinent continued without fur
ther interruption.
The children thought they
could even see some cells divid-
ing, but they couldn't be sure.
What often happens is that any
particular cell is hard to keep
in focus with the microscope
fixed at a particular setting on
a particular spot; but they had
learned in their studies that
this division goes on all the
time in living organisms.
Bioscope Used
At Chambers
The other microscope story
comes from the Hard of Hear
ing School at Chambers. Their
instrument, however, is of a
different kind. Called bio
scope, it can be used in either
one of two ways.
A bioscope can be looked
through in the same way as a
regular microscope can, or it
can reflect the magnified image
Of the object on vertical
screen for a roomful of stu
dents to see. 1t was in this sec
ond position that the Chambers
bioscope was being used last
week, for the older students in
Miss Alice Kent's school to
observe living, transparent OBJ
jects.
The children had some zebra
fish to watch. Zebrafish are so
tiny that they can't be seen
at all with the naked eye, al
though a magnifying glass will
pick them up. With the aid of
the bioscope the students could
see the miniature fish even
more clearly; they could watch
their hearts beat, and could
make out their fins and mouths.
They also observed some
snail eggs, and were able to see
the tiny embryos moving inside
the eggs. Both these and the
zebrafish were just as alive
and normal as the scores Of
others like them in the schools
aquarium, and did not have to
be treated or prepared in any
way for the children to watch
them.
Plan Visit to
Historical Museum
The third graders at Called
onia School are planning a visit
to the Western Reserve Histor-
ical Museum at University
Circle, as a elimination Of their
Social Studies unit on pioneer
life in early Cleveland.
They will be able to see the
furnishings. tools and other
handicraft that they have been
studying about in their class
rooms, and will listen to expert
enced guides tell them many
more facts of interest about the
