Employ simple equipment to gather data This addresses
Standard A
Have students collect a variety of small items. These could
be stones, paper, thread, (let them use their imaginations)
Have students measure using simple rulers(a good refresher
on measurement if necessary or the time to teach it) weigh
the objects, examine under the Blister viewer, write down
the data(students do if old enough to do this) record descriptions
of texture, color, etc. seen while examining items with microscope.
Blister slides can be useful here for containing and viewing
some items. Inquiry can also involve drawing or tracing around
the items. Do your students keep Science notes?
It is easy to extend with class discussion with older students
to address another Content Standard.
Part of Standard E is *Distinguishing between natural objects
and people-made objects.
This activity can be expanded for older students to become
cross-curricular to Social Studies to investigate where in
the world the items may have come from.

The
Blister Electric Microscope was developed as a tool for Science
Education. Since 1946 the General Science Blister Viewer has
filled that need for schools and individuals. Because of its
wide field, relatively low power(50X) and built in light it
is easy to operate and allows viewing of opaque objects which
normally cannot be viewed by a conventional microscope. 
Blister
Viewers also work well for viewing slides and organisms. In
fact the patented Blister slides and culture chambers were
developed for this purpose. Blister microscope slides and
chambers are heat formed of clear vinyl.
