.Microscale
chemistry experiments with disposable materials (syringes, injection
bottles, dropper bottles, plastic pipettes) were first published by El
Marsafy. Microscale in this context means the volume range between
5 µl (micro drop) and some ml.1988 he introduced these worldwide
available materials into pre-service teacher training at Ain Shams University
Cairo. For quantitative experiments the students had to bye two-pan
scales, a thermometer and a digital multimeter.
Insulin syringes allow titrations I with
an accuracy sufficient even for high schools.
MicrEcol uses the
same materials and quantities of matter. It is adjusted to children and
younger students.
Even in Kindergarten
or at home with their parents the explore their environment (water, air,
food, soil, fuel).
For home experimentation of
students a written approval of the parents is necessary. So they are responsible
for proper supervision. Most of the substances needed are chemicals of
the daily life. Even for the microscale experiments prescribed in this
homepage all safety precautions must be
observed. No experimentation without goggles! Students
and other interested readers are welcome to visit the site to learn more
about chemistry. Individuals performing the experiments described herein
accept full responsibility for all that results directly or indirectly
from these activities. The authors shall be absolved of any and all responsibility
for the result of activities conducted from information and instructions
