is a web delivered simulation of acid base chemistry
laboratory experiments suitable for middle school
It has been developed for the needs of the Secondary
Education in Greece as a small part of a multimedia
educational system developed for the Pedagogical Institute.
The students can freely experiment with solutions
of acids, bases and salts. The experiments could be
the use of indicators, pH paper and pH meter for the
measurement of the pH of a solution, the effect of
dilution on the pH and the acid - base neutralization.
Several modules of juniorLAB have been developed in
order to fit the instructional needs of teachers.
A few of them are presented here.
