Abstract
This study was conducted to answer a few research questions about the conservation of number, mass, length and volume among four groups of 7.5 and 10.5 year old girl and boy primary school pupils in Zahedan.
The sample cosisted of 120 second and fifth grade pupils of Zahedan who were selected randomly and equally from 7.5 and 10.5 year old populations. The project clinical method was usedto measure conservation.
Data analysis showed that: a) 10.5 -year- old girl and boy pupils performed better than younger pupils in all four types of conservation and their components: prediction, judgernent and explanation; b) there were no differences between girls and boys regarding the four types of conservation investigated; and c) children achieved conservation of number, mass, length and volume successively.
