Piaget Conservation Of Mass. Conservation of mass and length occurs around age 7 conservation of weight around age 9 and conservation of volume around 11. Piaget described several conservation experiments.
To illustrate this piaget used greencardboard to represent farmland. Most children aged seven could answer this correctly and piaget concluded that this showed that by seven years of age children were able to conserve number. Conservation of mass and length occurs around age 7 conservation of weight around age 9 and conservation of volume around 11.
Several physical quantities are unchanged or conserved in the face of spatial or configurational transformations.
The seven piagetian conservation tasks. Conservation of mass and length occurs around age 7 conservation of weight around age 9 and conservation of volume around 11. In the first stage children do not yet have the ability to conserve. A second ball of clay the same size is shown to the child who agreed they were equal.
