An educational psychologist is studying cognitive development in a cohort of young children (aged 5–6 years). They want to design an experiment to assess whether these children have developed the ability to conserve.
Describe two different types of conservation task, other than the conservation of liquid volume, that the psychologist could use in this study. For each task, clearly outline how the physical transformation is presented to the child.
