This document discusses different methodological approaches to researching children's lives, including experiments, surveys, interviews, and ethnography. It notes that all research with children involves ethical issues regarding informed consent, parental permission, risks and benefits. Experiments aim to test interventions and individual differences, often using deception, while surveys collect data from parents and children through questionnaires. Ethnography aims to understand children's cultures by observing them without preconceived hypotheses. The document examines specific studies that use these methods to research children's grief and cultures. It raises questions about whether adults can ever truly understand children's perspectives without biases.
