Sometimes kids don't ask a question in school because they assume everybody else knows the answer, but kids who grow up in households that encourage inquiry have a head start. You can help your child feel comfortable asking questions by asking plenty yourself. Problem solvers (and scientists) are people who want answers and are not afraid to ask. Try asking your children simple questions to get them thinking like a scientist: Why do crabs have shells? Why do tables have four legs? Challenge your children to think of other mind-stretching questions and join them in brainstorming possible answers.
