All rights reserved. If the student is to have ownership of an investigation, perhaps she should help define the question being investigated. Invariably they begin with their own excitement about a given problem, ask fascinating questions about the concept or material in question, and then create a series of activities that help answer their questions. The problem is, of course, that they are working with their questions. Also, students should be helped to distinguish between those questions that can be meaningfully posed and answered within science, and those other nonscientific questions that are outside the purview of science.
