Experimental Investigations 8 world Summary ? Scientific Inquiry Lesson Question How do scientists conduct scientific investigations? Answer (Sample answer) Scientists use the process of scientific inquiry to ask and answer questions about the natural world. To answer these questions, scientific investigations are done in different ways depending on the type of information to be gathered.
