Christopher wanted to learn about Jupiter's moon Ganymede and the best source of information would be a university's astronomy web page. Taylor made some observations and wants to answer a question, so she should analyze evidence, draw conclusions, and communicate results. Joseph wonders what kinds of birds live in his neighborhood and will use observation to investigate. The main reason scientists conduct investigations is to answer questions about the natural world. Scientists sometimes replicate other scientists' research to verify the work is accurate.
