What makes a good scientific question is that it can be answered by direct observations or with scientific tools. They state the final question in a way that can be answered by investigation or experiment. A good scientific question is: “What effect does the pH of water have on radish seed germination?”

How scientific knowledge is created?
Scientific knowledge is advanced through a process known as the scientific method.
