Whatever experiment scientists do, when they make a mistake they obviously need to do the whole experiment again!
Making observations
Making observations
is studying, collecting data and recording relevant information. These observations are based on the scientist's senses and are typically objective and unbiased. The scientist may use various tools and techniques to aid in making accurate observations.
It is more like trial and error. They make the experiment more accurate by the correct measurements and making sure they are using the correct equipment. When something goes wrong they simply repeat the experiment, to make the experiment improve.
