8 Fill in the blanks with the following thinkingconclusionsScientists often have to evaluate scientific explanations in two parts. Scientists evaluate the observations that are made, and evaluate the made from thoseobservations. To make a decision, scientists use their skills to evaluate the evidence. Scientists have to be careful whenever they are collecting any type Measurements must be accurate and instruments must be properlycalibrated, as scientists cannot afford to be careless in their data scientific explanations must be by other scientists. If a scientist s experiment cannot be recreated accurately by other scientists, it might mean that theexperiment is invalid.

9 Once the experiments and evidence have been tested and examined, the scientist might draw based on the observations. However, when drawing conclusions, scientists should ask themselves if they considered all of the possible It is important to keep an open mind when drawing conclusions fromscientific information. It is also important to remember that scientific information is constantly , and that all scientific models are subject to is important to know that scientific reasoning is used not only in the Scientific reasoning and critical thinking skills are used every skills will help you claims and make good decisions about theworld around :Answer the following questions on the lines is it important for a scientist to write down every observation, including unexpectedobservations?
