22.214.171.124.2 Recognize that when scientific investigations are replicated they generally produce the same results, and when results differ significantly, it is important to investigate what may have caused such differences.
126.96.36.199.3 Understand that different explanations for the same observations usually lead to making more observations and trying to resolve the differences.
188.8.131.52.4 Understand that different models can be used to represent natural phenomena and these models have limitations about what they can explain.
2 Scientific inquiry requires identification of assumptions, use of critical and logical thinking, and consideration of alternative explanations.
184.108.40.206.1 Generate a scientific question and plan an appropriate scientific investigation, such as systematic observations, field studies, open-ended exploration or controlled experiments to answer the question.
220.127.116.11.3 Conduct or critique an experiment, noting when the experiment might not be fair because some of the things that might change the outcome are not kept the same, or that the experiment is not repeated enough times to provide valid results.
3 Interactions Among Science, Technology Engineering, Mathematics, and Society
2 Men and women throughout the history of all cultures, including Minnesota American Indian tribes and communities, have been involved in engineering design and scientific inquiry.
18.104.22.168.1 Describe how science and engineering influence and are influenced by local traditions and beliefs.
4 Tools and mathematics help scientists and engineers see more, measure more accurately, and do things that they could not otherwise accomplish.
22.214.171.124.1 Use appropriate tools and techniques in gathering, analyzing and interpreting data.
