Two examples are included in the video and two additional examples are included in the linked thinking slides. TERMS Conduct- investigate phenomena using scientific methods. Data - measurements or statistics used for evidence Directional Hypothesis - uses an explanation to predict specific outcome of experiment Ethical - relating to moral principles Evaluate - to determine the significance of by careful study Investigation - a searching inquiry for obtaining facts Phenomenon - observable events in the natural world (require explanations) Plan - to create activities for something Prediction - to say that an event will happen in the future Purpose - the reason for which something is done or created Refine - to improve by making small changes Reliability - consistently good in quality Safety - ensure responsible experimental practices avoiding harm Variable - a factor that can be changed, controlled or measured Controlled - factors that are kept constant during an experiment Independent - the manipulated variable in an experiment (cause) Dependent - the responding variable in an experiment (effect) This progression is based on the Science and Engineering Practices elements from the NRC document A Framework for K-12 Science Education. “Plan and conduct an investigation to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.” Source: https://www.nextgenscience.org/
