refine the design accordingly. Plan and conduct an investigation or test a design solution in a safe and ethical manner including considerations of environmental, social, and personal impacts. Evaluate different ways of observing and/or measuring a phenomenon to determine which way to answer a question. Evaluate appropriate methods and/or tools for collecting data. Evaluate the accuracy of various methods for collecting data. Select appropriate tools to collect, record, analyze, and evaluate data. Make observations (first-hand or from media) and/or measurements to collect data that can be used to make comparisons. Make observations (first-hand or from media) and/or measurements of a proposed object or tool or solution to determine if it solves a problem or meets a goal. Make predictions based on prior experiences. Make observations and/or measurements to produce data to serve as the basis for evidence for an explanation of a phenomenon or test a design solution. Make predictions about what would happen if a variable changes. Test two different models of the same proposed object, tool, or process to determine which better meets criteria for success. Collect data to serve as the basis for evidence to answer scientific questions or test design solutions under a range of conditions. Collect data about the performance of a proposed object, tool, process, or system under a range of conditions. Make directional hypotheses that specify what happens to a dependent variable when an independent variable is manipulated. Manipulate variables and collect data about a complex model of a proposed process or system to identify failure points or improve performance relative to criteria for success or other variables.
