International Technology and Engineering Educators Association - TechnologyĬompound machines are two or more simple machines interacting with one another to do work. Recognize that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number. Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered. Summarize numerical data sets in relation to their context, such as by:ĭescribing the nature of the attribute under investigation, including how it was measured and its units of measurement. Specification of constraints includes consideration of scientific principles and other relevant knowledge that is likely to limit possible solutions.Īll human activity draws on natural resources and has both short and long-term consequences, positive as well as negative, for the health of people and the natural environment.Īlignment agreement: Thanks for your feedback! The uses of technologies and any limitations on their use are driven by individual or societal needs, desires, and values by the findings of scientific research and by differences in such factors as climate, natural resources, and economic conditions. The more precisely a design task's criteria and constraints can be defined, the more likely it is that the designed solution will be successful.
This activity focuses on the following Three Dimensional Learning aspects of NGSS:ĭefine a design problem that can be solved through the development of an object, tool, process or system and includes multiple criteria and constraints, including scientific knowledge that may limit possible solutions.Īlignment agreement: Thanks for your feedback! Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.Ĭlick to view other curriculum aligned to this Performance Expectation
