At least TWO | dependent variables independent independent variables are identified. are not identified. variables are identified. Is able to describe how to use available equipment to make measurements Is able to describe what is observed without trying to explain, both in words and by means of a picture of the experimental setup. Is able to identify the shortcomings in an experimental and suggest improvements 2 pts Adequate All chosen measurements can be made and all details of how it is done are clearly provided. 2 pts Adequate Clearly describes what happens in the experiments both verbally and with a sketch. Provides other representations when necessary (tables and graphs). 2 pts Adequate All major shortcomings of the experiment are identified and reasonable suggestions for improvement are made. 1.5 pts Needs Improvement All chosen measurements can be made, but the details of how it is done are vague or incomplete. 1.5 pts Needs Improvement A description is complete, but mixed up with explanations or pattern. The sketch is present but is difficult to understand. 1.5 pts Needs Improvement Not all aspects of the design are considered in terms of shortcomings or improvements. 1 pts Inadequate All chosen measurements can be made, but no details are given about how it is done. 1 pts Inadequate A description is incomplete. No labeled sketch is present. Or, adjusted to fit expectations. 1 pts Inadequate The shortcomings are described vaguely and no suggestions for improvements are made. 0 pts Missing At least one of the chosen measurements 2 pts cannot be made with the available equipment. 0 pts Missing No description is 2 pts mentioned. observations are 0 pts Missing No attempt is made to identify any shortcomings of the experimental. 2 pts Is able to identify a pattern in the data Is able to represent a pattern mathematically 2 pts Adequate The patterns represent the relevant trend in the data. When possible, the trend is described in words. 2 pts Adequate The expression represents the trend completely and an analysis of how well it agrees with the data is included. 1.5 pts Needs Improvement The pattern has minor errors or omissions. Terms proportional are used without clarity- is the proportionality linear, quadratic, etc. 1.5 pts Needs Improvement No analysis of how well the expression agrees with the data is included, or some features of the pattern are missing. 1 pts Inadequate The pattern described is irrelevant or inconsistent with the data 1 pts Inadequate The mathematical expression does not represent the trend. 0 pts Missing No attempt is made to search fora 2 pts pattern 0 pts Missing No attempt is made to represent a pattern 2 ptS mathematically Total Points: 16 force 50g .png 3 6 7 3 4 5 6 75 KB 4 5 6 V Show all 5 attachments (382 KB) & Save all to OneDrive - University of Nebraska at Omaha .
