1 Students have difficulty setting up their experiments. They make a few measurements of 10 full swings but do not collect sufficient data to make a meaningful scatterplot. Students are encouraged to speak with the teacher as soon as possible to review their work and to make a new start on the project. They graph the data that meet the generally accepted rules for stairway construction and the data collected for the project. They present their results in a report that includes their graph, table, and scale drawing.
All work is accurate and the report is well organized, clearly written, and interesting to read.
There are no mathematical errors in the report. 3 Student complete all aspects of the project and present their results in a report. Overall, the work is well done with some minor exceptions. The graphs, for example, are not entirely clear or the scale drawing could have been drawn better. The paragraph comparing local stairways' dimensions with the accepted rules for stairs is somewhat hard to understand.
