Investigating Gravity 4 Students follow the key steps stated in the text to collect their data. All calculations and graphs are accurate and explanations are clear and correct. A complete and well written report summarizes the experiment and states the relationship between distance and time correctly. 3 Students collect their data, make the necessary plots, calculations, and graphs, and write a report of their work. Each aspect of the work is done correctly, but the graphs could have been drawn more neatly and the description of the procedure in the report is too brief.
Students describe the relationship between distance and time correctly.
2 Students complete the experiment by collecting their data, drawing and comparing graphs, and writing a report. 1 Students set up their ramps but do not record the time and distance for ten starting points accurately. The scatterplot of the data is not representative of the real situation. A report is not written. 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.
