Data (5 pts)

код для вставкиСкачать
1. Reports should be typed on plain white paper. The graph may be done by hand on graph paper or created using Excel, Graphical Analysis, or the website 2. An appropriate and descriptive title should be centered at the top of the first page.
3. Each of the following sections of the laboratory report should be included, in order, and identified by name:
Purpose (2 pts)
This is an "if - then" statement or question that provides overall direction of your investigation. The independent and the dependent variable will be defined here. This purpose should be addressed in your conclusions. This should be well developed, i.e. more than 1 sentence. Why are you doing the research? What do you hope to accomplish?
Equipment (1 pts)
The equipment should be clear and detailed enough so that someone who was not present during the lab can gather the same equipment that you used. It should be a bulleted list. You might include a detailed and labeled diagram to illustrate the configuration of equipment, if it's hard to understand. This diagram may be done electronically with a digital camera or in a paint document. This diagram may also be drawn by hand.
Procedure (5 pts)
This is a written explanation of how to do the investigation. The procedure should be clear and detailed enough so that someone who was not present during the lab can understand and reproduce the experiment with similar results. This should be a simple step by step list.
Procedure checklist:
1. Does your procedure control the experiment adequately so that other variables do not significantly influence the results?
2. Do your procedures allow for the collection of an adequate range of data?
3. Do your procedures allow for an adequate number of trials?
4. Do not include basic skills detail (i.e. do not explain how to operate a stopwatch)
Data (5 pts)
This is an organized presentation of the data obtained in the experiment. This would include: all raw data measured directly in the experiment and calculated values. Data Table checklist:
1. Title
2. Clear/meaningful headings for each column/row
3. Units for any measured quantities
4. Independent variable is usually in first column/row; dependent in the others
5. All data neatly organized into columns and rows (only one type of data per column)
6. All data reported (don't just report averages!)
Data Processing/Analysis (5 pts)
For any calculations that are done, one example should be shown. This section also includes all graphs (titled and appropriately labeled) made from the data obtained. Once again, the graph may be done by hand on graph paper or created using Excel, Graphical Analysis, or the website Graph checklist:
1. Title
2. Clear/meaningful headings for each axis
3. Units for any measured quantities
4. Appropriate variables plotted on the x-axis and y-axis.
5. Properly spaced scales on each axis (good rule of thumb: fill 3/4 of space)
6. Data points plotted accurately
7. Smooth line or curve of "best fit" drawn through data for a line not play connect the dots! 8. A key is used if more than one data set appears on the graph
Conclusion and Evaluation (7 pts)
What happened in this lab? Summarize your findings. Use your data (cite specific examples) to support your findings. Discuss any questionable data or surprising results. Explain the possible sources of error (things that may have gone wrong) in the experiment and specifically how those sources influenced the data. Discuss any implied meaning or relationships that exist among the variables of the experiment. Suggest changes in experimental design that may reduce the identified sources of error.
Conclusion checklist:
1. Concluding statements address the original purpose and are supported/justified by evidence cited from data
2. Sources of experimental error are analyzed
3. Realistic experimental improvements are suggested in respect of errors.
