Assignment to Write an Experiment Report Regarding Analysis of Physical Phenomena

Question

Learning outcomes
1.First of all:
The purpose of this assignment is to demonstrate that you can investigate and analyze physical phenomena by applying relevant concepts in practice and draw your own conclusions based on your own experimental data.

For virtual (computer-based) laboratories, you will be asked to perform experiments using online University of Colorado PhET simulations of experiments related to the module’s syllabus (e.g. “Mass and Spring”).

2. Learning outcomes:
   This assignment assesses your ability to: Demonstrate practical skills in using methods and adapting them to improve accuracy and justify changes. Accurately collect and analyze your own data. Draw conclusions and evaluate results based on scientific arguments.

Evaluation

3. Perform the method demonstrated by your class instructor (who will provide a method sheet and/or a “how-to” video available in the VLE), make your own adjustments to the method to improve accuracy, and produce an experimental report that meets your standards. Create. The evaluation criteria are as follows.

4. Goals: Your experiment goals will, of course, depend on which experiment you want your students to write for this final summative assessment. For a mass and spring vibration experiment, a good example of an objective would be.

Objective – Use algebraic and graphical methods to study the relationship between mass m and period of oscillation T and determine the value of spring constant k with uncertainty.

Five. If this procedure is performed in a laboratory/classroom, please include a risk assessment in your report.

6. Evaluation criteria: (40 points)
   Practical Skills (5 points): For face-to-face laboratory or classroom settings, practical skills are assessed in terms of how to set up and use equipment, apply error minimization procedures, and operational proficiency. Please return the equipment carefully after the experiment. For virtual (computer-based) laboratories, grades for practical skills are based on originality of ideas for improving methods, good results tables, and explanations of sources of error in evaluation.
7. For the virtual resistance lab: Micrometer screw readings must be correctly included in the appendix. Adjusting the method (2.5 points): A well-founded justification for the student’s own adjustment of the method to improve measurement accuracy. Additional note regarding virtual laboratories: It should be clear (at the latest) from the first line of the method that a computer-based laboratory was used.

Evaluation

Results (5 points): The results shown in the table and all other relevant results. Uncertainties and errors (such as instrument uncertainties, random errors, zero errors, etc.) that are all clearly, precisely and accurately recorded and correctly presented. For tables, column headings should include uniformity and uncertainty. The table should contain approximately 8 rows. No fabricated results!

Assessment report
Chart (5 points): Choose a descriptive title and carefully label both the x- and y-axes with quantities and units. Draw a best-fit line (do not connect the points) and measure the slope of the best-fit line itself (do not use the drawn points for the slope; do not use values ​​that correspond directly to the result table. please). If you calculate the slope directly, you should draw a large triangle on the graph to clearly indicate the accuracy of the slope calculation. If there is an abnormality, please circle it.

Analysis (10 points):

1. Comments on the shape of the graph, including comments on the value, intercept, and slope, and comments on anomalies (only if anomalies are present).
2. (a) Calculate the slope, and (b) use your own slope values ​​from your own graph to calculate the value you want (such as the spring constant k). All calculations must be 100% accurate and all steps must be clearly, detailed, and professionally entered (using the formula editor).
3. Perform a percentage uncertainty calculation as described in the VLE documentation on this topic.
4. The analysis section should include all three points mentioned above.

Conclusion (5 points):

Begin your conclusion by stating your final results. This must be presented in the correct format: k = (….. ± â€.) units. Then compare the result with the theoretically expected value along with the tolerance (use ± to find the two extreme values: is the value you looked at within the range?) Information on which the theoretical value is reliable Cite the source to show that it is from the source (provide a reference to the website or VLE of the book where you found the theoretical value in the bibliography). Finally, explain in your scientific report the main reasons why the results do not match 100% with the theoretically expected values ​​(what do you think are the main sources of error?).

Evaluation (5 points):

Please describe in detail what worked and what did not work for the measurements you performed and the equipment you used. Identify and discuss as many random and systematic errors as possible and list suggestions for improvements so that next time these errors and uncertainties can be minimized.

References (2.5 points):

Harvard University should be mentioned here. Please include any websites or books you used, such as: B. VLE (for virtual labs, you must specify the PhET simulation used), providing a source of theoretical expectations
