Lab Score: The lab score (25% of PHYS 211) will come from lab reports, activities, and end of semester lab exam which carries 25% of the lab score. Students need to register for one of the lab sections, PHYS 211L.

Guidelines for the in person laboratory: 

1.   You must read the lab-handout and the relevant materials from the textbook before the lab period and be prepared for the laboratory.

2.   You need to wear mask and follow social distancing in the lab.

3.   The laboratory equipment will be placed in the lab-tables, leave them as you found them when you leave.

4.   You need to handle the equipment carefully, giving special attention when warranted.

General Education Requirements: Listed below are the fundamental student learning objectives (1 and 2,3,4,6) for natural science courses as well as examples of how they will be fulfilled in PHYS 211 and PHYS 211L. Upon completing this course, students will be 

1. Conversant with the following classical physics concepts: mechanics (eg., kinematics, Newton’s laws of motion and gravitation, work, energy, power, rotational motion), fluids (eg., Archimedes’ principle, Pascal’s principle, and Bernoulli’s principle), wave motion, and sound. This competency will be assessed using homework, tests and final exam. 

2. Able to apply the scientific methodologies of inquiry. (e.g., In the co-requisite laboratory, PHYS211L, students will use scientific methods of inquiry to design and perform experiments and investigations). The students’ ability to fulfill this requirement is assessed using their lab reports. 

3. Able to discuss the strengths and limitations of science. (e.g., In the co-requisite laboratory, PHYS211L, students will use experimental error & accuracy during experimental design and data collection & analysis). The students’ ability to fulfill this requirement is assessed using their lab reports. 

4. Able to demonstrate an understanding of the history of scientific discovery. (e.g., topics and devices are introduced with historical perspectives. They will see how the scientific advances made in a laboratory transform into useful technological devices: development of the transistor from vacuum tube to silicon chip). This competency will be assessed using tests and final exam. 

6. Able to communicate about scientific subjects including (lab courses only) the defense of conclusions based on one’s own observations. (e.g., In the co-requisite laboratory, PHYS211L, students will write well-reasoned conclusions based on data and analysis of their experiments and investigations). The students’ ability to fulfill this requirement is assessed using their lab reports.

How to write a conclusion?

* Conclusion is the most important part of your lab write-up. It is a summary, about a page or two, depending on the number of data tables and graphs. You must write your own conclusion, after completing the data collection and analysis. The data tables and graphs must be inserted at appropriate places. The conclusion section is the part of the lab which is most important to check for student comprehension of the topic. Even though you do the lab and collect data as a group, you should write your own conclusion. 

* Conclusion should state things that are unique for your investigation which can be accomplished by including values of the experimentally determined physical quantities.  Just remember that you cannot write your conclusion without completing your experiments or investigations. General statements like "I have determined the densities of given solids" and "Human Error" are not acceptable.

Start your conclusion by re-stating the purpose with appropriate changes. Then you need to briefly state (don’t repeat procedure) how you conducted the experiment and collected the data. Continue this with summarizing your results, referring to the inserted data tables and graphs when appropriate, and answer the purpose. State things that are unique for your investigation, which can be accomplished by listing important values of the experimentally determined physical quantities. Then you need to discuss about some of the difficulties you had, errors and their possible causes (be specific, human error is not acceptable) and suggestions for improvement. Describe your reasoning using physics terminology and principles. You should explain as completely as possible what goes through your mind that leads you to your conclusion.
