Physics 241 Lab – Matt Leone – [email protected] (email always preferred), PAS 463Lab Webpage: http://bohr.physics.arizona.edu/~leone/ua_spring_2010/phys241lab.html Office Hours: Monday 3:00-5:00 in PAS 463. Consultation Room - free tutoring in PAS 372 (also a good place to meet to work).Policies for threatening behavior by students: http://policy.web.arizona.edu/~policy/threaten.shtml Students with special needs who are registered with the S.A.L.T. Center (http://www.salt.arizona.edu/ ) or the Disability Resource Center (http://drc.arizona.edu/ ) must submit appropriate documentation to the instructor if they are requesting special accommodations. Also refer to the Physics 241 Policies handout on page 6 of the lab manual.Summary of laboratory policies in order of importance: • 10 of 12 lab reports required or you automatically fail the whole course. No labs are dropped.• Labs are due in class (emailed lab reports are not accepted). -25% for each day late.• Excused absences are only possible with valid documentation (speak to your TA in advance if possible). No makeup lab can be given without legitimate documentation.• Use the provided writing guidelines in each handout. This will help you immensely in quickly writing a good report.• Labs are full so you must come to the lab you registered for (speak to TA in advance).• Cheaters/plagiarizers are always caught and such actions are recorded on their college transcripts, which can ruin future opportunities. Don’t do it!o Leave with your own data and write your report by yourself.o All graphs must be hand drawn so get them done DURING lab.o Don’t use text/wording from the internet or the lab manual. Restate all ideas in your own words.o Don't use pictures from the internet. If you want to add pictures, either leave blank space in your text and draw them in or use a digital camera.• ADVICE: Set up D2L to forward to your gmail account (or other inferior webmail account).

Reports are broken down into different sections, and each section is worth a certain amount of points (point values for sections will change based on the nature of each lab but approximate values are given below). Each week I will give instructions on writing the sections of your report that are unique to each lab. USE THE FOLLOWING SECTION TITLES AND LABEL THEM IN YOUR REPORT. Here are the sections you will need for each report with their approximate point values:• Title. Not worth points so make it fun!• Goals. Describe in 3 or more sentences what the BIG IDEA was for the lab. What was the heart of the matter? What basic principles were you studying experimentally? (~1 point)• Concepts & Equations. Often the biggest section. Describe the physics concepts studied in this lab. Describe the mathematics used to model these concepts. If you use a formula to calculate something, you need to explain the meaning of the formula and may need to show a derivation or an example calculation. It is often easiest to leave black areas in your report and write your equations into the final printout (which takes some organization, try numbering your equations). You must write using sentences & paragraphs; bulleted lists are unacceptable. (~5 points) • Procedure. Tell what you did in general terms. You should provide labeled sketches of equipment/apparatus for any new equipment not described in previous reports. You do not need to give every specific detail. If your procedure seems too long, it probably is. Make labeled sketches by hand and attach them to your report, or simply leave blank areas in your report and draw in your diagrams to the final print out. You must write using sentences & paragraphs; bulleted lists are unacceptable. (~2 points)• Results. This section is where you quickly report what you found in a “robotic voice”. Do not type in your raw data; making reference to graphs & tables made by hand during class are fine. Simply report what you observed for each section of the manual and discuss any qualitative or quantitative errors associated with the data. Save discussion of the meaning of your results for the conclusion section. For example, if you measured the same quantity 10 times, you might report the average found and any measurement error. You should report what your observed in your graphs; ex. “the voltage increased logarithmically with distance as show in Graph Name”. You must write using sentences & paragraphs; bulleted lists are unacceptable. (~2 points)• Conclusion. Describe the meaning of your results in terms of the concepts & equations you described earlier. Describe how what you found experimentally relates to the big idea you described in your goals. It is all right to sound repetitive since in scientific writing you want to make sure your ideas come across. This section could be said to connect the Results section to the Concepts & Equations sections. Do not write personal statements like “I enjoyed this lab” or “ this lab was beneficial to my understanding of…” Keep it concise and scientific. You must write using sentences & paragraphs; bulleted lists are unacceptable. (~5 points)• Graphs. Graphs must be neatly hand-drawn during lab and stapled to your lab report. Your data must fill the entire page (requires planning ahead). You graphs must include: a descriptive title, labeled axes, numeric tic marks on the axes, unit labels on the axes, and the line of best fit written directly onto the graph (if necessary) as in “V(t) = 3.25t + 7.10”. (~5 points)• Handout. The thoroughly completed in-class worksheet signed by your TA stapled to your report. (~5
