1 LABORATORY EXERCISES 1.1 Description of Labs There will be five labs and one computer simulation in the fall semester. These labs will be performed independent from class time. You will work in groups of your choice that are not larger than four members. The data collection aspect of these labs must be performed during the 1 ¾ -hour lab period offered Monday to Friday after school. Analyses can effected in any location of convenience to you and your lab group. The details of the experiments and the project will be made clear when this document is released to the class on the first day of school. Full use of your graphing calculator, Maple, Excel and possibly some programming will be necessary to complete some of the analysis required for these labs. Here is your chance to be a scientist! You are expected to design the procedures and analysis for each experiment. You will be marked on how well you first conform to the requirements of form and the basic academic constraints of the experiment and then on how you handle the more subtle and technical aspects. This is a measure of your scientific acumen and creativity. Yes, you can do more, but does it really contribute to the experiment? You need to weigh all of this very carefully. You will not have time to waste in your laboratory experience in university (or professional life) so find ways to check that you are on the right track before you waste a lot of time. 1.2 Lab Paper Submissions Policy Below you will be deadlines for the submission of the formal report for each lab experience. To save paper and facilitate archiving the submission policy is being changed for class 1112. This year the submission policy requires ONE hardcopy and one soft copy in .pdf format. The soft copy will be archived. The soft copy MUST be in .pdf format so that the format you intended is preserved. 1.2.1 AP Physics Paper Submission Checklist 1. Is your paper complete? Does it address ALL aspects of the experiment’s requirements as set out in this document? 2. Review the marking scheme to confirm that you have not omitted any crucial aspects. 3. Does your paper conform to the AP Physics format standard? 4. Did you include and properly handle uncertainties in your data, regression and computations? 5. Did you print your report on both sides? 6. Did you print out a marking rubric? 7. Did you produce a signature page and have it signed by all group members? Typically this is on the reverse of the marking rubric. Attach this paper to your report. 8. Have you prepared your notebook for submission? Could you write a formal report from the data and comments in your notebook contents for this experiment? 9. Have you emailed your soft copy (.pdf) to Mr. van Bemmel before the appointed hour? 10. Submit your paper prior to the appointed due date and time.

Late submissions are NOT acceptable without proof of insurmountable difficulties for all 4 members of the group. Prevent this by having the report stored on more than one computer or on a web page and prepared a few days in advance. 1.3 Marking Rubric On the next page is a copy of the rubric that will be used to grade your formal lab reports. Comments from Mr. van Bemmel will be copiously written on the report and a short discussion will be had with each group when the report is returned. This may have to happen outside of class depending on our schedule. Students who wish further input should make an appointment with Mr. van Bemmel at a time of mutual convenience. Although Mr. van Bemmel will guide you and answer specific questions related to form and other aspects of a paper, he will not “go over the report” prior to handing it in. You get one chance for your mark. You are expected to read EVERY WORD of the lab manual and the course profile that pertain to submission format and use it properly. 1.4 Lab Notebooks You must submit your lab notebook along with your formal report. One Notebook per report please.

EXPERIMENT 1 – MECHANICS
SOUP CAN ROLL
BASIC REQUIREMENT
ESSENTIAL REPORT INFORMATION
PAGE LIMIT EQUIPMENT RESTRICTIONS DUE DATE
SUBMISSION TYPE
GROUP SIZE
You must use two cans of soup. One is a consommé and the other is a cream soup. The cans must have the same-labelled mass and have the same dimensions at least to eye. It is better if the soups chosen do not have chunks of material in them. These cans are to be rolled down two ramps and then on to a flat surface. The slope must be otherwise smooth and so must be the floor. One slope is to be slight permitting the consommé can to roll further. The other must be much steeper and result in the cream soup rolling further. You may have to cover the slopes with some material to prevent the can from slipping. You may also modify the floor ramp interface to allow the can to smoothly transfer from the ramp to the floor without appreciable bouncing. (If you think this matters!) In either case, one soup can will roll further than the other. Why? I want a complete analysis of the energy that is imparted to these cans and where it goes. What is going on inside the cans? What is the reason for the variation or lack thereof in the results from the two ramps? How does the situation inside the cans change with time? Justify your theory with some intelligent analyses. Full uncertainty analysis is expected. Innovative techniques to obtain better results are of interest. Your report will follow all the constraints given in the course package. However, it will also conform to the page limit set forth below. Using appropriate and reasoned analysis your report must answer the question as why one can rolled further (in both experiments) and discuss using mathematical models the probable situation inside the cans during both experiments as can be inferenced by motion of same. You are to consider how this situation evolved over the time of the roll not just the beginning and end phases. 4 pages + 1 page with the marking rubric on one side and a signature page on the reverse indicating the duties performed by each member. Please print them on BOTH sides of the paper. Only equipment found in the school lab or reasonable contents of a student’s pencil case are permitted. Experiment data must be collected at the school using the aforementioned equipment unless express permission to the contrary has been secured. Analyses can be performed in any location. Not later than 1230 – 25 September 2013 – Wednesday – No Extensions 1. Paper. Double-sided.

EXPERIMENT 1A – MECHANICS
COLLISION SIMULATION
BASIC REQUIREMENTS
You will write a simulation using code in C, C#, Visual C or C++ that will simulate a two dimensional collision. This code will first verify itself solving a 2D collision that is first head on with a motionless target, then a glancing collision with a motionless target. The verification is taken from a photocopy of a worked problem or an example from a text book that will show conclusively that your program is producing comparable results The program will then analyze a glancing collision where the target is moving. This is a challenging problem algebraically, but it can be done using a simulation. It is a problem that you can intrinsically understand and thus find the benefit of producing a simulation for these types of problems. The real problem you will face here is how to model the actual events around the collision itself. We know that the materials compress for very short time span and spring back. Assume for this experiment that your collisions are elastic. Since our laboratory equipment is limited in this area, you will use a spherical stress ball, map out its compressive properties, and use these in your simulation. BONUS: You may choose to include the rotation of the objects either as an initial condition and/or because of their impact for a maximum 20% bonus, but it must be done properly and with sound reasoning and most importantly as a simulation not a rendering. For clarity consider my primer on Simulations which can be found on my web page www.hmvb.org (general address) Submission format: Your submission must include. Please submit your report doubled sided.
ESSENTIAL REPORT INFORMATION

Photocopies of the sample problems you have used to verify the operation and accuracy of your program. 4. A verification for each sample problem to show clearly that your simulation conforms to the worked result. 4. Photocopy of a 2D glancing collision with a moving target 5. No marks or consideration given for any GUI work regardless of the quality 6. A block diagram (Flow chart) of what your program is doing to produce the data. 7. Analysis of the stress ball spring constant experiment including any uncertainties. Is it linear etc? Is spring constant a fixed value or a function?
Not enforced Only equipment found in the school lab or reasonable contents of a student’s pencil case are permitted. Experiment data must be collected at the school using the aforementioned equipment unless express permission to the contrary has been secured. Analyses can be performed in any location. Translation. The analysis of the stress ball must be done at school in our lab. The rest can be done at your convenience, but the program must be transportable to school and runable there.

EXPERIMENT 2 – SHM
SIMPLE PENDULUM BASIC REQUIREMENT
ESSENTIAL REPORT INFORMATION
PAGE LIMIT EQUIPMENT RESTRICTIONS DUE DATE
SUBMISSION TYPE
GROUP SIZE
You are to investigate the effects that bob mass and the length of a pendulum have on its period. This is to be done at various release angles and the effect these release angles have on the pendulum’s motion and period must be modelled. The differential equation for the motion of the pendulum must be derived and the constants measured. For small values of theta, the DE can be simplified using the small angle equation. You must, however, be prepared to defend what range you consider a small angle and how this estimation affects the overall precision of your work. You are also expected to empirically model the effects of large values of theta on the period. Thus your final expression will be something like Period(theta, Length) = Ideal Period(length) + Period Perturbation (theta, length). CAUTION: Observe that the square root of small g is essentially equal to Pi. Do not ignore this! You are also expected to let your pendulum swing for an extended period to determine the damping coefficient involved. You should predict what value for this coefficient is expected due in part to air resistance and compare it to what is measured. 4 pages + 1 page with the marking rubric on one side and a signature page on the reverse indicating the duties performed by each member. Please print them on BOTH sides of the paper. Pendulum should be set in a V to ensure motion in only two dimensions. Any equipment in the school inventory not in current use by a teacher or the typical items found in a student’s pencil case. Data collection must occur within the school proper using the aforementioned equipment unless special permission has been granted by the instructor. Not later than 1230 – 21 October 2013 – Monday 1.

EXPERIMENT 3 – ELECTRICITY
DC CIRCUIT ANALYSIS AC INTRODUCTION You will construct two separate circuits and analyze each of them as required below.
BASIC REQUIREMENT
ESSENTIAL REPORT INFORMATION
PAGE LIMIT EQUIPMENT RESTRICTIONS
Circuit 1: Resistor network – Connect a bridge resistor network and then predict using KCL and KVL the voltages and currents of each segment. Then measure the same and verify these values. Account for any discrepancies. Full use of uncertainty analysis is required. Caution: It helps to choose resistors that have prime numbers or your linear system can be more easily dependant making the theoretical solution harder to find. Also, do not select resistors for the different branches of your circuit that differ by more than 1 order of magnitude as this will make your uncertainty analysis difficult. Circuit 2: RC Circuit. You will construct a RC circuit and then observe the charging and discharging curves. You will have to choose values for R and C that can be read with the typical operational window of the I-books. These can be determined by appropriate attention to the theory of this type of electrical circuit. HINT: In addition, the capacitor when nearing full charge will behave like a very large resistance. These phenomena will cause your voltmeter to give erroneous readings when in parallel to the capacitor. Part of your methodology will be to devise a work around to this issue and explain it in your paper Circuit 3: Oscilloscope Familiarization You will connect the oscilloscope to the AC signal generator and obtain a waveform. From this you will measure the wave characteristics on the screen of the scope. The frequency counter can then be used to verify the frequency. You are expected to image the waveform from the screen of the scope. The TI-8x’s, I-books are not permitted on this segment as you are expected to learn the use and operation of an oscilloscope. You must use the analog scopes for this exercise. The digital scope is NOT to be used for this segment unless express permission from your instructor is given. Your report will follow all the constraints given in the course package. However, it will conform to the page limit set forth below. The resistance of the will begin to affect the readings you get from the voltage probe. You will have to sort this out. You are expected to discuss the symmetry or lack thereof of the RC profiles. Your report must indicate if your research confirms or challenges the accepted situation. 4 pages + 1 page with the marking rubric on one side and a signature page on the reverse indicating the duties performed by each member. Please print them on BOTH sides of the paper. You may use digital and / or analog voltmeters. You may also use Netbooks / TI8x / CBL voltmeters if you wish and the equipment is available. You must use Kirchhoff's work to solve these circuits. Thevenin and Norton

equivalents are not permitted in this analysis. You may however, show how these theorems conform to the work you have done, but your analysis cannot be justified exclusively by Norton or Thevenin Theorems. Not later than 1200 – 14 November 2012 – Wednesday 1. Paper. Double-sided. Attached should be the signature page and the, include the formal report marking rubric found in this document. On it you need to indicate the aspects of the lab to which each member contributed and bears the signatures of all group members as an indication of agreement with this workload distribution. 2. .pdf file sent by email.

NOTE: if there are differences between the paper and .pdf submissions, I will mark the poorer of the two papers. Not more than 4 people. No gender ratio restrictions. Groups may be changed for subsequent labs.
Note: There is only ONE unique solution to the KVL circuit in part 1. You have to be sure that the equations you choose are not linearly dependant. This can be checked when you set up your matrix by taking the determinant.

EXPERIMENT 4 – ELECTROMAGNETISM
AC CIRCUIT ANALYSIS Circuit 1: RC Phase shifting You will reconstruct the series RC circuit that was used during experiment #3. Measure whatever parameters you deem necessary with whatever equipment the school can provide to measure the reactance of the capacitor and the phase shift it generates between the current and the voltage waveforms. Research the topic of Lissajous figures and measure them for this circuit. Does the data from this observation compare well with other data collected above. What is the common use of this technique? Choose your R and C values carefully to encourage a sensible phase shift of current and voltage (You are permitted to alter the parameters of both R, C and f to obtain a reasonable Lissajous Figure. However, you are still expected to show what the phase shift would have been with the components from your Lab 3 experiment. If the phase shift of these is acceptable then fine otherwise predict and show that it is small and then choose new components to complete this part of the experiment). Your theoretical knowledge should guide you here. The values of these components have to be carefully chosen to permit impedance matching. You should research this before entering the lab. The results of this computation should also be included in your analysis.
BASIC REQUIREMENTS
Circuit 2: CLR Circuit. Now connect a CLR circuit with components whose impedance with match the output of the function generator and predict the natural frequency of this circuit. (Show the reasoning here in your report please.) Make a plot of frequency amplitude v. frequency and see if your resonance point is in fact the natural frequency. Some analysis of your curve should be effected to obtain the mathematically sound maxima here. Circuit 3: Transformer Using the coils and magnetic cores provided by school make a rudimentary transformer. Starting with a low frequency of 20 increase the frequency of the input voltage until the output voltage drops considerably. It should be much higher. Why does this happen? Where does all energy go?
the Hz off the
Circuit 4: Solenoid Using the hall effect probe (magnetic field sensor) and DC power source of a low enough voltage to keep the current in the coil at a safe level (ie. 1.5 V) measure the B field inside the solenoid and also along it longitudinal axis. Compare the values you obtained with those predicted by the theory describing your circuit. Consider using the Helmholtz coils for this Extension: Energize a second solenoid whose B field is similar, but not necessarily exactly the same as the first one. Place the second solenoid proximate to the first one at an arbitrary angle well of the axis. Compute the theoretical B field in R3 as it is distorted by the two solenoids. You are expected to model this via a computational solution of your fabrication using any software platform you like, with the exception that you cannot use a physics simulator (unless you wrote it yourself) as the primary solution calculator. You can use one to verify the results of your own work. If you are unsure about the spirit of this please see me. NOTE: Proper solutions to this challenging aspect can earn up to 110% on this paper. However, papers that do not meaningfully undertake this aspect will not receive a grade in excess of 90%.

Your report will follow all the constraints given in the course package. However, it will conform to the page limit set forth below. The resistance of the CBL will begin to affect the readings you get from the voltage probe. You will have to sort this out. The directional ability of the Hall effect probe is a problem. This is exacerbated by the local magnetic fields in the room. Part of the challenge is to sort out this problem. To complete the extension described above you would have to carefully locate the probe’s tip around the solenoid in 3D. This apparatus would be your own design. (Course work primarily deals with the fields along the longitudinal axis of the solenoid) Your report must indicate if your research confirms or challenges the accepted situation. Consider sourcing the Biot-Savart Primer on my web page. If attempting the bonus you can submit 5 pages + 1 page indicating the duties performed by each member. If not attempting the bonus then the page limit is the usual 4 pages. Oscilloscopes must be used for the AC section of this work. The remainder can be effected using any equipment in the school. The positioning tool that might be used for the extension cannot be professional in origin or expensive and thus readily obtainable or constructed by the team members from everyday materials. Not later than 1230 – 16 December 2013 - Monday (NO extension will be granted through the holidays because of the project and the fifth lab.) 1. Paper. Double-sided.

EXPERIMENT 5 – INTERFERENCE AND QUANTUM MECHANICS
DIFFRACTION, BLACK BODIES AND QUANTUM MECHANICS You are to investigate the wave properties of light and then given the results of more professional experiments, attempt to inference aspects of quantum mechanics. You may use the results of any of these experiments to support analysis in another providing your reasoning is not circular. Experiment 1: Using a 6V battery (or power supply), a 1k variable resistor and a selection of 5 or more coloured LED’s devise an experiment based on the properties of the light emitted by the LED’s that will allow measurement of Planck’s constant. Experiment 2: You are to arrange a single slit diffraction pattern produced by a red laser. Please do not bring in ‘green’ laser pointers as they are very intense. From this pattern you will take a calibrated digital image. This image will have its intensity profile analyzed by software created by your lab group. You will analyze this profile for it shape and intensity distribution and reconcile this with the theory presented in class. You will have perform analyses and/or experiments to understand the colour response of your particular digital camera
BASIC REQUIREMENTS
Experiment 3: You will arrange a prism and a light box to obtain a white light spectrum (rainbow). This will be imaged in a calibrated manner and you can use your profiling program to determine the intensity of the light as a function of colour and deflection angle in this spectrum. Due caution is required here. You will have to investigate the spectral response of the chip in your camera. Additionally you will research the typical temperature of the electric bulb in the ray box and recreate the black body curve produced by the light. This then is to be reconciled with the theoretical blackbody curve produced by a light bulb filament of the advertised temperature. You are permitted to obtain the temperature by direct measure, but your method must first be approved by Mr. van Bemmel for student and equipment safety considerations. Your analysis should also include a prediction of the bulb temperature using Wien's Law and a reconciliation of this with the sourced (or directly measured) temperature of the bulb. It can be shown in laboratories with more extensive equipment suites, that (a) the emission of light at extremely low intensities becomes chaotic and not continuous as wave propagation would suggest. The energy of these bundles of energy is proportional to colour not intensity which is irreconcilable with wave theory. (b) That the single slit diffraction pattern can be recreated over a long period of time, with single photon emission. This seems very confusing for the diffraction pattern is clearly a wave effect, but if each photon is emitted singly then what is there to interfere with? Analysis 3: Given the above data and the theoretical primer coupled with your research use your results from the single slit pattern to derive a mathematical expression for the Uncertainty Principle

METAL DETECTOR ITEM
PARTICULARS You are required to construct a device that conforms to the following. (a) A metal detector that has the following features and performance a. A display that indicates the strength of the detection in arbitrary units. b. Your device can detect a 1” interior diameter steel hex nut at a depth of no less than 20 cm in a typical soil mixture.
BASIC REQUIREMENTS
The display should be a LED type digital readout and not a simple mechanical gauge (such as a voltmeter). This display should have at least three significant digits. A selector can be used to obtain the readings. This readout should not an ‘LCD type kit”, and you are expected to wire the connections to each display digit yourself. In your testing, you are required to arrange a method to verify the accuracy of your device. A clear video record of this verification must be provided. IMPORTANT You are expected to test your project as you build and keep a record of same and the results obtained. You need to document challenges and the workarounds that you invented. Originality is stressed in the design of this project. If your work is found to conform in a major way to an existing design you marks for this aspect will not be as impressive. It is your responsibility to STRESS the original components of your design and to cite all sources you consulted.

v. Bemmel Engineers design things and technicians build them. Therefore, it will be your burden to design your project in detail prior to constructing it. Your group will be held accountable for not only the quality and originality of your design, but also for how well it conforms to your final project. Your outline will contain the following aspects. 1.
PROSPECTUS DUE 3 DEC 2012 (MONDAY)
2. 3. 4. 5.
A description of the design of the device with explanations of why this design is optimal and conforms to the laws of physics etc. A proper blueprint type diagram showing the mechanical dimensions and structure of the device. You must give details of where you sourced your ideas. I will check this. I expect some creativity and originality here not a simple copy of an Internet project. A complete wiring diagram of the device using established techniques and symbols An overall set of procedures to construct and test this device. Tolerances and expected performances during construction should be included. A production schedule and a system to monitor same that can be produced upon demand. A budget whose total cannot exceed $175 CDN (Fair market value charged for any gifts of material). This includes prototypes and mistakes.
You must cite any sources that you have consulted where the design of this device is not your own. Failing to do so will result in forfeit of the grade for that design.
ESSENTIAL FINAL REPORT INFORMATION DUE ON DEMO DAY IN JANUARY
PAGE LIMIT
Your final report to be submitted on demonstration day must include. 1. An operations manual 2. A pamphlet created in a quasi-professional manner that would accompany this project that would be used for marketing purposes. Do be careful about the claims you make, you will be held accountable! 3. All testing data presented in an intelligent format 4. Explanations of where the final product exceeds the specifications (any of them) in the prospectus and why this had to occur why they could not have been anticipated.
Prospectus: None Final Report: None However, you will be docked marks if these reports contain a lot of “padding”.

You may use basic stock materials, such as plywood, structural wood, dowel or metal rods etc. for the mechanical aspects, however the expectation is that you fabricate the device as much as possible. The electronic aspect restricts you only in the prohibition of interfacing with a computer, using microcontrollers and other small computers such as PLA’s. Integrated Circuits are permitted, but the general rule would be that they have a single purpose such as: counters, operational amplifiers, logic gates (AND, NOR etc) LED digit display drivers, LED 7 segment digits, crystal oscillators, 555 type oscillators, voltage regulators, analog to digital converters and such like. Your display device MUST be of your own design/construction. Hooking it up to a simple voltmeter would be an unsatisfactory choice. This would also apply to buying some type of device box that connects to a computer. You are expected to do this the hard way. Strain gauges permitted. EQUIPMENT RESTRICTIONS
IMPORTANT You may NOT construct your own power supply for this unit. Any aspects of this project that use voltages greater than 12V must be CSA approved. You have a budget of $175.00 CDN total for this project This includes any “donations”. The limit is “fair market value” for the items you use in your project You are strongly discouraged from attempting to use the school shops to build this device. They are understaffed and your safety is an insurmountable issue. The construction of this device will largely have to occur outside of the building. If you have intractable problems with this aspect come and see me. If you are unsure about the legality of a given part ASK ME FIRST.

FORMAL REPORT MARKING RUBRIC – PROJECT ASPECT
PERFORMANCE
DEVICE ACCURACY
CONFORMITY OF PROSPECTUS FORM OF PROSPECTUS TESTING DATA OPERATING MANUAL MARKETING FLYER BUDGET
DESCRIPTION If the device works DURING the demo you will get full marks here PLUS 10 BONUS MARKS. If you can document (i.e. video or some other evidence) that it did work, but something bad happened on demonstration day then you will earn at least 8 marks, BUT no BONUS. Beyond that, it will be the teacher’s judgement as to how close you were to getting it operational. By working the device should at least give readings that are in the same direction as the (in)decrease of the load and proportional to the stimulus. If you have substantially begun your data display system, but it is not operational, you cannot earn more than 3 marks here. If you have not begun constructing this and have only the design then you will receive zero for this section. For the rest of the marks you system would have to have some form of calibration in that when it displays some level this has physical meaning and that you have modelled and can be used to infer the mass. Hex/Octal readouts are allowed, but will not receive the highest marks. Bonus marks will be offered to projects which can sense currents substantially lower than 1A. This will not exceed 10% and is usually much lower. However, I do like being impressed! Specifically how well did the finished device correspond to that specified in the prospectus? This goes right down to dimensions and electronic part specifications etc. 1. All form rules enforced here (Operating Manual format) 2. Is the production schedule reasonable? 3. Did this group produce an up to date production status when asked? Complete and detailed Complete, professional and logical Reasonable Complete and within constraints

TOTAL GRADE
1. Chips socketed 2. Modular 3. Labelling of wires 4. Logical How original was your design. How properly did it use the available laws of physics to effect its aim. How efficient is this unit supposed to be? Documentation of designs that assisted this one. Utterly superb projects may receive grades in excess of 100%, but only when the resulting performance greatly exceeds the above standards. No mark will exceed 110%. You are reminded that this is an AP part of the course and any marks here will be adjusted.
/6 /10 %
This project will reward planning and originality along with performance. It is a challenge and I suggest that you get right at it. Good luck!
