TRANSCRIPT
The following summary was provided by Hugo Graumann in responseto the committee's questions about the status of the Junior Labs.
QUESTION: Can any of the experiments we have be reworked easilyinto a 2 hour window?
ANSWER:The short answer to your question is that we dont have any experiments thatwill fit into 2 hours without a huge reworking of the writeup. That is mostlya do-over. I think for the most part, all of the experimental apparatus could bechanged to support a 2 hour window if there are sufficient numbers of apparatusavailable for three labs in parallel, but the current writeups and procedures,would all need to be started over. Error analysis could be removed entirely.That will save about 30-40 minutes per experiment. But that is not enough.The procedures will need to be changed as well. Some, but not all, of theexperiments can be changed take advantage of computer aided data acquisition.This will require more changes to the writeup. Maybe some paragraphs andpictures could be lifted from the existing writeup. Perhaps the theorysections of existing experiments could be used nearly intact. But thatis only true if labatorial writeups will have a theory section. The 3 hourlabs are all written in a standard format that a previous laboratory committeereached consensus on. This means that all the labs are designed with thesame assumptions and targets. For example, the writeup length is tuned torequire an average student to prepare for at least 1 hour for a three hourlab. For a 2 hour labatorial we havent even discussed how much preparationtime would be required, but likely less. However, changing the preparationtime directly impacts how much prose is written down and therefore affectshow much of an existing writeup can be transferred into a labatorial and alsodetermines how extensive a theory section would be. More details below onthe apparatus that could support reworking into 2 hour format.
QUESTION: Would it be possible to get a summar of what labs etc. wehave available as well as their status?
ANSWER:Some of the lists you seek already exist, others will take a bit oftime to put together because they are in a new area for us.

These simulations can be seen at:http://phet.colorado.edu/new/simulations/index.php?cat=All_Sims&view_type=thumbs This system is fancier but requires a more modern browser to support it. Deployment of the more modern browser in the required kiosk setting is about 8 months away. The list of available simulations follows. Starred ones are physics 211/221 related

C) Physlets are a java application framework for writing web based physics demonstrations and tutorials. An overview is located at: http://webphysics.davidson.edu/physlet_resources/ Several textbooks have been written using physlets and a wide variety of physlets are freely available for noncommercial use from other contributors. Notably, Alfredo Louro has created physlets that are located at: http://www.phas.ucalgary.ca/physlets/index.htm a list follows: Mechanics Uniformly accelerated motion in 1D Free fall Projectile motion Simple harmonic motion An interaction illustrating Newton's laws. Doppler detection of extrasolar planets Ptolemy's theory of planetary motion Retrograde motion of the planets Illustration of Kepler's 1st. and 2nd. laws Kepler's 3rd. law Circular motion One-dimensional collision in the lab frame One-dimensional collision in the centre-of-mass frame Electricity & Magnetism Electric fields: A review Systems of charges Electric field lines Oersted's experiment Magnetic field due to a current loop Faraday's law Optics Virtual optical bench Waves Ripple tank - 2 source interference and Randall Stafford has a collection of physlets as well His list follows: capacitor_complex charges_opposing
equip_charges2 resistors_parallel capacitors_parallel kirchhoffs_rule resistors_series capacitors_series efield_charges1 line_charge simple_pendulum charges_equal efield_charges2 charges_generator equip_charges1 resistors_complex
The physlet system also requires a more modern browser to support it. so deployment in the required kiosk setting is about 8 months away.
D) Maple, Matlab, IDL, and Mathematica are all available to have students write and execute their own simulations but such usage is restricted to physics majors only due to volume constraints.
3) Available demonstrations
Two sorts of demonstrations are available. We of course have physical apparatus available that can be used to manually perform demonstrations. We also have an extensive collection of virtual demonstrations consisting of movies of physics demonstrations, that can be placed online for use by instructors and students.

Lastly, to answer your question, here are existing experimentsthat I think could be reworked into 2 hour labatorials thatmight fit into the physics 211/221 curriculum. All would needa new writeup.
Centripetal force (16 sets) - can be shortened to 2 hours - can raise apparatus count to 24 with moderate difficulty - cannot be converted to a digital lab Coefficient of restitution (24 sets) - can be shortened to 2 hours - already have 24 sets - can be converted to a digital lab Collisions and conserved quantities (24 sets) - can be shortened to 2 hours
- already have 24 sets - can be converted to a digital lab Conservation of energy (24 sets) - no issue with shortening - already have 24 sets - can be converted to a digital lab Free fall (16 sets) - can be shortened to 2 hours - can raise apparatus count to 24 with moderate difficulty - can be converted to a digital lab Hookes law (16 sets) - can be shortened to 2 hours - easy to raise apparatus count to 24 - can be converted to a digital lab Impact craters (24 sets) - can be shortened to 2 hours with difficulty - already have 24 sets - cannot be converted to a digital lab Inclined Atwoods machine (24 sets) - can be shortened to 2 hours - already have 24 sets - can be converted to a digital lab Kater's pendulum (16 sets) - can be shortened to 2 hours with difficulty - can raise apparatus count to 24 with moderate difficulty - can be converted to a digital lab Measureements and uncertainties - can be shortened to 2 hours - already have 24 sets - can be converted to a digital lab Moment of inertia (24 sets) - can be shortened to 2 hours - already have 24 sets - cannot be converted to a digital lab Newtons second law (24 sets) - can be shortened to 2 hours - already have 24 sets - can be converted to a digital lab Projectile motion (18 sets) - can be shortened to 2 hours - can raise apparatus count to 24 with moderate difficulty - cannot be converted to a digital lab except with video software Pulley systems (6 sets) - can be shortened to 2 hours - can raise apparatus count to 24 with moderate difficulty - can be converted to a digital lab
Simple harmonic motion and the pendulum (18 sets) - can be shortened to 2 hours - can raise apparatus count to 24 with moderate difficulty - can be converted to a digital lab with new simpler apparatus Static equilibrium and the addition of forces (16 sets) - can be shortened to 2 hours - can raise apparatus count to 24 with moderate difficulty - can be converted to a digital lab Torque and the beam balance (16 sets) - can be shortened to 2 hours - easy to raise apparatus count to 24 - cannot be converted to a digital lab Sawhorse - can be shortened to 2 hours - can raise apparatus count to 24 with moderate difficulty - can be converted to a digital lab Cavendish balance - currently untested - can only be done as a video exercise - video labs not ready yet Nonuniform acceleration on the air track - can be shortened to 2 hours - already have 24 sets - can be converted to a digital lab Ramp launched ball - currently untested - new apparatus requires construction - cannot be converted to a digital lab
In the interest of completeness, other sources of experiments and tutorialsare also available. The addition of computer sensors to our apparatus permitsthe design and construction of completely new experiments. This list is stillshort since the new apparatus has not been assimilated at this time.
Some ideas presented and/or used by Dr. Hicks and associates last semester. Acoustic motion sensor experiments - exercises while walking towards one - free fall Force plate experiments - pushing against a wall - pushing against each other - pushing on a wheeled object - standing on it - stacking force sensors on top of each other
- walking on a beam - walking on a table supported by 3 or 4 plates 1 axis accelerometer experiments - holding the accelerometer and moving it around - turning it upside down - playing catch with it - jumping 3 axis wireless accelerometer experiments - playing catch with one - swinging on the end of a pendulum - elevator trip - jumping - turning it around - circular motion, strapping it to the rim of a bicycle wheel - holding one on a skatebord or rolling chair - tumbling about each axis
Some ideas contributed by Jason Donev that could be also be used in physics 211/221 from previous similar courses he has worked on - Math review easy to support, interesting questions - Investigating motion similar to acoustic motion sensor experiment mentioned above but more complete - Rolling bodies requires construction of ramps - Free Fall similar to free fall lab mentioned above - Using a pendulum to find g easy to support and digitze - Projectile motion this is the ramp launched ball experiment mentioned above - Projectile motion in 2-d we will need air tables in order to perform this experiment but it handles projectile motion without resort to video cameras or other indirect methods of inferring the trajectory - Force table we will need force tables to perform this experiment but force tables would be a nice addition to our repertoire. Force tables can also be used to experiment with static equilibrium of planar bodies involving torques and forces in physics 341 - Static equilibrium Requires a spreadsheet infrastructure which we dont have available for first year students yet - Newtons second law similar to newtons second law lab mentioned above
- Conservation of energy similar to conservation of energy lab mentioned above - Simple harmonic motion similar to Hookes law lab mentioned above - Rotational motion pure tutorial on rotation, no apparatus needed - Conical pendulum experimental version of the whirligig demonstration listed above. I am worried about rooms filled with students swinging something over their heads. - Moment of inertia requires construction of ramps - M&M interesting edible statistical experiment. Large amount of M&M's required for a first year course. - Collisions in 2 dimensions required air tables, but would be a nice addition to our repertoire. - Air drag on a falling object. we have a balloon experiment like this that was used in physics 225 and could be used in physics 341. This version can be digitized, the balloon version likely cannot be digitized. - Air drag simulation would be good to have a simulation of air drag. This version uses a spreadsheet for which we are not set up yet for first year students.
I think that pretty much summarizes the relevant information I have at hand. Hopefully, this gives you a better picture of the current Junior laboratorysituation and answers your questions.
