**Lessons From Our Students: Response from the 2011 NYS Regents Physics Exam**
Dr. Joe Zawicki, SUNY Buffalo State College T. Johnson, Western New York Regional Information Center media type="youtube" key="LNQ7yQeXyrA" height="315" width="560" Practice questions -- consider whiteboarding / peer discourse when % correct is between 15% and 85% Great resource for misconceptions: Physics Classroom - Minds on Physics

Dr. Tom Altman, Oswego High School
Youtube Video Channel Altman Science

Regents Review: Every night students do a Regents Physics Exam page, and can use Dr. Altman's Youtube videos as a resource as they do the problems, writing down everything Dr. Altman writes down. Then they also write down a quote from the video. media type="youtube" key="MjcoDZorUC4" height="315" width="560"

Resources You Can't Teach Without
RINovelty.com American Science and Surplus

Bouncy Ball Lab
Bounce the ball, record how high it goes after one bounce, after two bounces, three bounces, etc. through 10. Graph bounce height vs. # of bounces when dropped from a set height. Shows real life data can be reflected graphically.

Slinky Lab
Longitudinal vs. Transverse waves, Hooke's Law, etc. AP: Correlating Hooke's Law to SHM, tape bouncy ball to slinky and do correlation between SHM and mass of ball as a function of the spring constant. (T=2*Pi*Sqrt(m/k)) As students own it, they want to be able to explain it.

States of Matter
Bride and Groom Bubbles (Rainbows / Soap Bubbles) Crystals for solids (grow rock candy) Bubbles for liquids (surface tension) Gases (balloons)

Polymers / States of Matter (Glowing String)
Super-sticky stuff. Wash in soapy water and air dry when it gets covered with dust. Launch across room by stretching. Launch back half and it goes better because it has more momentum. Good tie-in to Newton's 2nd Law and Momentum.

Flash Rainbow Ball (RI Novelty)
Inertial switch

3-D Fireworks Glasses (Spectral Glasses)
Roughly $.10 each in packs of 1000 Teach spectral lines Use as diffraction gratings -- red laser to find gap spacing, then green laser to find wavelength using gap spacing

Light-Up Dragon Fly
Just fun, LEDs, fluoresces

Rattlesnake Eggs (Magnets)
Magnets -- separate a little bit to get a swishing sound (rock back and forth) What happens when they bang together? same as bouncy ball getting closer to ground Repulsion -- what's really happening? Why? Promotes deeper thinking -- ask what's happening inside.

Motors and White and Red LEDs
DC motor attach to one end to light it up (use as generator)-- directional functionality, so place LEDs in parallel back-to-back. Twist motor one way -- red on. Twist other way -- white on.

Obtains them from DealExtreme.com. Very long lead times.

Magnetic Skateboard Wheels
Pickup coils between hub and wheel attached to LEDs Mount with bearings and seat so it works well

Lasers
Shine through rainbow glasses green lasers (brighter) Spin grating(s) on motor with laser E-Mail for laser e-book Many Youtube videos on these topics Channel Starcross42
